摘　　要：结合国电青山热电有限公司新建2×350MW超临界热电联产燃煤机组甩50%负荷和100%负荷试验,重点从锅炉侧主、再蒸汽参数变化、锅炉给水流量变化及炉膛负压变化角度,探讨甩负荷试验过程中避免锅炉熄火的参数控制方法,提出了操作建议。On the basis of the successful experience in 50% load rejection and 100% load rejection tests of 2×350 MW supercritical coal-fired power and thermal units in Hubei Guodian Qingshang Co-generation Co.Ltd.,the control measures for avoiding the flame extinction of the boiler were discussed.The focus was put on the analysis about the changes in the load rejection tests process,such as the superheat steam and reheat steam parameters,the feed water flow of the boiler,and the pressure in the furnace.At last,several significantly operating suggestions were concluded.
