摘要 |
The invention relates to a method and an installation, preferably in district heating plants, for condensing flue gases in the combustion of hydrogenous or moisture-containing fuels. The flue gases are subjected to an initial cooling in a flue gas condenser, which produces a condensate, and a subsequent cooling in a rotatable regenerative heat exchanger, having an air side, through which combustion air passes in one direction to the combustion plant and a gas side, through which the flue gas from the combustion plant passes in an opposite direction. The condensate (10), from the condenser (13), is supplied to the regenerative heat exchanger (16) and is sprayed on the air side (21) in the form of a water mist and is collected and guided to the sewage system from the inlet part of the air side (21) and/or the outlet part of the gas side (22) of the heat exchanger. <IMAGE> |
