Abstract
A burner for oil or gas is controlled by a thermocouple to maintain a predetermined minimum operating temperature within ignition chambers employed to incinerate partially-burned distillation products conducted from the space above a coal charge in a coke oven. Passageways in the side walls of the coke oven conduct the partially-burned distillation products from the space above the coal charge into sole heating flues located below the oven floor from where such distillation products are conducted into the ignition chambers. A stack is connected to the ignition chambers by a conduit which includes a recuperator used to reduce the temperature of the burned gases and provides a heated secondary air supply. This air supply is fed by separate pipes including control valves into one of the ignition chambers and into the passageways in the side walls of the coke oven. The stack includes a gas washer and a fan used to control the draw on the ignition chambers as well as the coke oven.
