| 摘要 |
The invention concerns a DFI (Direct Flame Impingement) burner (1), comprising a metal block (2) and at least two nozzles (3,4) projecting out from the metal block (2), characterized in that each of the nozzles (3,4) comprises a set of nozzle openings (11,12a,12b) comprising at least one fuel opening (11) and at least one oxidant opening (12a,12b), in that the set of openings (11,12a,12b) in each nozzle (3,4) is identical, comprising corresponding fuel and oxidant openings (11,12a,12b), in that the metal block (2) comprises only one main fuel inlet (5) and only one main oxidant inlet (6), in that the main oxidant inlet (6) is connected to at least one main oxidant chamber (8a,8b), connected to at least one oxidant opening (12a,12b) in the set of openings in each nozzle (3,4) via apertures (10a,10b) of identical length and cross section, and in that the main fuel inlet (5) is connected to at least one main fuel chamber (7), connected to at least one fuel opening (11) in the set of openings in each nozzle (3,4) via apertures (9) of identical length and cross section, whereby the gas pressure of fuel or oxidant is equal over all corresponding fuel and oxidant openings (11,12a,12b) in the set of openings in each nozzle (3,4). |
