HEATING DEVICE FOR HEAT REGENERATING COKE OVENS

摘要

A heating system for regenerative coke oven batteries having a plurality of coke oven chambers separated by heating walls and a plurality of regenerators extending the length of the coke oven for preheating air and cooling hot waste gases comprises a plurality of spaced heating ducts extending upwardly in the heating walls which are grouped into two adjacent pairs of heating ducts. The ducts in each group of four heating ducts are separated by first and second binder walls with the first binder walls carrying one binder duct for supplying air and discharging hot waste to and from adjacent heat ducts in one of the pairs in the group. The second wall is either provided with no heating ducts or a pair of heating ducts. A horizontal channel connects the tops of all four heating ducts in each group and the lower end of each heating duct is provided with a rich gas supply nozzle.
