PROBLEM TO BE SOLVED: To provide a multistage pressure condenser combining miniaturization and the efficiency improvement of a power plant. SOLUTION: The temperature of low pressure side condensate 9 is efficiently raised with excellent heat transfer based on contact heat transfer in dripping in high pressure side steam, and turbulent heat transfer with circulating flow caused by flow-down condensate 19 falling by overflowing, and high pressure side condensate 8 joins condensate 20 in the state of keeping high temperature by bypassing the condensate 20 in a reheat chamber 11 by a by-pass connecting pipe 17. The low pressure side condensate 9 is sufficiently heated in the state of minimizing a falling space for miniaturization, and the condensate of high heat exchanger duty is fed to the condensate pump side to provide the multistage condenser combining miniaturization and the efficiency improvement of the power plant.
