    摘要: An apparatus for gasifying coal dust has a housing provided with an output fitting for the removal of generator gas and an output fitting for the removal of granulated slag. An overflow maintains a body of liquid in the bottom of the housing and a coal-dust burner in the housing forms a downwardly moving coal-dust flame in an upper reaction zone of the housing. An annular tube wall in the housing upper and lower ends where its tubes are bent apart and form radially throughgoing upper and lower openings and at the burner and therebelow but above the generator-gas output fitting. This tube wall is radially gastight between its upper and lower openings and radially inwardly delimits an axially extending annular passage that is outwardly defined by the housing. Steam is fed to the upwardly directed lances in the passage to create in the housing a toroidal annular current of moving gas and steam rising in the passage and descending in the zones between the flame and the tube wall. A coolant is circulated in the tube wall to cool the current of gas to below the softening temperature of any slag in the flame.

    摘要: An apparatus for gasifying pulverized coal, the apparatus comprising a housing with a granulated slag discharge opening in a bottom of the housing, and a producer gas outlet opening in a lower part of the housing; a layer of thermal insulation lining the housing; a pulverized coal burner having a discharge area in the top of the housing; a layer of heat-resistant lining located above the producer gas outlet opening; a steam injection inlet; and a plurality of ducts arranged between the heat-resistant lining and the thermal insulation and extending between the steam injection inlet to the discharge area, each of the ducts having an outlet opening arranged at a level of the discharge area and an inlet opening arranged above the steam injection means. Steam is injected into the housing and the producer gas is cooled with a plurality of cooling medium supply nozzles arranged in the housing.
