SYSTEM FOR PRODUCTION OF SPECIAL PURPOSE GAS, DEVICE TO REMOVE HEAT AND ACID GAS ON ITS BASIS AND PROCESS OF PRODUCTION OF SPECIAL PURPOSE GAS Russian patent published in 1999 - IPC

FIELD: gasification systems. SUBSTANCE: reactor of gas generator carrying fluidized layer is heated to certain temperature limit either with the aid of external heater or by means of second fluidized layer located above first fluidized layer. Heat exchanger for indirect heating of corresponding fluidized layers can be positioned in first and/or second fluidized layers. Condensing heat exchanger removes heat from special purpose gas and condenses acid gas from it for re-circulation of chemical substances. Reagent to clean special purpose gas in injected into condensing heat exchanger. Increased pressure is formed in cleaned special purpose gas for its direct burning in turbine. System designed in accordance with invention is autonomous which means that it can operate under uniform mode without stoppage and re-starts. Low-temperature implementation of system prevents formation of melt and possible reaction between melt and water, diminished possibility of pollution and reduces need in cooling of vessel of gas generator. System is provided with heat and mass exchange surfaces resistant to corrosion on heating side and to scale formation. EFFECT: enhanced functional efficiency and reliability of system. 27 cl, 5 dwg
