According to the characteristics curve of the pressure control valve on gas main pipe,this paper establishes a mathematical model of variables of pressure control valve. On that basis,step dis-turbance of the system is removed with feed-forward control method according to the characteristic of control valve and process requirement of coke oven heating system,so that the pressure of recycled gas main pipe could be stabilized at the prescribed value,and the system has been well operated at site.
