Method for reducing the flame temperature of a burner and burner intended therefor

摘要: A method for reducing the flame temperature of an oxy-fuel burner, such a burner comprising central oxygen nozzle at least one fuel radially spaced from nozzle, and peripheral greater radial distance than all nozzles being substantially parallel, casing surrounding whose forward end lies in plane right angles to longitudinal axis rear portion defines chamber, means supply oxygen-containing gas fuel, respectively, nozzles. The is form Laval or, if it annular same cross-sectional variation as throughout its entire length. major fraction volume requisite combustion caused pass great speed through disposed about thereby aspirate ambient atmosphere which lower flame, before reacts flame.
