Abstract

139,276. August, J. R. C. Feb. 12, 1919. Metal-heating, glass, pottery &c. furnaces.- In a gas-fired furnace for hardening or tempering steel tools, or for heating or annealing metals, glass, pottery, and the like, regeneratively-heated gas and air are supplied through pipes 3, 4 respectively to a combustion chamber 5 having inclined sides and floor 7 upwardlv inclined towards the outlet leading into the pre-heating chamber 1, which is in communication with the hardening-chamber 2. The roof of the combustion chamber is rounded and serves to deflect the gas downwards. The combustion products from the furnace escape into a hood 8, which encloses the air regenerator tubes 11 cast integrally with headers and with the hood. The gas is heated in pipes arranged as shown above the air conduits. A similar combustion chamber 5 is arranged on the opposite side of the chamber 1.
