Optimization and application of pressure regulation technology for gas collection pipe of a 7 m top-charging coke oven
The principles and existing problems of pressure control in the original gas collection pipe and suction control before the blower of Tangshan Jiahua Coal Chemical Co.,Ltd.were introduced.Based on the actual production situation of the company and combined with traditional gas collection pipe pressure regulation technology,a pressure regulation scheme for coke oven gas collection pipes without the single pipe regulation technology had been optimized and designed,and put into renovation and application.The optimized plan fully utilized the coordinated adjustment of process flap valve,machine front flap valve and large circulation flap valve,and coal loading signal was introduced to eliminate the pressure impact of coal loading operation on the main gas collection pipe,achieving a long term stable operation of the coke oven gas collection pipe pressure.
