PURPOSE:To obtain a high pressure mixed gas by forming a flare part at an inside surface of a connecting part of a mixer with a gas transport pipe, sucking and mixing air, and generating a spiral flow by utilizing a high pressure of raw gas ejecting from a slit at a periphery of the flare part. CONSTITUTION:A liquefied fuel in a storage tank 1 is introduced into a vaporizer 2 by a pump 2, regulated to 5-10kg/cm<2> by a pressure regulator 21 after it is gasified, and supplied from an annular slit into a mixer 7 through a primary fuel supply pipe 20 and a distribution chamber. A secondary gas, air, is sucked by utilizing a negative pressure generated in the mixer by an ejecting flow from the slit. A mixed gas formed is made to flow along the flare part 11 by Coanda effect due to the ejecting flow along the flare part 11, and forms necessarily a spiral flow in a transporting pipe 10. It is possible, as a result, to send the mixed gas to a holder 8 at a high pressure of about 1kg/cm<2> and to supply it to users only after pressure reducing regulations. |
