摘　　要：结合行业标准、设备厂家标准及CCPP机组特点,制定出一套化学监督标准。针对给水、炉水处理控制滞后、非线性特性,从管理和加药装置工艺设计上保证配制药剂浓度的稳定,以调节加药泵运行频率控制药剂量。A set of standard for chemicals supervision was drawn up based on industrial and enterprise specifications and the characteristics of CCPP Unit. As control of water feed and furnace water treatment have hysteresis and nonlinear nature, the concentration consisten-cy of chemical agent preparation was ensured from the aspects of management and design of chemical addition device to control the amount of addition by regulating the running frequen-cy of agent pump.
