LIQUEFIED GAS VAPORIZER

PROBLEM TO BE SOLVED: To solve the problem that a conventional liquefied gas vaporizer uses an electric heater as a heat source so that it is difficult to secure its power supply. SOLUTION: The liquefied gas vaporizer is provided with a liquefied gas container 11 for accommodating a liquefied gas, a liquid phase take-out pipe 13 for taking out the liquid phase part of the liquefied gas from the liquefied gas container, a heat exchanger 14 for vaporizing the liquefied gas that is taken out of the liquid phase take-out pipe, and a catalyst combustor 16 for heating the heat exchanger by catalyst combustion. Since the catalyst combustor 16 receives the liquefied gas that is vaporized by the heat exchanger 14 as fuel, the catalyst combustor 16 can be installed at a location without any commercial power supplies, uses a combustion catalyst without any flame as a heat source and hence does not require any embers for improved safety, is simple in terms of structure, and is compact.
