Abstract
A method and apparatus for improving the efficiency of the thermal section of a large scale power plant heat generator in which combustible fuels such as fossil fuels, refuse or other materials are burned are described. Flue gas generated in the heat generator and combustion air are passed in heat exchange relationship at diametrally opposite sides of a rotary type air preheater. The heat exchange relationship is selected so that it causes removal of a substantial amount of heat from the flue gas whose temperature is consequently lowered to a level where a corrosive pollutant such as SO.sub.3 in the form H.sub.2 SO.sub.4 condenses out. The heat exchange elements of the rotor are sized so that the cross-sectional area of the passages therebetween are small enough to prevent the formation of aerosols of sulfuric acid.
