Abstract:
An air-heated/hot-water type vaporizer comprising:a supply-side manifold, a discharge-side manifold, and a plurality of heat transfer tubes having ends on one side connected to said supply-side manifold and ends on the other side connected to said discharge-side manifold;said supply-side manifold having a liquefied gas tube to which the ends on one side of said heat transfer tubes are connected and which is supplied with liquefied gas, and at least one hot water tube with a double-pipe structure, which is arranged in said liquefied gas tube and which is supplied with hot water;said hot water tube having an inner tube having an end connected to a hot water source and the other opening end, and an outer tube having an opening end through which said inner tube is inserted inward and the other closed end;said hot water supplied from said hot water source to said inner tube flowing in said inner tube, and flowing out from the other end thereof to the closed end side of said outer tube, the hot water having flowed out to the closed end side of the outer tube flowing through an annular path formed by said inner tube and said outer tube in the direction counter to that of the hot water flowing in said inner tube, and discharged from the opening of said outer tube to the outside; andsaid liquefied gas supplied to said liquefied gas tube flowing outside said outer tube and being heated by the hot water flowing through said hot water tube and vaporized.
