摘要： A process including an apparatus for use therein for gasifying a carbonaceous material by means of blowing said carbonaceous material onto a high temperature molten iron bath through a top-blowing lance of the non-immersion type is disclosed. The apparatus comprises a furnace body containing the high temperature molten iron bath, a top-blowing lance of the non-immersion type which is a multi-nozzle lance comprising a central nozzle for blowing the carbonaceous material in a powdery form, a plurality of inner nozzles for blowing a gasifying agent, the inner nozzles for blowing the gasifying agent being positioned surrounding said central nozzle, and another plurality of outer nozzles for blowing an oxidizing gas for secondary combustion of part of the product gas to maintain the molten iron bath temperature at a level high enough to continue the gasification, said outer nozzles being positioned surrounding said plurality of inner nozzles, the axis of each of said outer nozzles being inclined towards the outer periphery at an angle of 20.degree.-60.degree. with respect to the axis of said central nozzle, means for discharging the slag during gasification, and means for recovering the product gas.

摘要： A method of controlling independently of each other the stirring strength of a jet of oxygen gas and the flow rate of the oxygen gas to be blown onto a molten metal bath in a top-blowing oxygen furnace is disclosed. The method comprises providing an oxygen supplying conduit with a means of detecting the temperature of the supplied oxygen gas, a means of detecting the pressure thereof, and a means of heat-exchanging with the supplied oxygen gas, controlling the temperature and pressure of the oxygen supplied so that the stirring strength of the jet of oxygen gas and/or the flow rate of the oxygen gas are controlled independently of each other with the top-blowing lance being kept at a predetermined position.
