EXPLOSION-PROOF GAS GENERATOR OF INVERTED GASIFICATION PROCESS Russian patent published in 2019 - IPC F23B99/00 F23G7/10 

FIELD: technological processes.

SUBSTANCE: invention relates to power technological equipment, namely to devices for thermal processing of solid fuel into combustible gas, and can be used for production of generator gas from wood chips. Explosion-proof gas generator of the reverse gasification process includes a gasifier housing, in the upper part of which there is a loading hatch, and in the lower part of the housing there is a gasification zone with tuyeres for air supply to the combustion zone, at that, the housing is installed on the base, where in upper part there are cavities of discharge of generator gas and on which grate is arranged, and in its lower part there is an ash hatch, loading hatch through lows is movably arranged on vertical bars fixed on gasifier housing, springs are put on rods, which are during operation of gasifier in compressed state and press hatch to upper edge of housing with seal, lower end of spring rests against eye of hatch, and upper in tension nuts, located on upper end of rods, with possibility at explosion of combustible gas lifting hatch and output of flue gas into atmosphere and pressure levelling in gasifier from atmospheric pressure and subsequent tight pressing, under effect of compression springs, to upper edge of housing.

EFFECT: invention allows maintaining gas generator in operating condition at unauthorized explosion of combustible gas in gasifier.
