1自备电厂存在的问题(1)自备机组发电效率低,单位能耗偏高。根据原国家电监会2007年发布的《全国企业自备电厂情况通报》,自备电厂主要集中在高耗能企业,其中:钢铁冶金企业装机容量占34.7%,化工造纸占19.6%,石油石化占11.6%;单机总体偏小,其中单机容量在10万千瓦的小机组占比达到70%,5万千瓦以下的达到了60%;单位能耗偏高,其中平均供电煤耗为449克/千瓦时,比电力行业平均水
1 own-owned power plant problems (1) owned power generation unit is inefficient, high energy consumption per unit. According to the “Circular of the State Owned Enterprise-owned Power Plants” released by the former State Electricity Regulatory Commission in 2007, the self-provided power plants are mainly concentrated in high-energy-consuming enterprises, of which, the installed capacity of steel and metallurgical enterprises accounts for 34.7%, chemical papermaking accounts for 19.6% Accounting for 11.6%. The overall stand-alone capacity is small, of which the proportion of small unit with unit capacity of 100,000 kilowatts is 70% and that of units with less than 50,000 kilowatts is 60%. The unit energy consumption is high with the average coal consumption of 449 g / When compared to the electricity industry average water
