LIQUEFIED PETROLEUM GAS EVAPORATOR

PURPOSE:To vaporize LPG without generating drainage by annularly arranging heating mediums onto the outer periphery and allowing LPG to flow down and vaporize in a trunk pipe filled with heat exchanging fins inside and heating LPG during the time when LPG rises at a low speed from the lower part of a hollow pipe shaped accumulator. CONSTITUTION:An LPG evaporator A has heating mediums 9 arranged onto the outer periphery, and a hollow pipe shaped accumulator 14 having a communication port 13 is installed, penetrating in the vertical direction, in the lower part of a trunk pipe 1 filled with heat exchanging fins 2 in multistage form, and an introducing pipe 4 equipped with a liquid-amount adjusting valve 15 is installed continuously to the upper part in the trunk pipe 1. An outlet pipe 6 is continuously installed in the upper part of the accumulator 14, and a drain pipe 10 equipped with a drainage discharging valve 11 is installed in the bottom part of the accumulator 14.
