PURPOSE:To contrive to improve the thermal utilization efficiency of a system by a method wherein heat transfer medium for supplying heat is heated with the steam extracted from a turbine by means of a feed water heater arranged in a turbine system in a plant, which supplies heat energy simultaneously with electric power. CONSTITUTION:In the working example of a power generating system supplying heat energy at the same time for nuclear reactor, high temperature heat transfer medium heated at a nuclear reactor 110 is led to a heat exchanger 120 so as to heat the feed water sent from feed water heaters 140 in order to generate steam. The generated steam is led to a high pressure turbine 130 to drive it. Further, the steam left the turbine 130 is led through a moisture separator 170 to a low pressure turbine 130' to drive it. Finally, said steam is condensed at a condenser 150. Said feed water heaters 140 consist in arranging five stages ranging from high pressure stage to low pressure stage. The two feed water heaters 140' arranged on the low pressure side are used for supplying heat energy. Steam extracted from the low pressure turbine 130' is employed as the steam, which supplies heat to the feed water heaters 140'. |
