Abstract
A burner, for direct flame impingement on steel materials with simultaneous redn., has peripheral combustion air outlets in the inner wall of an open-ended tubular burner wall casing and fuel gas outlets at the centre of the casing. The outlets are arranged so that (a) the air outlet direction makes an angle of max. 60 deg. wrt. a tangent to the inner periphery pf the casing; (b) the distance N, in the axial direction of the burner, between the air outlets and the fuel gas outlets, has a value between -O.ID and + 0.4D (D = internal diameter of the burner) and is negative when the fuel gas outlets are nearer the casing outlet or positive when the air outlets are nearer the casing outler; and (c) the distance L, from the air outlets to the casing outlet, is between 0.6D and 3.OD.
