Abstract:

The coke oven exhausting system consists of gas collecting main,gas exhauster,primary cooler and exhauster speed adjusting gear.It is used to adjust the speed of gas exhauster to keep a stable suction force before primary cooler and stable pressure in gas collecting main,so coke oven gas can be transmitted stably.Two models of working condition are established to control the system with different GPC parameters.The result shows that this system has strong robustness to restrain disturbance,and stable transmission of raw coke oven gas is achieved by the gas exhausting system.
