摘要
A process and device are disclosed for utilizing the energy of flue gasses from coal-fired power stations in which the flue gasses are cleaned in a flue gas scrubber and guided into a cooling tower. The object of the invention is to allow energy content of flue gasses from coal-fired power stations to be ingeniously used even after the flue gasses have been washed in the washing tower, and thus also to use their wet fractions. For that purpose, the desulphurized flue gasses are cooled down to the water dew point in a mist collector known per se, before the flue gas outlet, and the perceptible latent heat thus withdrawn is used for preheating the machine condensate immediately after the machine condenser. The extraction steam known in the state-of-the-art is used in a first low pressure preheating stage to generate additional electric power and thus to increase the power generated by the power station.
