TWO-STAGE GAS GENERATOR Russian patent published in 2022 - IPC C10J3/02 C10B53/02 

FIELD: heat and power, metallurgical and chemical industries.

SUBSTANCE: invention relates to heat and power, metallurgical and chemical industries and can be used to produce generator gas from solid carbonaceous fuel. The claimed two-stage gas generator, simultaneously operating in the mode of the direct process of gasification of solid carbon-containing fuel and in the mode of the inverted process of gasification of the resulting coke residue, contains a device 1 for supplying solid fuel, a device 2 for supplying a gasifying agent, a nozzle 3 for injecting additional steam, a housing 5 with an internal partition 4, a steam-water collector 6, a device 7 for the output of the resulting generator gas, a movable two-section grate 8 and a bunker 9 for ash and slag, as well as the necessary connections between them.

EFFECT: improving the quality of the resulting generator gas by reducing the corresponding concentrations of volatile resinous substances and fine particles of solid carbon-containing fuel in it.
