Energy saving analysis of combined heating system of steam driven induced draft fan
摘要
Abstract
Aim at the problem that auxiliary power consumption rate dramatically increased after the modification of capacity expansion of electric induced draft fan in a pure condensing generator with large unit capacity and heating demand,a heating system combining steam driven induced draft fan and heating demand is put forward in this study.This system can solve the problem that the output of electric induced draft fan is insufficient due to the capacity expansion of environmental protection facilities.Besides,this system can increase the heating capacity,which achieves the comprehensive cascade utilization of steam energy and significantly decreases the auxiliary power consumption and energy consumption.Moreover,this system has been applied to the 2×630 MW supercritical unit of coal-electricity integrated corporation limited of Guodian Xingyang Power Plant.The results show that,after the modification,during the non-heating period the coal consumption rate,auxiliary power consumption and comprehensive coal consumption are decreased by 0.435 g/(kW·h),1.35％ and 4.485 g/(kW·h),respectively.During the heating period,the coal consumption rate,auxiliary power consumption and comprehensive coal consumption are decreased by 4.35 g/(kW·h),1.7％ and 9.45 g/(kW·h),respectively.5 220 tons of standard coal are saved each year,more than 44 million kW·h of on-grid electricity is added,and the annual earnings of energy-saving and multi-generation yield are about 10.914 million yuan.Therefore,the energy saving effect and economic benefits are remarkable.关键词
