Abstract of the Disclosure A burner for soaking pit furnaces produces essentially complete combustion of the gas and air mixed in the burner. The burner includes a tubular inner wall structure and an outer housing spaced from the inner wall to form a hollow interior between the inner wall and the housing. The inner wall terminates adjacent a surrounding portion of the housing to form a narrow opening from the hollow interior which extends around the periphery of the inner wall structure A gas supply pipe located in the hollow interior surrounds the inner wall structure and directs the flow of gas under pressure toward the narrow peripheral opening. In one embodiment, the inner wall forms an air supply pipe and air is forced under pressure through the air supply pipe and past the narrow opening. Gas flowing through the narrow opening surrounds and is drawn into air flowing past the opening to form a combustible gas/air mixture. In another embodiment, air under pressure is introduced to the hollow interior where it mixes completely with the gas to form a combustible gas/air mixture which is forced under pressure through the narrow opening. In both instances, a clean-burning, continuous blue flame is produced in the soaking pit. The invention also includes soaking pits for heating ingots and including such burners and methods of supplying heat to such soaking pit furnaces.
