<p>The invention relates to a device for cooling chimney-gases in such plants, where water, heated in a heating boiler, is supplied to heat consumers; e.g. radiators. According to the invention, a condensor-heat exchanger is arranged downstream of the heat consumers, a chimney gas cooler is situated in the chimney gas channel from the heating boiler, whereby said condensor-heat exchanger and said chimney gas cooler are parts of a closed cooling system, containing e.g. freon gas, together with a refrigerating compressor and a throttle.</p> |
