Vaporized gas . Heating medium . Discharge . Heating medium regenerator (57) Abstract: The present invention relates to a leakage detection and prevention system for liquid a heater that is applied to a low temperature liquid pressurizing device which is used to pressurize or heat a low temperature liquid such as liquefied natural gas (LNG) or liquid petroleum gas (LPG) into a liquid or gas having higher pressure and temperature in order a to supply same to a place where high temperature gas is used. The present invention is capable of detecting the leakage of natural gas, and, in the event that the natural gas leaking, is the supply of a heating medium stopped is so as to prevent an accident that might result.
