UNDERGROUND CRYOGENIC GASIFIER Russian patent published in 2003 - IPC

FIELD: cryogenic equipment, particularly cryogenic gasifiers. SUBSTANCE: Gasifier comprises inner and outer shells, which define sealed chamber. Cryogenic liquid evaporators, aerodynamic heating turbine with drive and heating cell with closed loop are arranged in chamber. Inner shell has bubbler in form of block of perforated tubes. Block inlet end is connected by valve to feed pipeline. Gasifier has additional remote gasification board, which is fixed to common plate. Gasification board can be moved to active vent flow area. Gasification board input is connected by flexible metal pipe to shell with cryogenic liquid, gasification board output is joined to aerodynamic heating turbine drive. EFFECT: enhanced effectiveness of gasification process by improvement of heat removal conditions and reduction of power consumption per product unit. 2 cl, 4 dwg _
