摘要
结合潮州电厂2×1 000MW机组启动的实际情况,分析了影响机组冷态启动过程的主要因素,即:锅炉热态冲洗时间,蒸汽升温、升压速度和加负荷速度,机组启动参数选择及暖机控制,设备健康状况,启动过程安排及节点控制。针对这几个因素对1 000MW机组的启动运行方式进行优化,取得了较好的节能效果。
By combining actual startup of 2 x 1 000 MW units in Chaozhou Power plant, major causes influencing cold startup process of units are analyzed： hot washing time of boilers, steam temperature rise, boosting rate and rate of loading, parameter selection for unit startup and warming-up control, health of equipments, arrangement of startup procedure as well as node control. Starting mode and operational mode of 1 000 MW units are both optimized in line with factors mentioned above, and favorable affect of energy-saving has been attained.
