PURPOSE:In a generating plant employing liquidized natural gas as fuel, to improve the entire efficiency by recovering heat for cooling lubricant, transformer and generator through thermal medium of exhaust heat recovery generating plant thereby reducing the heat loss. CONSTITUTION:In a power plant 1, liquidized natural gas 4 is employed for condensation of refrigerant then evaporated by high temperature cooling water 13. Condensed refrigerant 16 is gasified by high temperature cooling water 13 then used together with gasified natural gas to drive each turbine generator 18, 21. Natural gas from the turbine generator 18 is heated again by high temperature cooling water 13 and fed as fuel gas 5 to gas turbine, steam turbine combined power plant 2. Here the thermal medium 23 in the exhaust heat recovery power plant 23 is passed to a lubricant cooler 28, transformer heat recovery system 30 of the plants 1, 2 to recover heat in the plant 3. |
