Abstract

1,209,987. Burners; thermal lances. STEEL CO. OF WALES Ltd. 12 March, 1969 [26 Sept., 1968], No. 45809/68. Heading F4T. [Also in Division C7] A multi-orifice lance for the refining of steel includes a fuel supply conduit 14 leading to a number of pipes 23, each of which is located within an oxygen supply pipe 21 supplied by annular passageway 17, so that the fuel is entrained in a stream of oxygen. Pipes 21 are each provided with a Venturi 33 to accelerate the oxygen flow, and the fuel conduit preferably has an annular thermal insulation jacket between it and the oxygen supply.
