<p>PURPOSE:To obtain the preheating effect of the liquefied gas at low temperature without using a preheater by allowing a portion of the liquefied gas heated close to the boiling point to circulate and mixing said gas with the liquefied gas supplied at a low temperature. CONSTITUTION:The LPG stored in a tank 1 at low temperature is supplied by a pump 2 and heated close to the boiling point in an evaporator 6, and the temperature is raised. Said gas is sent into the evaporator 6, mixed and preheated with the LPG extracted by a circulation pump 3. Therefore, preheating effect can be obtained without installing a heat exchanger, and cost can be markedly reduced.</p> |
