Abstract: 361,551. Gaseous-fuel furnaces; regenerators. PRIEST, C. F., 123, Albert Road, Middlesbrough. Oct. 24, 1930, No. 32051. [Class 51 (i).] In a gas-fired reheating furnace for the treatment of steel and other materials in which a smoky atmosphere is provided within the heating chamber, the smoky gaseous mixture leaving the heating chamber is provided with a supply of secondary air to effect complete combustion, the heat thus obtained being used to preheat the primary or secondary air supply or both. The furnace 1 comprises a heating chamber 2 and hearth 3 beneath which is arranged a series of vertical walls forming chambers such as 4a each of which is divided as by shelves 5a into tortuous passages 8a. These chambers are provided with air and gas ports and are connected alternately to air and gas supply pipes, the pipes and corresponding ports of alternate chambers being disposed on opposite sides of the furnace: Alternate chambers 4a are supplied at the bottom. with primary air through ports 9a from a supply main 15 and fan 23. This air is heated by the exhaust gases flowing out through the adjacent chambers and at the top of the chambers 4a is supplied with primary fuel gas from a pipe 18 and ports 10a, the mixture burning in the passages 11a beneath the hearth and passing to the heating chamber by way of ports 12a, a further supply of gas being added from a pipe 19 and ports 13a to form a smoky atmosphere. Cold primary air may be used if desired. The products of combustion are exhausted at the opposite side of the heating chamber through ports 12b into the other set of alternate chambers where secondary air is supplied to complete combustion. The supply and exhaust pipes to the alternate chambers are connected by simultaneously operated valves so that the paths of the gases may be reversed, the recuperator then acting to some extent as a reversible regenerator. The ports such as 12a are then exhaust ports for the combustion products, the gas supply to ports 10a, 13a is cut off, the. main 15 connected to a suction fan 25 and secondary air is supplied through ports 14a from a pipe 21. To effect the reversal, the main 15 and the corresponding main on the opposite side of the furnace are connected alternately to supply and exhaust pipes 28, 29 by a four-way valve 27. Corresponding pipes such as 19 feeding the secondary gas ports and also the primary ports through pipes such as 18 are alternately put into communication with the main supply 31 by a three-way valve 30. Another threeway valve 34 serves to put the corresponding secondary air supply pipes such as 21 alternately into communication with the main supply pipe 35. All the valves are operated from a common shaft 36. Ports may be provided in the hearth 3 near a charging door 42, which ports communicate with a stack 44 for exhausting air admitted to the heating chamber 2 when the door is opened. Some or all of the supply and exhaust ports may be independently controlled by valves 45.
