<p>PURPOSE:To obtain an efficient and a constant-discharge pressured delivery in an LPG gasification equipment by recirculating a portion of gasified high pressure gas through a gas turbine motor for a booster pump, while regulating its flow rate. CONSTITUTION:Liquefied gas from an LPG tank 1, whose internal pressure varies depending on the external temperature, is sent to an LPG vaporizer 5 after it is pressed up to the prescribed pressure by a booster pump 3. The high pressure gas gasified here is supplied to a gas turbine generator 7 via a flow-control valve 6. A portion of the high pressure gas is returned to a gas turbine motor 10 via a flowcontrol valve 9, and its driving force is connected to the booster pump 3. This contrivance obtains a more efficient means than the use of electric power from a generating equipment in which liquefied gas is used as fuel. It also obtains a constant discharge pressure at the booster pump 3.</p> |
