A radiant tube furnace has a pair of regenerative burners (13, 14) firing alternately into opposite ends of the tube (12). There is a respective inlet (28, 31) at each end of the tube (12) for admitting gas to the tube (12) immediately adjacent to the wall (10) thereof and these inlets communicate via a duct (32) so that products of combustion are drawn from one end of the tube (12) and introduced into the opposite end of the tube (12), where the burner (13, 14) is firing. |
