GASIFICATION METHOD OF SOLID FUEL, AND ONCE-THROUGH GAS GENERATOR Russian patent published in 2012 - IPC C10J3/66 C10J3/74 C10B49/06 C10B53/02 

FIELD: machine building.

SUBSTANCE: method is implemented in once-through gas generator containing fuel bunker 14 for fuel subject to gasification, and at least one combustion chamber 32 by means of pyrolysis, at which fuel is decomposed into pyrolysis products, and further gasification, at which pyrolysis products are gasified to gas. Heat transfer from combustion chamber to fuel bunker is restricted to reduce the fuel heating before the beginning of pyrolysis stage using cooling channel 18 for movement of such medium, as gasification air. Upper surface of cooling channel 18 is formed with upper covering 16a of once-through gas generator, above which fuel bunker 14 is arranged, and lower surface is formed with lower covering 16b of once-through gas generator, under which combustion chamber 32 is located.

EFFECT: invention allows preventing heat transfer from combustion chamber to fuel bunker.
