摘　　要：上海申能临港燃机发电有限公司作为调峰电厂,机组启停时间完全按照电网负荷需要调整,由于电厂启动锅炉需在机组停机前由备用切至运行,由此造成启动锅炉燃料的浪费。通过调整停机各辅助系统的投用时间,以此解决启动锅炉提前启动的问题。Shanghai Shenneng Lingang Gas Turbine is a peak-shaving power plant.The start and stop time of the unit is fully adjusted according to the grid load.Since the start of the boiler in our plant needs to be switched from standby to operation before the unit is shut down,this causes a waste of fuel for the starter..By adjusting the commissioning time of each auxiliary system during shutdown,the problem of early start of the starting furnace is solved.
