The fan industry holds a significant position in China's national economy. The compressors, blowers, and ventilators produced are applied in various fields, making substantial contributions to the country's economic construction and development. In 2016, China entered the "13th Five-Year Plan" period. Over the past two years, as the national economy has transitioned into a new normal and industrial structures have adjusted, the fan industry has encountered both opportunities and challenges.

During the "12th Five-Year Plan" period, driven by application demands, the fan industry maintained rapid growth for over a decade. However, in the mid-to-late stages of the "12th Five-Year Plan," influenced by multiple domestic and international factors, China's economic growth rate slowed significantly, affecting the fan industry as well. Market demand remained sluggish, overcapacity persisted, internal competition within the industry intensified, corporate profitability declined, and costs rose. The fan industry is undergoing unprecedented tests.

As China entered the "13th Five-Year Plan" period in 2016, with the national economy adjusting to a new normal and industrial structures transforming, the fan industry faces both opportunities and challenges. How to manage enterprise operations and development? This magazine interviewed enterprise managers, technical experts, and industry organizations in the fan industry. Through multiple channels, we compiled relevant national industrial policies, market demands in various fields, key products and technologies in the industry, and development trends during the "13th Five-Year Plan" period. We hope to provide references for industry readers, enabling them to accurately assess the situation, seize opportunities, and navigate the vast future market.

I. National Policy Orientation and Market Demand Analysis in User Fields During the "13th Five-Year Plan" Period

With changes in the global economic situation and objective environment, there is varying degrees of overcapacity or structural overcapacity in fields such as petrochemical, coal, power, metallurgy, and steel, leading to a significant reduction in new projects and severely impacting the fan industry market. During the "13th Five-Year Plan" period, under the severe conditions of de-capacity in manufacturing and coal sectors and environmental de-pollution, various fields face challenges in transformation, upgrading, and green development.

During the "13th Five-Year Plan" period in the coal industry, the main theme will be safe, efficient, and intelligent mining, as well as clean and efficient intensive utilization of coal. Adhering to the principle of coal-based substitution, biomass substitution, and transportation substitution, petroleum substitution will be developed scientifically. The development of clean coal utilization technologies will be accelerated to continuously improve the level of clean and efficient coal utilization. Priority will be given to constructing 14 large coal bases with a production capacity of 100 million tons each, including northern Shanxi, central Shanxi, eastern Shanxi, Shendong, northern Shaanxi, Huanglong, eastern Ningxia, western Shandong, Lianghuai, Yunnan-Guizhou, central Hebei, Henan, eastern Inner Mongolia, and Xinjiang. By 2020, these bases will account for 95% of the country's coal production. Advanced energy-saving and environmentally friendly power technologies will be adopted to construct nine large coal-fired power bases with a capacity of 10 million kilowatts each in areas such as Xilingol, Ordos, northern Shanxi, central Shanxi, eastern Shanxi, northern Shaanxi, Hami, Zhundong, and eastern Ningxia. With a focus on Xinjiang, Inner Mongolia, Shaanxi, and Shanxi, the research and development of coal-to-oil and coal-to-gas technologies, as well as industrial upgrading demonstration projects, will be steadily promoted. Core technologies will be mastered, energy consumption, water consumption, and pollutant emissions will be strictly controlled, and a moderate-scale coal-based fuel substitution capacity will be formed. By 2020, a petroleum substitution capacity of over 40 million tons is expected to be achieved, including 12 million tons of coal-to-oil, 16 million tons of coal (methanol)-to-olefins, 6-8 million tons of coal-to-ethylene glycol, 20 billion cubic meters of coal-to-natural gas, and 1 million tons of coal-to-aromatics.

