Abstract:

A furnace having an ash discharge system which collects and receives siftings falling from portions of the incinerator grate and at the same time provides for controlled emission of air for combustion of the fuel to separate sections of the grate independently. The siftings removal system includes a hopper for receiving siftings that also forms part of an air plenum for directing and controlling the flow of combustion air to the furnace. A rotating conveyor is disposed within the hopper for removing ash from the hopper. An air seal divides the hopper into separate air chambers, each of the chambers being independently supplied with a source of pressurized air. The system also includes a means to separately control the air supply to each chamber.
