PURPOSE:To attain power saving and substantial noise reduction on a blower etc. by detecting the temp. of generated gas in an evaporator and maintaining air feed on an appropriate level at all times. CONSTITUTION:LPG in a storage tank 1 is transferred through a strainer 2, an abnormal pressure preventing valve 3 and a vaporizing pressure control valve 4 into an evaporator 5. When the LPG flows down in the evaporator 5, evaporation occurs. Drain in the gas generated by the evaporation is removed by means of a mist separator 6, and the temp. thereof is elevated by means of a heater 7. The heated gas is fed through a cushion chamber 8 and a header 9 into a gas pressure control valve 10, wherein pressure control is performed. Thereafter, the gas is fed to a burner etc. In the above, the feed of air to a blower or a suction fan 14 is made automatically controllable in accordance with a change in the temp. of generated gas. As a result, it is possible to reduce an unnecessary power consumption by the blower or suction fan 14, i.e. to attain energy saving, and simultaneously to alleviate the occurrence of complaints to noise in the summer season wherein atmospheric heat is high and the opening of windows etc. is high. |
