摘要： In an oxygen mixer for an oxygen combustion boiler, circulating exhaust gas 8a heated in a rotary preheater 11a is mixed with oxygen. Resultant mixed gas 4 is guided to a boiler furnace 1 through a combustion gas duct 3 having bends 21a, 21b and 21c. At the bend 21a closest to the rotary preheater 11a in the combustion gas duct 3, an oxygen injection nozzle 23 is arranged to have a plurality of injection ports 26 for injection of oxygen 22 into circulating exhaust gas 8a.

摘要： In an oxyfuel combustion boiler system, nitrogen gas 4 separated by an air separation unit (ASU) 1 is supplied as carrier gas to a pulverizer 5 for drying and pulverization of fuel 6. A fluid mixture 22 of the nitrogen gas 4 from the pulverizer 5 with pulverized fuel 21 is supplied to a powder separation device 24 where the pulverized fuel 21 is separated. The separated pulverized fuel 21 is mixed with the primary recirculated flue gas 16 and supplied to a burner 8.

摘要： Gasification of carbon-containing raw material into gasified gas and recovery of CO 2 are enabled at the same pressure throughout a system. Provided are a hydration tower 1 for performing hydration reaction by contact of CaO with water vapor while keeping at a predetermined pressure and a temperature at or below an upper limit for production of Ca(OH) 2 ; a gasification reactor 2 with a water removal section 2a for dehydration of Ca(OH) 2 introduced through heating to obtain highly active CaO and with a gasification section 2b for production of char through reaction of a raw material with water vapor and production of gasified gas through gasification of the char, CO 2 being absorbed by CaO from the section 2a to produce CaCO 3 , heat of reaction at that time being used for the gasification of the raw material, the gasified gas being used as a heat source for the dehydration in the section 2a; and an absorbent regeneration tower 3 in which, in the presence of the char-containing CaCO 3 from the section 2b, CO 2 , water vapor and oxygen, CaCO 3 is calcined with heat of combustion of the char to separate it into CO 2 and CaO, the resultant CaO being supplied to the hydration tower 1. The pressure in the reactor 2 and in the tower 3 connected to the tower 1 is the same as pressure in the tower 1.