The petrochemical industry is expected to be optimized in the following aspects during the "13th Five-Year Plan" period: The oil refining industry will accelerate the upgrading of oil product quality to fully meet the national fifth-stage standards by 2020; the olefin industry will increase the proportion of non-petroleum-based products in ethylene and propylene production through the construction of seven major bases determined by the National Development and Reform Commission, enhancing international competitiveness and self-sufficiency through raw material diversification; the aromatics industry will continue to rely primarily on petroleum routes for production while actively promoting the industrialization of coal-to-aromatics technologies and advancing the construction of diversified raw material routes and integrated aromatics-polyester industrial bases; the chemical new materials industry will focus on developing high-end polyolefin plastics, engineering plastics, high-performance fibers, functional membrane materials, etc. According to the Belt and Road Initiative, the downstream chemical industry in the oil and gas sector should also seize the development opportunities in the "Belt and Road" strategy and accelerate international capacity and equipment manufacturing cooperation.

The steel industry's development goals during the "13th Five-Year Plan" period mainly focus on resolving overcapacity, adjusting the industrial structure, curbing disorderly competition, increasing product innovation, promoting green development, and encouraging the steel industry to go global. To address overcapacity, blast furnaces with a capacity of less than 400m³ nationwide and those with a capacity of 450m³ or less in Hebei Province are considered outdated, totaling 80 million tons, and are expected to be phased out during the "13th Five-Year Plan" period. The Ministry of Industry and Information Technology has announced three batches of "Enterprises Meeting the Standard Conditions for the Steel Industry," with 77 enterprises in Hebei Province included. These 77 enterprises have a total of 307 blast furnaces, and 56 blast furnaces with a volume of 450m³ or less and 40-ton or less steel-making converters, mainly 420m³ and 450m³ blast furnaces, are planned to be phased out. Sensitive regions such as the Beijing-Tianjin-Hebei region, the Yangtze River Delta, and the Pearl River Delta will implement capacity replacement. Meanwhile, domestic blast furnaces under construction are still being put into operation, and the total actual ironmaking capacity nationwide is expected to remain at around 1 billion tons during the "13th Five-Year Plan" period. In terms of the steel industry going global, emerging markets such as Southeast Asia and Africa have great potential for steel demand growth, especially for construction steel. Additionally, mergers and acquisitions among domestic steel enterprises will be inevitable in the coming years.

Compared with many other industries, environmental protection is the most promising industry in terms of market and development potential during the "13th Five-Year Plan" period.

During the "13th Five-Year Plan" period, the three major areas of air, water, and soil pollution control will be the focus. Investment opportunities will emerge in细分 areas such as VOCs control, black and odorous water body treatment, and soil pollution prevention and control, with performance "outbreaks" expected in 2016. In air pollution control, VOCs control and ultra-low emissions will be the main growth points. It is estimated that during the "13th Five-Year Plan" period, the VOCs market size will primarily come from the sales of VOCs control and monitoring equipment, with a market space exceeding 100 billion yuan. In water pollution control, the treatment of black and odorous water bodies has become a new hotspot in the market. From 2015 to 2020, the market size for the treatment of black and odorous water bodies nationwide is expected to be around 400 billion yuan.

Additionally, during the "13th Five-Year Plan" period, a market worth over 100 billion yuan for ultra-low emission retrofits of coal-fired power plants will emerge. The State Council Executive Meeting proposed that by 2020, ultra-low emission and energy-saving retrofits of coal-fired power plants should be fully implemented to significantly reduce coal consumption for power generation and pollutant emissions. Based on unit investment estimates of 500,000 yuan/kW for dust removal retrofits, 1.2 million yuan/kW for desulfurization retrofits, and 1 million yuan/kW for "low nitrogen combustion + SCR" denitrification retrofits, achieving the original goal of retrofitting 150 million kW of units by 2020 will bring a retrofit market of 7.5 billion yuan for dust removal, 18 billion yuan for desulfurization, and 15 billion yuan for denitrification, totaling 40.5 billion yuan.

Rail transit construction has become an important means of boosting the economy and has maintained a rapid development momentum. Despite significant achievements in railway development in China in recent years, there is still a gap in railway network density and per capita railway mileage compared with developed countries, indicating great potential for construction. Therefore, during the "13th Five-Year Plan" period, China's railway investment will remain high, and the Chinese railway market will continue to be the largest in the world. Fixed asset investment in railways during the "13th Five-Year Plan" period will be 12% higher than that during the "12th Five-Year Plan" period. By 2020, the total mileage of rail transit should reach 6,000 kilometers.

