Title (EN) OXYGEN-FUEL BURNER WITH LANCING CAPABILITY AND METHOD OF PRODUCING STEEL
(FR) BRULEUR A OXYGENE-COMBUSTIBLE A CAPACITE D'OXYCOUPAGE ET PROCEDE DE PRODUCTION D'ACIER
Abstract:
(EN) An oxygen-fuel burner of the rocket burner type includes a graphite burner block (11) for direct exposure to the interior of a furnace, and a cylindrical combustion chamber (115) formed through the hot face of the burner block and extending into the burner block. An oxygen supply conduit (15) delivers oxygen to the combustion chamber along the center line of the combustion chamber and fuel supply ducts (109 and 110) deliver fuel to the combustion chamber at the concave surface of the combustion chamber, whereby fuel surrounds the stream of oxygen. Excess oxygen can be supplied by the nozzle (82) to provide more oxygen than consumed by the flame, whereby the excess oxygen is preheated as it passes through the flame and can be used in a lancing process in the refining of steel.
(FR) Un brûleur à oxygène-combustible du type à brûleur de fusée comprend un bloc de brûleur de graphite (11) pour l'exposition directe à l'intérieur d'un four, et une chambre cylindrique de combustion (115) formée au travers de la face chaude du bloc de brûleur et s'étendant dans le bloc de brûleur. Une conduite d'alimentation en oxygène (15) amène l'oxygène à la chambre de combustion le long de la ligne centrale de la chambre de combustion et des conduites d'alimentation en combustible (109 et 110) amènent le combustible vers la chambre de combustion à la surface concave de la chambre de combustion, où le combustible entoure le jet d'oxygène. Une quantité supplémentaire d'oxygène peut être fournie par l'ajutage (82) afin de disposer de davantage d'oxygène qu'il n'est consommé par la flamme, cette quantité supplémentaire d'oxygène étant préchauffée lorsqu'elle traverse la flamme et peut être utilisée dans un procédé d'oxycoupage dans le raffinage de l'acier.
