FIELD: oil and gas industry.SUBSTANCE: invention describes a structure of a biomass utilisation plant by means of gasification or pyrolysis, in which a vertical cylindrical reactor with a solid particle bed in its lower part, which is provided with devices for supply of biomass and medium under pressure to the solid particle bed, as well as devices for collection of combustible gasification products at the outlet in its upper part, located coaxially inside the annular reactor containing a layer of a granulated catalyst of complete oxidation in its lower part, and provided with a gas-distributing grid and devices for fuel and air supply to a catalyst layer, as well as devices for collection of combustion products, which are located in its upper part. To external surface of the internal reactor there welded are flat ribs from material of the reactor housing, and between branch pipes for supply of biomass and medium under pressure there arranged is a gas-distributing grid above which there located is an organisational head piece, a non-isothermal grid and a heat exchanger, and gaseous gasification products are supplied to the branch pipe for supply of medium under pressure. The lower part of the annular reactor is provided with particles of a catalyser of deep oxidation of substances mixed with disperse particles of inert material, and above the gas-distributing grid there located is the organisational head piece, the non-isothermal grid and the heat exchanger.EFFECT: increasing productivity as to utilised biomass.6 cl, 9 ex, 1 dwg |
