Abstract
Abstract As in Applicant''s patented apparatus U.S. Pat. No. 3,777,676, there are means for feeding the fuel onto the fuel retainer along an elongated path passing through the preliminary incineration chamber from the fuel intake. There are also fluid transfer means, including blower means, for pressurizing the atmosphere in the preliminary and post incineration chambers with an oxygencontaining gas, while purging the whole of the atmosphere from the preliminary incineration chamber and discharging the same into the post incineration chamber. Now, the fluid transfer means also include means which are operative to form a plenum between the chambers and the blower means, on either or both of the intake and discharge sides of the blower means, which plenum or plenums extend lengthwise of the fuel flow path and communicate with the fuel flow path in directions crosswise thereof. Also, the post incineration chamber has a sump in the bottom thereof, and there are means movably associated with the sump to collect and discharge slag from the sump, relatively outside of the furnace. In addition, the intake side of the blower means is interconnected with the furnace on at least one side of the opening to the outside thereof, to collect and return fly ash to the post incineration chamber which has settled to the bottom of the furnace.
