METHOD OF VORTEX GAS GENERATION AND/OR COMBUSTION OF SOLID FUELS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC C10J3/72 F23C7/02 F23G5/27 B04C5/08 

FIELD: oil and gas industry.

SUBSTANCE: method of fuel processing to produce combustion gases in a single controlled flow, creating four successive areas, in the first area fuel pyrolysis is ensured, and the start of the solid residues gasification begins; in the second area gasification is completed by increasing of the process intensity, and the vortex flow of the gas suspension passes to the area of conditioning, where by time holding and correcting air supply the necessary properties of the gas suspension are ensured, then the gas suspension by a special method passes to the stabilisation area, which ensures the stability of parameters of the gas suspension by the mutual compensation of pulsations of the gas suspension in the third and forth areas, by time holding and correcting the supply of air and/or steam to the first and forth areas of the vortex flow. Wherein ash circulation is performed through the entire vortex flow from the stabilisation area to the first area of pyrolysis and further through all areas of the vortex flow. The reactor for fuel processing forming the vortex flow in the first chamber and transforming in three successive chambers, and implementing in full scope the suggested method together with the use of heat of the reactor walls for heating of air feed to the reactor equipped with devices for ash transportation from the forth chamber to the special prechamber of the first chamber with a possibility of removal of these chambers ash partially or completely via gathering in a special accumulating tank.

EFFECT: invention controls fuel pyrolysis and gasification, and its combustion, and facilitates more complete recycling of the process heat and burning-out of the ash combustion substances, as well stabilisation of the necessary parameters of the produced gas and ash of the fuel at the reactor output.
