Publication number: 20240117759Abstract: A power generation facility in an embodiment includes: a boiler; a high-pressure turbine to which steam generated in the boiler is introduced; a low-pressure turbine provided downstream of the high-pressure turbine; and a condenser that condenses steam discharged from the low-pressure turbine. The power generation facility further includes: a feed pipe that leads feedwater in the condenser to the boiler; a heat storage and steam generation device that has a heat storage function that uses surplus energy generated in an own system to store heat, and a steam generation function that has part of feedwater led by the feed pipe introduced thereinto and turns the feedwater into steam by the stored heat; and a steam supply pipe that supplies steam generated in the heat storage and steam generation device to an own system.Type: ApplicationFiled: July 19, 2023Publication date: April 11, 2024Applicants: KABUSHIKI KAISHA TOSHIBA, TOSHIBA ENERGY SYSTEMS & SOLUTIONS CORPORATIONInventors: Hiromutsu MIKI, Keiko SHIMIZU, Hiroki SHIRAISHI, Yoshihiro IWATA, Yukitoshi OOTA
