Abstract (en)
[origin: EP0079648A1] 1. Steam power plant comprising an intermediate cooling circuit (1) which operates independently of the working medium and of the condenser coolant (17) of the main circuit (12) and in which an intermediate coolant flows in a closed circuit through the plant components (2, 3) to be cooled and an intercooler (7) charged with a secondary coolant (19) and an additional regenerative neat exchanger (8) is connected into the intermediate cooling circuit (1), in which heat exchanger the intermediate coolant transfers its heat to the working medium of the main circuit (12), characterized in that the regenerative heat exchanger (8) is connected in parallel with the intercooler (7), a controllable three-way mixing valve (5) being provided for the quantitative distribution of the intermediate coolant heated in the plant components (2, 3) to intercooler (7) and regenerative heat exchanger (8), and, in addition, the temperature (11) of the intermediate coolant being used as control parameter after completed heat transfer, recombination and mixing of the two part flows upstream of the components (2, 3) to be cooled.