In terms of oil and gas, domestic oil production will be steadily increased. Emphasis will be placed on both onshore and offshore development, consolidating old oilfields, developing new oilfields, making breakthroughs in offshore oilfields, vigorously supporting the development of low-grade resources, and constructing nine major oilfields with a production capacity of 10 million tons each, including Daqing, Liaohe, Xinjiang, Tarim, Shengli, Changqing, Bohai, South China Sea, and Yanchang.

Natural gas development will be vigorously promoted. Following the principle of developing both onshore and offshore resources, as well as conventional and unconventional resources, the capacity to increase conventional natural gas reserves will be improved, and bottlenecks in the development of unconventional natural gas will be overcome as soon as possible to promote rapid growth in natural gas reserves and production.

The exploration and development of conventional natural gas will be accelerated. Focusing on the Sichuan Basin, Ordos Basin, Tarim Basin, and South China Sea, efforts will be made to strengthen scientific and technological research in three major areas: low-grade resources in the west, deep resources in the east, and deep-water resources offshore. Exploration and development efforts will be intensified to achieve major breakthroughs and discoveries, and efforts will be made to construct eight large natural gas production bases with an annual output of over 10 billion cubic meters each. The construction of natural gas pipelines and gas storage facilities will be accelerated. Following the gas supply pattern of "west gas eastward transmission, north gas southward supply, and offshore gas landing," the construction of natural gas pipelines and gas storage facilities will be accelerated to form a national natural gas trunk pipeline network connecting import channels, major production areas, and consumption areas. By 2020, the mileage of natural gas trunk pipelines will reach 120,000 kilometers. Technologies for recovering and utilizing vented natural gas and associated gas from oilfields, as well as comprehensive energy-saving technologies for oil and gas closed gathering and transportation and technologies for using carbon dioxide for enhanced oil recovery, will be promoted in the oil and gas industry.

Nuclear power will be developed safely. Under the premise of adopting the highest international safety standards and ensuring safety, new nuclear power projects will be launched in the eastern coastal areas in a timely manner, and the construction of inland nuclear power will be studied and demonstrated. Emphasis will be placed on introducing, digesting, absorbing, and re-innovating technologies, with a focus on promoting the research and development of AP1000, CAP1400, high-temperature gas-cooled reactors, fast reactors, and reprocessing technologies. The engineering verification of domestic independent technologies will be accelerated, with a focus on constructing major demonstration projects for large advanced pressurized water reactors and high-temperature gas-cooled reactors. By 2020, the installed nuclear power capacity will reach 58 million kW, and the capacity under construction will reach 30 million kW.

Further optimization of compressor product structures will be carried out. The development of integrated compressor units will become mainstream in the future, and the measurement technologies for all compressors will also correspondingly require improvement, such as increasing the measurement of electrical parameters.

6. Development directions of intelligent manufacturing and new process technologies

In the future, the manufacturing of fans will usher in the era of intelligent manufacturing. Digitalization, electronic automation, informatization, and robotics are the basic elements of intelligent manufacturing. The application of these technologies will inevitably promote the improvement of fan manufacturing levels, stably and reliably improve product quality and work efficiency, and greatly reduce the labor intensity of operators.

With the development of a new generation of information technologies, intelligent manufacturing, new materials, and new process technologies, traditional CNC machining will achieve breakthrough developments. High efficiency, high precision, and intelligence, as well as the diversity of manufacturing methods, will be the norm for the future processing of heart components of fluid machinery such as impellers and blades. CNC electrical discharge machining technologies for complex impellers and blades, automatic welding technologies for impellers, and 3D printing technologies based on additive manufacturing will be more widely applied. To adapt to this technological transformation, corresponding material research will become the key to restricting manufacturing and processing efficiency and technology in the future, and its research is urgent.

