METHOD OF KEEPING HOT AN INOPERATIVE REGENERATOR DURING REPAIR IN A COKE-OVEN BATTERY

摘要

"A method of keeping hot an inoperative regenerator during repair in a coke-oven battery" A regenerator in a coke-oven battery which is inoperative during a repair is kept hot in order to prevent the formation of cracks in its structure due to thermal contraction. This is achieved in a simple, effective and cheap way by supplying hot waste gas to the inoperative regenerator from a location upstream (in the waste gas flow direction) of the checker work of one or more operating regenerators through added by-pass conduits during the repair. The temperature of the regenerator can be monitored and controlled by adjustment of the waste gas supply.
