摘要
大型钢铁公司内部蒸汽余能、余热可利用空间较大,公司自备300 MW发电机组三段抽汽经减温减压后送至蒸汽管网,具有一定的能源损失及季节性波动,根据机组抽汽能力增设发电机组,使蒸汽能源二次分配、利用,有效回收余能,发电创效。
Large steelmakers have great internal waste energy and waste heat to be re- covered. The three-stage steam extraction of the self-owned 300 MW power generating unit of Shougang Jingtang Steel was delivered to steam pipe network after temperature and pres- sure reduction, having some energy loss and seasonal fluctuation. Power generating units were added based on steam extraction capacity, resulting in secondary distribution and utilization of steam energy, effective recovery of waste energy and creating benefit with power generating.
