METHOD AND DEVICE FOR KEEPING COKE FURNACE CHAMBERS HOT WHEN A WASTE HEAT BOILER IS STOPPED

摘要

The invention relates to a process for keeping coke oven chambers hot during the stoppage of a waste heat boiler  wherein the coke oven chambers are kept hot during the stoppage after emptying using externally heated burners  as a result of which a flue gas low in pollutants is obtained from said burners  such that the waste heat boilers which  during normal operation  cool the flue gases from the coke oven benches and use said gases to produce steam can be shut off and overhauled  and a flue gas low in pollutants which can be dissipated directly into the atmosphere is obtained by the burner operation. .....
