Abstract
A flat-flame burner for reheat, holding, and heat-treatment furnaces for treating iron and steel products. It has at least one fuel-injection pipe lying along the axis of the body of the burner, a combustion tunnel and a combustion-air feed, the air being distributed in and by the body. The fuel is introduced via the injection pipe or pipes through at least one axial orifice lying in a plane close to the external plane of the combustion tunnel, into the combustion products. This produces a first dilution of the fuel in these combustion products, the fuel/combustion products mixture thus obtained being diluted further in the combustion air.
