    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: A thermal shielding for covers and bottoms of gas generators and other reaction vessels intended to operate at elevated temperature and pressure is disclosed wherein the cover or bottom comprises an extension, integral with the reaction vessel, with an outer closure supporting a plurality of spaced guide tubes having fluid jackets at the inner ends thereof, the fluid jackets of a plurality of circumferentially spaced guide tubes being interconnected by concentrically spaced heat transfer tubes substantially aligned with the inner surface of the reaction vessel, the fluid jacket of one of said guide tubes being divided by baffle means into separate chambers respectively connected with supply and discharge lines for cooling fluid to be circulated through said plurality of fluid jackets and concentric connecting tubes whereby effective cooling is achieved at inner ends of said guide tubes with a minimum of congestion externally of the vessel cover or bottom. In instances where there is need for a guide tube centrally of the cover or bottom, such guide tube has a fluid jacket at the inner end thereof which closely engages fluid jackets of the circumferentially spaced guide tubes and is provided with separate supply and discharge lines for cooling fluid. The space surrounding the guide tubes between the outer closure and heat transfer tubes is preferably filled with heat insulating material.

    摘要: An apparatus and process for regenerating a liquid from a spent liquid containing sodium compounds created during kraft processing for pulping wood while simultaneously obtaining energy. Regeneration begins by gasifying said sodium compounds in a gasification reaction chamber at a temperature greater than the melting temperature of the sodium compounds and generating a gasification gas and salt melt. The gasification gas and salt melt are then directly cooled to a temperature greater than the dew point in the quenching chamber by spraying a cooling liquid which, in turn, causes gaseous condensate to form a bath in the quenching chamber which may also include water from kraft processing. The salt melt dissolves in the bath to produce an aqueous solution. This aqueous solution is then cooled and diluted with alkali liquid produced during the kraft process. Then the diluted aqueous solution is subjected to flashing and emerges as a regenerated liquid free of organic components to be used again in the wood pulping process. Simultaneously, the gasification gas from the quenching chamber is indirectly cooled thereby producing energy through at least one of steam and hot water and subsequently desulfurized.