7. The development direction of ventilators is from low-end to high-end

First, the system optimization design of ventilators should be strengthened to further improve overall performance (meeting or exceeding national first-level energy efficiency standards) and reduce costs while ensuring reliability. Second, product characteristics should be highlighted in terms of high-temperature resistance, anti-adhesion, corrosion resistance, wear resistance, noise reduction, and the application of new materials. Third, the operational analysis of user systems should be strengthened to improve the accuracy of fan design and selection and enhance the operational energy efficiency of user systems. In terms of energy-saving regulation during operation, in addition to adopting relatively advanced methods for regulating variable-pitch blades, dual-speed motors, hydraulic couplings, and various methods for regulating AC motors, new devices for speed regulation and energy saving have emerged for large ventilators—multi-stage hydraulic speed transmission devices.

8. The key development of blowers is a full range of single-stage high-speed blowers

Single-stage high-speed blowers are developing towards a full range of products with various high, medium, and low pressure ratios. Aiming for high efficiency, reliability, oil-free operation, and wide coverage, and taking serialization, modularization, and standardization as the starting points, the comprehensive performance of products will be improved. In the future, vigorous research and development work on energy-saving blowers will be carried out.

With the development of interdisciplinary studies and the emergence of new disciplines, enterprises have a more urgent need for compound technical talents who understand both management and technology. Accelerate the cultivation and reserve of compound technical talents who understand both management and technology to build a strong and excellent professional talent team.

5. Strengthening the investment in new equipment and new processes

In today's world, technological development is changing rapidly. For the manufacturing industry, new equipment and new processes represent efficiency, quality, and reputation. During the "13th Five-Year Plan" period, enterprises need to continue to increase investment scales and use new equipment and apply new processes to solve problems in enterprise processing.

6. Enterprise informatization construction

Currently, the ERP systems operated by enterprises can basically meet the requirements of a unified information platform integrating enterprise production, operation, and decision-making. Some enterprises have launched product lifecycle management software (PLM), which standardizes the design process, improves the circulation speed of technical documents, enhances the commonality of parts and components, significantly improves work efficiency, and shortens the research and development cycle. The next step is to further improve the informatization level to better integrate logistics, capital flow, personnel flow, and data flow in real-time, efficiently, dynamically, and seamlessly, promote the adjustment and optimization of the industrial structure, and promote the modernization of enterprise management and the improvement of technological levels.

7. Expanding financing channels and exploring new business models

Lay a solid financial foundation for expanding and strengthening enterprises, advocate the adoption of various operational models such as the energy performance contracting model and the PPP model to support the sustainable development of enterprises.

IV. Overall Development Goals of the Fan Industry During the "13th Five-Year Plan" Period

By the end of the "13th Five-Year Plan" period, China's fan industry enterprises should strive to become world-leading providers of compressor, blower, and ventilator products, services, and system solutions. Transform from a manufacturing-oriented enterprise to a manufacturing and service-oriented enterprise. On the basis of single-unit manufacturing and sales, diversify into equipment complete sets and productive service industries. Transform from being primarily oriented towards the Chinese market to being primarily oriented towards the domestic market and supplemented by the international market.

1. Maintain moderate growth in the industry's economy. During the "13th Five-Year Plan" period, the economic growth rate of the fan industry should be maintained at 6%-8%.

2. The localization rate of major technological equipment has been significantly improved. By 2020, the localization rate of fans in major fields such as petrochemicals, nuclear power, ultra-supercritical thermal power, oil and gas gathering and transmission, natural gas liquefaction, and deep coal processing will reach over 80%.

3. The proportion of mid-to-high-end fan products has significantly increased. Strengthen the research and development of mid-to-high-end and energy-saving products, and increase the proportion of high-end products such as large air separation units, centrifugal compressors, and axial flow compressors from the current 50% to over 70%.

4. The number of large and medium-sized enterprises has further expanded. By 2020, the fan industry will form two enterprises with an output value of over 10 billion yuan; 3-5 enterprises with an output value of 5-10 billion yuan; and 8-10 enterprises with an output value of 1-5 billion yuan.

