ABSTRACT:
A method and apparatus for improving the efficiency of a heat generator in which combustible fuels such as fossil fuels, refuse, or other materials are burned is described. Flue gas generated in the heat generator and combustion air are passed in heat exchange relationship in a heat exchanger. The heat exchanger is selected so that it removes 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 of H.sub.2 SO.sub.4 is likely to condense out. A pollutant removing liquid is applied onto the portion of the heat exchanger where the flue gas passes through both to scrub the flue gas and protect that portion of the heat exchanger from corrosive effects from condensed pollutants. Particulates and gaseous pollutants are removed from the flue gas and the heat exchanger by the liquid, which may be a neutralizing liquid such as an alkaline solution to provide a protective sheath for the heat exchanger against the effects of corrosive pollutants. In the described illustrative embodiment, the invention is shown in use with a thermal section for a large scale power plant.
