DEVICE FOR GASIFICATION PF CARBON-CONTAINING FUEL, TREATMENT RESIDUE AND WASTE (VARIANTS) Russian patent published in 2002 - IPC

FIELD: fuels. SUBSTANCE: invention relates to device for gasification of carbon-containing and ash fuels, residues of their treatment and waste in the presence of oxygen-containing oxidizing agent at temperatures exceeding melting point of inorganic components. Device is made as reaction chamber of flow-type reactor under pressure from normal to 80 bars but preferably from normal to 30 bars. Reaction chamber is limited by cooling reactor wall that has jacket able to sense for pressure, cooling wall, water-cooling gap between jacket and cooling wall, ceramic protective cover of cooling wall and slag layer which are arranged in-line by direction externally/inside. Pressure and temperature of cooling water in cooing gap values are regulated so to provide temperature of cooling water lower or above its boiling point and pressure in cooling gap would exceed pressure value into gasification chamber. Invention describes also the device for gasification of carbon-containing ash-free fuels, residues of their treatment and waste in the presence of oxygen-containing oxidizing agent at temperatures above 850 C in reaction chamber made as flow-type reactor under pressure from normal to 80 bars but preferably from normal to 30 bars. Reaction chamber is limited by cooling wall of reactor that has jacket able to sense for pressure, cooling wall, water-cooling gap between jacket and cooling wall, ceramic protective cover of cooling wall and refractory lining which are arranged by direction externally/inside. The gap between jacket and cooling wall filled with water under pressure is made by so manner to make in it working conditions providing temperature of cooling water would lower or above its melting point. Pressure in cooling gap is maintained on the level exceeding pressure in gasification chamber. The use of invention ensures to develop simple and safety device that ensures to process fuels and waste with ash content modulating in the most wide limits. EFFECT: valuable properties of device. 8 cl, 2 dwg