5. Promote the "integration of information technology with industrialization" in enterprises. During the "13th Five-Year Plan" period, the fan industry will further move towards informatization, with key backbone enterprises driving other enterprises to increase the development and promotion and application of flexible manufacturing systems and computer integrated manufacturing systems, and develop towards intelligent manufacturing, gradually realizing the information digitization of products and the intelligence of the manufacturing process.

6. Strengthen the adjustment of the industrial structure. To address the contradiction of overcapacity in low-efficiency ventilator product production, structural adjustments will be carried out centered around "control, elimination, transformation, and improvement." Product elimination suggestions will be timely provided to relevant government departments, and product elimination catalogs will be formulated in cooperation with the government to guide enterprises to compress and eliminate outdated production capacities based on market orientation, promote technological progress and industrial structure upgrading in enterprises, and develop from low-end products to high-end products.

7. Gradually improve the complete set and integration capabilities of products.

For a long time, China's equipment manufacturing enterprises have focused on single-unit manufacturing, with poor engineering complete set and integration capabilities and low product concentration. However, renowned foreign manufacturing companies not only produce centrifugal compressors and axial flow compressors but also gas turbines, steam turbines, expanders, reciprocating compressors, pumps, screw pumps, etc. Enterprises can only transform from pure manufacturing to engineering complete sets and modern service industries by increasing the research and development efforts of high-end products, relying on national major equipment projects, establishing engineering research centers and several enterprise strategic alliances, and jointly carrying out joint design and research.

8. Carry out styling design and industrial design of products

Styling design of products refers to design related to the morphological aspects of machine styling. It includes morphological design that fully expresses the functions of the machine, design that realizes the methods and processes of morphological structures, and human-machine relationship design that achieves convenience, suitability, and environmental coordination. Through the styling design of machines, the functional, structural, process, material, human-machine relationship, morphological, color, and other factors of the machine, as well as engineering and technical issues related to styling design, and the artistic expression of the styling form are naturally integrated to form a unified sensory image and a unified social image, which can play a role in enhancing, shaping, and disseminating the corporate image, strengthening the overall quality of the enterprise, creating brand effects, and winning profits in the fierce market competition. Industrial design of products should attract the attention of compressor manufacturing enterprises.

9. Encourage the establishment of product reliability testing platforms by national key laboratories for compressor technology to provide technical services for product reliability in enterprises and gradually implement product reliability assessments throughout the industry; encourage enterprises to accelerate the construction of technical infrastructure platforms for product testing and detection to provide basic guarantees for product development and performance testing. It is suggested that relevant government departments provide support in terms of policies and funds.

10. Expand the international market. Implement the "going global" development strategy, utilize both domestic and international markets, focus on expanding export channels, actively utilize the "Silk Road Economic Belt," the "21st Century Maritime Silk Road," and the construction of six major economic corridors including the China-Mongolia-Russia Economic Corridor, the New Eurasian Continental Bridge, the China-Central Asia-West Asia Economic Corridor, the China-Indochina Peninsula Economic Corridor, the China-Pakistan Economic Corridor, and the Bangladesh-China-India-Myanmar Economic Corridor, and fully utilize the preferential policies of zero tariffs to expand the export of fan products.

11. Develop productive service industries and take service businesses as the driving force for takeoff.

With the progress and improvement of manufacturing technologies, a trend has emerged worldwide where the high added value of each link in the manufacturing industry chain is continuously shifting towards the upstream and downstream ends of the chain, that is, towards engineering complete sets, technological development, maintenance, and remanufacturing services. The separation of productive service industries from manufacturing industries is an inevitable trend in the rapid development of global manufacturing industries. Some internationally renowned large manufacturing enterprises have achieved transformations to service providers, with service business income exceeding 50%. Therefore, enterprises in the fan industry should expand their business scales, promote their future development, extend from single-unit equipment manufacturing and supply to unit engineering of equipment complete sets and process flow units, and provide system solutions to customers through multiple service models—implement turnkey projects and promote the transformation and upgrading of their industrial structures.
