Abstract
A multi-pressure condenser has first and second condensers with vacuum pressures. The second condenser has a higher pressure. The first condenser has a first cooling water tube bundle, and a pressure barrier which extends below the first cooling water tube bundle. A heat-transfer tube introduces fluid from outside the first condenser into the first hot well below the barrier. Liquid is dropped into the first hot well through the through holes of the pressure barrier. The second condenser has a second cooling water tube bundle. Condensate generated in the high-pressure chamber is accumulated below the second cooling water tube bundle. The multi-pressure condenser further has a steam duct to connect the gas phase parts of the first hot well and the second condenser, and a pipe to communicate the liquid phase parts of the first hot well and the second condenser.
