Abstract (en)

A burner (10) 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 (16) and an outer housing (22) spaced from the inner wall to form a hollow interior (26) between the inner wall and the housing. The inner wall terminates adjacent a surrounding portion (31) of the housing to form a narrow opening (30) from the hollow interior which extends around the periphery of the inner wall structure. A gas supply pipe (32) located in th hollow interior surrounds the inner wall structure (16) and directs the flow of gas under pressure toward the narrow peripheral opening (30). The inner wall (16) forms an air supply pipe and air is forced under pressure through the air supply pipe and past the narrow opening.
