据1982年机械工业部调查,风机用电约占全国发电量的10%;另据1998年冶金部的规划资料,我国金属矿山的风机用电量占采矿用电的30%;钢铁工业的风机用电量占其生产用电的20%;煤炭工业的风机用电量占全国煤炭工业用电的17%。由此可见,风机节能在国民经济各部门中的地位和作用是举足 According to a survey conducted by the Ministry of Machinery Industry in 1982, about 10% of the country’s generating capacity was used for fan power. According to the planning data of the Ministry of Metallurgical Industry in 1998, the power consumption of fan mines in China’s metal mines accounted for 30% of the mining electricity consumption; Electricity consumption accounts for 20% of the electricity consumed by its production. The power consumption of fans in the coal industry accounts for 17% of the electricity consumed by the coal industry in the country. This shows that the energy-saving fan in the various sectors of the national economy’s position and role is sufficient
