Nul warm warm water combined use die LPG air gas production plant

摘要

PURPOSE:To enable the change-over operation according to climate conditions and the like so as to allow liquefied petroleum gas to be vaporized desirably even in a cold district or in the coldest period by winding a heating tube, supplied with hot water therein, around the outer periphery of a supply side manifold. CONSTITUTION:A hot air-hot water combined type carburetor 1 is provided with a supply side manifold 2 and an exhaust side manifold 4, and numerous heat transfer tubes 6 are connected between both manifolds 2, 4. For further improvement in the heat transfer (heat absorbing) effect of the heat transfer tubes 6, heat transfer fins 8 are disposed around the heat transfer tubes 6. A heating tube 21 is wound around the outer periphery of the supply side manifold 2, and hot water is supplied into the heating tube 21. The ideal cross section shape is rectangular from the viewpoint of the contact area. Liquid used as hot water can be normal water, but ideal liquid is antifreezing solution mixed water mixed with an antifreezing solution. The change-over operation can be thereby performed according to climate conditions and the like, and liquefied petroleum gas can be vaporized desirably even in a cold district or in the coldest period.
