PURPOSE:To provide the high efficiency condenser system contrived to prevent the system from the attaching of sea creature by a method wherein the flow velocity inside of said condenser system is maintained at the flow velocity faster than the controlled velocity even when the amount of cooling water is reduced according to the lower load operation of said condenser, during the partial load operation except at the rated output point of the plant output power or the low load of said condenser at the starting operation test output power rising time and the like especially in the atomic power plant. CONSTITUTION:A connecting valve 12A is provided on a connecting pipe 11A which connects the outlet part of a pipe nest 2B and the inlet part of a pipe nest 2C, and similarly, a connecting valve 12D is provided on a connecting pipe 11D which connects the inlet part of a pipe nest 2D and the outlet part of a pipe nest 2E. When a cooling water inlet valve 8A of said pipe nest 2A is OPEN, a cooling water outlet valve 9A of said pipe nest 2A is CLOSE, a water chamber connecting valve 10A is OPEN, a water chamber connecting valve 10B is CLOSE, a cooling water inlet valve 8B of said pipe nest 2C is CLOSE, a cooling water outlet 9B of said pipe nest 2B is CLOSE, a connecting valve 12A is OPEN, a inlet valve 8C of said pipe nest 2C is CLOSE, and a cooling water outlet valve 9C of said pipe nest 2C is OPEN, then the cooling water from a cooling water pumps 5A, 5B, 5C is flowed in order through said pipe nest 2A, pipe nest 2B and pipe nest 2C, similarly, flowed through a pipe nest 2F, pipe nest 2E and pipe nest 2D. Accordingly, even when the amount of said cooling water is reduced down to the one third, the flowing velocity inside of said cooling pipe can be maintained at rated flow velocity. |
