摘要： A process for recycling hot dust from a gasifier or melt-down gasifier by means of a hot gas cyclone separator integrated into a pipe system is described, together with the associated apparatus. The hot dust from the hot gas cyclone separator is supplied by means of a lock system to a burner in order to overcome the pressure difference between the hot gas cyclone separator and the melt-down gasifier. By means of the lock system the dust is supplied from a lower pressure zone to a higher pressure zone. The dust to be recycled comprises coke or a mixture of coke and iron particles.

摘要： A process for producing pig iron is described, which contains a reducing shaft furnace 1 and a melting gasifier 2. The sponge iron produced from iron ores in the reducing shaft furnace is supplied to the melting gasifier and converted there into a pig iron melt. The gas produced in the melting gasifier is supplied directly via a line 4 as reducing gas to the reducing shaft furnace. The blast furnace gas passing out of the reducing shaft furnace, after traversing a CO.sub.2 scrubber 6, is at least partly heated in a heat exchanger to 200.degree. to 500.degree. C. and passed to a partial combustion plant 13 where, accompanied by the addition of oxygen, the gas is heated to the necessary reducing temperature.

摘要： A burner for the combustion of fine-grained to dusty solid fuels incorporates a central internal tube for supplying the solid fuels and an annular gap surrounding the internal tube and delimited by a cooled external tube, for supplying oxygen or oxygen-containing gas. The annular gap ends externally by an exhaust port directed obliquely relative to the longitudinal axis of the burner and peripherally surrounding the end of the central internal tube, or by a plurality of exhaust ports annularly disposed about the longitudinal axis of the burner. In order to ensure the complete combustion of the fine-grained to dusty fuels at a long service life of the burner, the inclination of the exhaust port(s) relative to the longitudinal axis of the burner is below 20.degree.. The exhaust port(s) is/are arranged transverse to the longitudinal axis of the burner and in the radial direction relative to the same at a distance of between 5 and 30 mm from the inner wall of the internal tube. The inclination of the exhaust port(s) relative to the longitudinal axis of the burner and the radial distance of the exhaust port(s) relative to the inner wall of the central internal tube are coordinated in a manner that the intersection of the extensions of the exhaust port and of the inner wall of the internal tube outside of the burner lies 20 to 80 mm in front of the burner mouth.

摘要： To gain electric energy in addition to producing molten pig iron, from lumpy iron ore and solid fuels, by using a direct reduction zone for the reduction of the iron ore to sponge iron and a meltdown-gasifying zone for the production of molten pig iron, carbon carriers are used in, and oxygen-containing gases are supplied to, the meltdown-gasifying zone. The reduction gas forming is fed into the direct reduction zone. The reduction gas reacted there is supplied as top gas to a power generation plant including a turbine. In order to adapt the power generation to the power consumption by simultaneously avoiding any influence on the metallurgical conditions at the production of pig iron and its further processing, the charge of carbon carriers into the meltdown-gasifying zone is varied as a function of the gas consumption of the power generation plant in a manner that, with a higher gas consumption, the volatile constituents of the charge are increased and the C.sub.fix charge is reduced and, with a lower gas consumption, it is proceeded the other way round, while keeping the amount and composition of the pig iron produced substantially constant.

摘要： There is disclosed a method and a melt-down gasifier for producing molten pig iron or steel pre-products and reduction gas. A first fluidized-bed zone is formed by coke particles, with a heavy motion of the particles, above a first blow-in plane by the addition of coal and by blowing in oxygen-containing gas. Iron sponge particles and/or pre-reduced iron ore particles with a substantial portion of particle sizes of more than 3 mm are added to the first fluidized-bed zone from above. A melt-down gasifier for carrying out the method is formed by a refractorily lined vessel having openings for the addition of coal and ferrous material, openings for the emergence of the reduction gases produced, and openings for tapping the metal melt and the slag. Pipes or nozzles enter into the meltdown gasifier above the slag level at at least two different heights.

摘要： A process for the production of pig iron from fine ore is described, in which initially the fine ore undergoes prereduction to a degree of metallization of preferably 65 to 75%. The sponge iron obtained is then melted down and under goes a final reduction. This process takes place in a melting cyclone 2, to which the sponge iron is supplied by means of a central opening 1 and into which are tangetially blown via a lateral opening 3 a carbon carrier, an oxygen-containing gas and optionally fluxes. As a result of the angular momentum produced, the sponge iron particles are deflected to the side and melted and finally reduced by the combustion gases of the carbon carrier. The molten iron collects in an iron bath 8. The gas produced in the melting cyclone is cooled from approximately 1500.degree. C. to approximately 800.degree. C. in a waste heat system 10, as well as by admixing cooling gas supplied via a line 11 and is then used for the prereduction of the iron ore.

摘要： A process for producing molten pig iron or steel raw material in which iron oxide-containing, preferably pre-reduced raw material particles are introduced from above into a fluidized bed formed from carbonaceous solid particles and an oxygen-containing carrier gas.

The fluidized bed receives additional energy through plasma heating, in such a way that the plasma energy is supplied level with the entry of the oxygen-containing carrier gas into the fluidized bed.
