A coal fired oxy-fuel boiler power plant has a combustion system configured to burn coal using an oxygen stream to produce a flue gas stream. A CO_2 capture system is connected to the flue gas stream and a steam cycle with serially arranged low pressure heaters forming a part of a condensate system. The combustion system comprises an air separation unit for removing N_2 from air to produce the oxygen stream for a boiler. The air separation unit comprises an air separation unit heat exchanger which is thermally and fluidly connected to the condensate system to be fluidly parallel to at least one serial low pressure heater and fluidly parallel to a number of the serial low pressure heaters which is at least one, but less than a total number of the serial low pressure heaters. A flue gas heat recovery system, a flue gas condenser, and a gas processing unit are thermally integrated into the condensate system. |
