A coal fired power plant includes the catalytic reduction of NO.sub.x in the flue gas and the catalytic oxidation of SO.sub.2 to SO.sub.3 followed by the hydration of the SO.sub.3 to H.sub.2 SO.sub.4 vapor and then the condensation to H.sub.2 SO.sub.4 liquid. The condensation takes place in a wet sulfuric acid condenser by heat exchange with incoming combustion air. A portion of the heat picked up by that combustion air is used to provide a portion of the heat for the condensate from the steam turbine. The combustion air is then fed to an air preheater and to the steam generator as primary and secondary combustion air.
