Research on CO emission control methods of the 7-meter coke oven in Hanbao Coking Plant
In Hanbao Coking Plant,there exists a phenomenon of high CO concentration in the flue gas emissions of two sets of 7m coke oven systems.With the increasingly strict management of environmental protection,the reaserch on how to reduce the CO emission from the coke oven has become an extremely significant work for the coking plant.Both the blast furnace gas consumption and coke dry quenching gas content have an impact on the CO emission of the coke oven.In order to make clear the influence,this reaserch analyses the content changes of CO released from the coke oven exchanging and heating process,and adopts methods such as adjusting the consumption of blast furnace gas in the heating gas of the coke oven and utilizing the maintenance period of dry quenching coke to change the process parameters of the coke oven.The study works out the relationship between blast furnace gas consumption and CO emissions in coke oven flue gas,as well as the changes in CO content after using dry quenching furnace flue gas.Based on this,it studies the source composition of CO in coke oven flue gas,and puts forward corresponding measures to reduce CO emissions in flue gas.
