Abstract: 台灣地區使用桶裝瓦斯的家庭約有 340 萬戶以上,數量遠高於天然氣 的家庭用戶,由於使用桶裝瓦斯會有存底殘液的問題,影響廣大消費者的 權益至深且鉅。本論文提出一種「瓦斯桶存底殘液之揮發研究」,主要設 有一帶體可圈繞於瓦斯桶身下方,帶體的兩端分別設有磁鐵,透過磁鐵吸 力可使帶體緊束固定。帶體的內側設有電熱元件,使用電線連接於電源。

There are more than 3.4 million households using liquid petroleum gas (LPG) in Taiwan, much more than the households using natural gas. The residuals of LPG in the bottom of cylinder have significant impact on the interests of consumers. This paper presents a "study on volatilization of the residuals in the bottom of LPG cylinder", featured with a belt around the bottom of cylinder. The belt is secured by the magnets on both ends of it. There is a heating element, which is connected to the power supply over power wires, in the belt. When the level of LPG reaches below a set point, the pressure drops and the residual liquid in the cylinder cannot be supplied to the stove for burning. The pressure rises when the heating element is powered on, which facilitates the full volatilization of residuals, so there is no residual liquid in the cylinder. The result of study shows that the average temperature (Tm) is increased to 43.9℃ from 25.2 , and the pressure to 10.23 kg/cm2 from 6 ℃ kg/cm2, up to 70.5%. The tests prove that the invention, the heating element, described in this paper, has remarkable impact on the pressure boosting in the LPG cylinder, and is very useful for solving the problem of gas residuals.
