摘要
应用S7-300PLC、变频器及上位机组态软件完成了对加热炉鼓风机的监控,以加热炉煤气量为主要依据,根据空燃比,由PLC计算出风量,并以此为主要参数,通过调节PID参数控制变频器频率,来改变风机电动机转速,以实现最优控制。
The monitoring on the blower of heating furnace is realized by applying S7-300 PLC,inverter and host configuration software.Taking the gas volume of the heating furnace as main basis,PLC calculates air volume according to the air fuel ratio,which is used as the main parameter.In order to realize optimum control,the inverter frequency is controlled through adjusting PID parameters so as to change the speed of the fan motor.
