为了降低机组供电煤耗, 提高电厂经济效益, 通过对机组启动过程操作方式、主要辅机运行方式、脱硫系统设备的节能增效分析, 提出了整套机组运行优化措施。主要包括一次风机压力控制曲线优化、电除尘运行方式优化、机组启动过程优化、脱硫设备运行方式优化等。经优化后明显降低厂用电率及供电煤耗, 取得明显经济效益和社会效益。优化措施可为运行设备的节能改造提供经验和借鉴。

In order to reduce the coal consumption of the unit, improve the performance of power plant, by the exploration as well as the analysis of the start-up process, operation mode of main auxiliaries and the desulfurization. The authors put forward the optimization measures, to achieve energy saving optimization purposes, ultimately reduce the coal consumption of power plant, including to main project cloude primary air fan pressure control trend optimization, electric separate plant operation mode optimization, the start-up process optimization, desulfurization equipment operation mode optimization, etc. It can sharp decrease the electric power rate and the coal consumption rate after optimization, and obtain sharp economic benfit and social benfit. These methods provide reference for the further optimization of the equipment.
