Abstract

456,999. Regenerative furnaces. BRASSERT & CO., Ltd., H. A., DAWSON, H. C., and THOMSON, T., Brook House, Walbrook, London. Sept. 24, 1935, No. 26493. [Class 51 (i)] In a method of waste heat recovery for furnaces in which the waste combustion gases are passed successively through heat-exchangers arranged in series, the fuel is preheated by one exchanger, the combustion air by the other, at least one of the exchangers is of metal and the waste gases are maintained continuously in contact with the second heat-exchanger. The Figure shows the invention applied to a continuous billet reheating furnace. Waste gases pass through a recuperator b which preheats the fuel gas and a recuperator c which preheats the air supply. The air and gas are supplied under pressure through pipes k and g respectively. The burner j is preferably of the type described in Specification 243,222, [Class 51 (i)]. The air supply is controlled in accordance with the gas supply by means of a regulator m of the type described in Specification 224,655, [Class 8 (ii)]. If desired, the gas supply may be automatically controlled in accordance with the temperature or pressure within the furnace. A damper o in the flue may be automatically regulated to maintain a constant draught at any point such as s in the furnace. The temperature of the heat-exchangers may be controlled automatically or manually by the addition of cool waste gases at the point p. Burners may be provided at the sides and ends of the furnace, those at the ends having insufficient air for complete combustion and those at the sides having an excess of air sufficient to complete the combustion of the partially burnt gases from the end burners. In a modification, the first heat-exchanger comprises a reversible regenerator with checkerwork as described in Specifications 325,789, [Class 51 (i)], 355,674, and 389,881.
