我公司原分解炉喂煤方式为中控操作员根据分解炉出口温度结合经验判断增、减煤量,由于各人经验、操作水平、责任心的差别,有时会造成尾煤用量超实际所需喂煤量,同时人工加煤波动大会造成分解炉出口温度波动较大,往往会造成尾煤的不完全燃烧,导致整体煤耗升高。自从2013年5月参考集团其他公司做法,将控制方式改为PID控制后,保证了喂煤量和分解炉出口温度的稳定。1 PID自动控制尾煤转子秤喂煤量的思路 The original method of decomposing furnace coal feeding by our company is based on the experience of the operator of the controlled furnace combined with the outlet temperature of the decomposing furnace to judge the increase and reduction of coal amount. Due to the difference of experience, operation level and sense of responsibility of each person, Feeding coal, while artificial coal fluctuations caused by fluctuations in the assembly furnace exit temperature fluctuations, often resulting in incomplete combustion of tailings, resulting in increased overall coal consumption. Since May 2013, referring to other companies in the group, changing the control mode to PID control ensured the feedstock volume and the exit temperature of the calciner. 1 PID automatic control coal tail rotor coal feeding ideas
