COGENERATION SYSTEM UTILIZING LNG CRYOGENICS

摘要

PROBLEM TO BE SOLVED: To establish a cogeneration system utilizing the LGN cryogenics which realizes remotely decentralized power source from an existing LNG plant facility, and dynamically feeds the power and the heat in an interlocking manner to an external load. SOLUTION: The cogeneration system X comprises an LNG storage tank 1 to introduce LNG from an LNG plant facility P, a vaporizer 2 which introduces LNG and generates the cryogenics and boil-off gas (BOG) or gaseous hydrogen, a micro gas turbine 3 which introduces the boil-off gas (BOG) or gaseous hydrogen, and performs the power generation and heat exhaust, an output 6 for thermal load which feed the thermal energy to an external thermal load (A) via a heat exchanger 4 for cold to perform the heat exchange by introducing a refrigerant absorbing the cold in a circulating manner and a heat exchanger 5 for exhaust heat collection to perform the heat exchange by introducing the exhaust heat, and an output 7 for power load which supplies the power to the external power load (A) by the power generation.
