PURPOSE:To surely prevent the emission of liquid LPG when a liquid level in an evaporation chamber is abnormally increased, by providing between an LPG storage tank and the evaporation chamber a chamber for use in detecting a liquid level in the evaporation chamber. CONSTITUTION:A chamber 2 for use in detecting a liquid level in an evaporation chamber 3 is provided between a storage tank 1 for a normal-temperature liquefied gas and the evaporation chamber 3 for use in evaporating the mentioned gas. A liquid outlet of the storage tank 1 and the chamber 2 is communicated with each other via a pipe provided with a liquid pressure reducing valve 13. Also, a bottom portion of the chamber 2 and a liquid inlet of the evaporation chamber 3 are communicated with each other via a liquid pipe 6. Gas outlets of the chamber 2, 3 are communicated with a gas heating chamber 4. The chamber 2 is adapted to detect an abnormal increase in the liquid level in the evaporation chamber 3 to prevent LPG from flowing thereinto. Thus, the emission of the liquid LPG can be prevented. |
