<p>PURPOSE:To save energy by making use of the natural vaporization of propane gas, and by combining the liquefied propane gas in a container in which the pressure is maintained constant and the propane gas generated through a heating vaporizer. CONSTITUTION:When propane gas is transferred and supplied from a propane gas container 1 to a supply conduit 6, the liquefied propane gas starts being vaporized in a propane gas space 2 by its own heat capacity, and is transfered through a natural vaporization conduit 4. At this time, the first valve 9 and the second valve 10 are left opened, and the supply pressure is controlled to be constant by modulating the opening of the second valve 10 by a signal from a pressure control instrument 14. A reduction in the pressure in the propane gas space 2 as the temperature of the liquefied gas is lowered is checked by a pressure control instrument 13. The third valve is opened to let the liquefied propane gas in the liquefied propane gas space 3 to flow through the fourth valve 12 to a heating vaporizer 7 to be vaporized and transferred to the supply conduit 6.</p> |
