摘要
以顺序控制和模拟量控制为依托设计锅炉风烟系统全自动启动控制方案,有序启停空气预热器及六大风机,实现风道快速建立,以及送风机、引风机和一次风机的自动并退,大大缩短了风烟系统的启动时间,有效地减轻运行人员操作强度,实践表明各项运行参数均优于手动操作过程。
Control schemes for automatic startup of a boiler air-gas system were designed based on sequence and analog micro control system to start up and shut down the air preheater and 6 big air fans in sequence,so as to achieve fast establishment of air duct and realize automatic retreat of the forced-draft fan,induced-draft fan and primary air fan,thus greatly shortening the startup time of the air-gas system and reducing the operating intensity of operators.It has been found that in the automatic control scheme,all the parameters are superior to that in manual operation mode.
