LNG HYBRID VAPORIZING POWER GENERATION DEVICE

PROBLEM TO BE SOLVED: To generate power by effectively utilizing exhaust heat of a normal pressure solid electrolyte fuel cell and LNG cold. SOLUTION: Normal pressure high temperature exhaust gas is introduced from the normal pressure solid electrolyte fuel cell 2 into a gas turbine 3. Back pressure of the gas turbine 3 is kept in negative pressure with compressors 6, 7. Suction air of the compressors 6, 7 is cooled by utilizing cold of LNG in coolers 8, 9 to enhance efficiency. Since the exhaust gas becomes normal temperature and atmospheric pressure, the exhaust gas is cooled to -100°C and lower by utilizing the cold of the LNG in an air direct cooling device 10, and effectively utilized as cold.
