TEMPERATURE ELEVATION TYPE TERRESTRIAL BINARY POWER-GENERATION SYSTEM

摘要

PURPOSE:To improve the power generation efficiency and prevent eduction of silica scale by installing an absorption type heat pump and a heat exchange system etc. in which the temperature of the binary power-generating thermal medium is increased by the hot water in a system consisting of a steam turbine, generator, and a condenser. CONSTITUTION:The terrestrial water 300 ejected from a production well 10 is introduced into the evaporator 1,010 in a dilution part 1,000 and used for evaporating thermal medium 400, which is introduced into an absorbing device 1,020, and brought into contact with the concentrated absorbing liquid 500 to be condensed. In this case, the concentrated absorbing liquid 500 is heated by the generated dilution heat and the thermal medium 200 which flows in the absorbing device 1,020 and drives a turbine is heated, and then introduced into a turbine 100. The terrestrial water is introduced into a regenerator 1,110 and heats the absorbing liquid 510 which is diluted in the absorbing device 1,020, and the evaporated thermal medium is introduced into a condenser 1,120 in which the vapour is condensed. On the other hand, the thermal medium 200 having an increased temperature is introduced into a heat exchanger 1,300 and the absorbing device 1,020, heated further there, and then introdued into a turbine as vapour.
