Kihlberg, Y R; Lagerquist, S G

An improved method of exchanging heat between combustion gases from combustion of fossil fuel with air and a fluid to be heated is obtained by initially introducing into the exhaust gases a volatile medium to be vaporized by said gases and subsequently condensing the vaporized medium by cooling the obtained mixture of combustion gases and vaporized medium to a temperature below the dew point. The cooling is performed by the fluid to be heated. The new method reduces the contents of polluting ingredients in the exhaust combustion gases and will keep the heat exchange structures clean.
