℃ steam, and this steam is supplied to the evaporator as a heat source. Then, the heat source steam gives heat to the working medium in the evaporator, evaporating the working medium, and condenses itself to 100°C.
This condensate is further used for preheating the working medium or cooled to 32° C. by passing it through an air cooler, and then supplied to the cooling tower as make-up water.
冷却塔において、この補給水は冷却水から蒸発潜熱を奪
って蒸発する。これにより３２℃の冷却水が得られる。In the cooling tower, this make-up water removes latent heat of vaporization from the cooling water and evaporates. This provides cooling water at 32°C.

置を提供するものである。In this way, the overall water balance can be achieved by cooling the heat source water that has been used as a heat source and using it as make-up water for the cooling tower, that is, the amount of heat source water that can be used as make-up water is If the amount evaporated in the cooling tower is w2 and the amount removed as mist at that time is W3, then W!
Since =w2X0.9, W3 =W1 xQ,
If it is 1, it will be possible to make ends meet, and therefore power can be generated even in places where there is no water. In this sense, the present invention provides a self-contained water generating binary power generation device that does not rely on an external cooling water source.
