PROBLEM TO BE SOLVED: To allow easy replacement of a cylinder while maintaining the supply of liquefied petroleum gas (LPG) similar to conventional one with natural vaporization. SOLUTION: To combustion equipment F, a stationary metal cylinder 10<SB>1</SB>and a replaceable cylinder 10<SB>2</SB>are connected via a gas meter M and a gas pressure regulator C so that gas pressure of a gas phase b in the replaceable cylinder is used for transferring fuel gas from the replaceable cylinder into the stationary cylinder. The metal cylinder is initially connected to the gas pressure regulator, and so gas similar to conventional one is supplied with natural vaporization in the metal cylinder as long as LPG is filled in the stationary cylinder. As the LPG is reduced with the gas supplied from the stationary cylinder, the LPG therein is transferred from the replaceable cylinder into the stationary cylinder. When the amount of the LPG in the replaceable cylinder is reduced, the cylinder is replaced with a cylinder in which LPG is fully filled. In this case, the replaceable cylinder which is formed of a resin or has reduced capacity and size is lighter and easier to replace. COPYRIGHT: (C)2009,JPO&INPIT
