<P>PROBLEM TO BE SOLVED: To provide an oxygen combustion type coal fired power generation system, capable of improving heat efficiency of the oxygen combustion type coal fired power generation system, and preventing corrosion of piping materials constituting a system of a fired power generation system, by suppressing the generation of condensate water and generation of acid in a combustion exhaust gas. <P>SOLUTION: In the oxygen combustion type coal fired power generation system, a heat exchanger 4 for temperature rise of oxygen, heating oxygen generated by an oxygen manufacturing device 12 by the combustion exhaust gas, is disposed in a combustion exhaust gas system; an oxygen supply system 14 for allowing oxygen to flow down, is disposed in a state of being connected to an exhaust gas system 15 for mixing from the oxygen manufacturing device 12 through the heat exchanger 4 for temperature rise of oxygen; the oxygen heated by the heat exchanger 4 for the temperature rise of oxygen is mixed with the combustion exhaust gas flowing down in the exhaust gas system 15 for mixing to prepare a support gas of a desired temperature; and the support gas is supplied to a coal boiler 1 through the exhaust gas system 15 for mixing. <P>COPYRIGHT: (C)2011,JPO&INPIT |
