METHOD FOR THE RECOVERY OF PROCESS WASTEWATERS OF A FOSSIL-FUELED STEAM POWER PLANT AND FOSSIL-FUELED STEAM POWER PLANT

摘要

The present invention relates to a method operating a thermal steam power plant (1), and a water-steam-circuit (2), a cooling water circuit (6) and the flue gas purification system (8) and the cooling tower ( 7) it relates to the one-fired steam power plant (1) having a. Fired steam generator (3), steam turbine (4) and the condenser (5) is the water - is connected into the circuit (2) and steam. A cooling tower (7) and condenser (5) is expanded vapor is water-vapor-from the circuit (2) through a heat exchange with the cooling water circuit to be condensed in the condenser (5), in said cooling water circuit (6) It is connected. Flue gas from the fired steam generator (3) are cleaned in flue gas cleaning system (8), for this purpose, water is supplied to the process (9) is the flue gas purification system (8). Process waste water (10) is outside the flue gas purification system (8). According to the present invention, the flue gas purification system (8) can be extracted from the cooling water circuit (6) being connected with the flue gas purification system (8) the process water coolant circuit (6) required for. In addition, flue gas cleaning system 8 has been for the release of contaminated process waste water (11), connected to the waste water treatment system 13 including the evaporator 12 and, through the waste water treatment system, purified process waste water ( 14) it may be formed. ;
