Steam power plant with a cooling system

摘要

In a steam power plant (1) a the first cooling circuit (101) comprises a condenser (6) to condense (4A, 9A) steam and a first pump (16) to pump a first cooling fluid (15) through the condenser (6) in order to cool the condenser (6), a the third cooling circuit (PGB) is a closed cycle cooling circuit that utilizes a second cooling fluid (27) to cool down at least one component that is different from the condenser (6), and a second cooling circuit (PCB) comprises a heat exchanger (26) that thermally couples the first cooling fluid (15) and the second cooling fluid (27) and utilizes the first cooling fluid (15) in the heat exchanger to cool down the second fluid (27) and comprises a second pump (44) to pump the first cooling fluid (15) through the second cooling circuit (PCB) independently from an operation of the first pump (16).
