GAS GENERATOR OF REVERSE GASIFICATION PROCESS Russian patent published in 2017 - IPC C10J3/20 

FIELD: oil and gas industry.

SUBSTANCE: gas generator includes a fuel hopper (1), a fuel lock chamber (2) operating under variable pressure, fuel lines (3) operating under pressure. There are branch pipes arranged in upper vertical part of the fuel lines (3) (4) for feeding blow air into a first combustion zone and a lance for collection of pyrolysis (5) gaseous products with their outlet gas lines to the upper part of the reactor (6). The reactor (6) is a vertical cylindrical vessel, the upper part of which is intended for post-combustion of pyrolysis vapor-gas products, the middle part is for semi-coke gasification, and the lower part is filled with "ash pillow"; a fire grate (7) is located in the lower part of the reactor. There are nozzles (8) and (9) designed for tangential air supply to the afterburning zone of steam-gas pyrolysis products and to the semi-coke gasification zone. An intermediate ash chamber (10) operates under pressure, and an ash gateway (11) operates under variable pressure. The lances (12) for collecting and diverting the generator gas are located in the lower part of the reactor. The hydraulic control system for the fire grate (7) and valves (13) for fuel (2) and the ash (11) lock chambers operate from a single oil station. The reactor (6) is made with a water-cooled casing with an output for generated steam into steam collector. The entire outer surface of the gas generator, including the fuel lines, the reactor and the ash portion are heat-insulated.

EFFECT: design of the gas generator makes it possible to increase its power, increase the efficiency of the gas generator and produce gas without resins, carbon black and hydrocarbons.
