<p>PURPOSE:To stably feed fuel gas upon sole power failure of an LNG terminal. CONSTITUTION:An LNG extraction pipe 7 connected to an LNG storage tank 10 is provided on the outlet port side of an LNG boost pump 2 for boosting LNG gas from an LNG terminal 1. LNG is reserved in the LNG tank 10. A pressurized carburetor 15 is provided in a circulation line 16 laid in the storage tank 10. Gaseous NG gasified by the carburetor 15 is returned into a gas phase part of the LNG storage tank 10 so as to pressurize the LNG. Thus pressurized LNG in the LNG tank 10 is gasified by an air heat type carburetor 19, and the gasified NG is led into a gas conduit 4 through a gas feed pipe 20, and is then fed into a power station 5. Even though the LNG boost pump 2 comes to a stop due to power failure, the LNG in the LNG storage tank 10 is pressurized, and is then gasified before it is fed into the power plant 5, thereby it is possible to stably feed gas.</p> |
