When a Combined cycle power plant was started, Steam turbine wasted pure water too much during prewarming of turbine. Wasted pure water gathered in vessel tank and evaporated immediately, then emitted atmosphere. We investigate method to recover the heat in vessel tank. We installed a heat exchanger in vessel tank. In this study, the designing and manufacturing procedures of the heat exchanger was presented. Also, the performance results was showed briefly.
