Solar thermal power generation facility, solar thermal power generation method, heat medium supply device, and heat medium heating device

摘要

A solar thermal power generation facility (10) which uses a heat medium that undergoes a phase change between a liquid phase and a gas phase. The solar thermal power generation facility (10) comprises: a first heating device (12) which heats the heat medium with solar heat that is a first heat; a second heating device (14) which increases the ratio of the gas phase in the heat medium by heating the heat medium with a second heat that is different from the solar heat after the heat medium has been heated by the first heating device (12); and a turbine power generator (18) which is driven by the heat medium that has been heated by the second heating device (14). The second heating device (14) is configured so that the heat held by another heat medium is used as the second heat for the purpose of heating the first mentioned heat medium.
