Development Trend Analysis of Chinese fan Industry in the 13th Five-Year Plan
i. Development trend of key fan products and key technologies Analyzed from the economic environment and policy trend of the "13th Five-Year Plan" period, the development of the "13th Five-Year Plan" fan industry should be considered from the aspect of fan energy conservation, focus on the national energy conservation and emission reduction projects, implement the continuous innovation of fan products, meet the national demand for energy conservation and consumption reduction, and provide users with efficient and reliable all kinds of fans. In order to make the fan industry enterprises to achieve better economic benefits. 1. Energy saving emission reduction technology upgrading and upgrading of general machinery products fans, blowers, compressors are a wide range of energy consuming products, vigorously develop efficient energy saving general machinery products, and constantly improve the product technology level, energy saving in our country, improve energy efficiency, for all sectors of the national economy to achieve energy saving emission reduction goals are very important practical and long-term significance. (1) According to the national "Coal power Energy Conservation and Emission Reduction Upgrading and Transformation Action Plan (2014-2020)", the coal power industry should speed up the upgrading and transformation of coal-fired power generation, and strive to achieve the "three reduction" of coal consumption, pollution emission, coal in energy consumption and the "three increase" of the quality of safe operation, the level of technology and equipment, and the proportion of thermal coal in coal consumption. Therefore, the technology and equipment of 300,000kw sub-critical unit, 600,000kw sub-critical unit, 1000kw ultra-supercritical unit, and flue gas desulfurization and denitrification of coal-fired power station will be the focus of coal power development in the future. It is the only way to improve the reliability of the fan and reduce the energy consumption to research and develop the technical upgrading of the fan, induced draft fan, primary fan, booster fan and flue gas recirculation fan for boiler. The performance parameters of the fan can meet the requirements of 300~1200MW or above thermal power generating units (250~900m3/s, 5.0~12kPa). The pressure coefficient is higher; Equipped with a variety of variable speed adjustment (especially frequency conversion adjustment) can adjust its own performance of the fan; Dynamic and statically regulated fan units suitable for small turbine drive; The maximum efficiency of the fan is not less than 89%, with a wider range of reliable operation, wider performance regulation, higher efficiency of low load and lower noise.
