STORAGE TANK, INCLUDING A HEAT EXCHANGER, AND NATURAL GAS FUEL SYSTEM INCLUDING THE STORAGE TANK

摘要

PURPOSE: A storage tank, including a heat exchanger, and a natural gas fuel system, including the storage tank, are provided to prevent damage to a tank by controlling the inside pressure of the storage tank.;CONSTITUTION: A storage tank comprises a heat exchanger(400) and stores liquid natural gas. Nature gas vapor is saved in the upper layer area of liquid natural gas. The heat exchanger is formed inside the storage tank. The liquid natural gas of high pressure is supplied to a heat exchanger. The heat exchanger liquefies nature gas vapor by using the rapid expansion heat of high pressed liquid natural gas. The heat exchanger comprises an expansion valve(410) and a heat exchanger piping. The expansion valve is connected to a pressurizing device(300). The liquid natural gas of high pressure flows in an expansion valve.;COPYRIGHT KIPO 2012
