摘要
The flat flame oxy-fuel burner of the present invention comprises a vapor phase fuel nozzle having a hydraulic diameter (Dh -NG ) and an aspect ratio (w / a) of at least 2; A primary oxidant conduit surrounding the fuel nozzle to form an annular primary oxidant nozzle between the fuel nozzle and the primary oxidant conduit; And a pre-combustor extending from an outlet end of the fuel and oxidant nozzles and having a length L and a hydraulic diameter D h , the oxidant duct having a height b, each of the fuel nozzles and the oxidant nozzles outlet ends are aligned, the ratio (L / D h) is not less than 4 is 0, the ratio (L / D h-NG) is 12 or less non-zero, the dimensions a, b, w is the burner is 0.05 to 1 When operating at MMBtu / hr, it is sized to produce a primary oxidant Reynolds number of 200 to 22,000.
