摘要: 
本文研究主旨為:一、評估未來液化天然氣之發展趨勢。二、提升
燃氣爐具之熱效率。
台灣地區天然氣產量始終供不應求,一直到1990年自國外進口液
化天然氣(LNG)後,此現象才得以紓緩。未來,我們當可效法先進國
家的作法,好好地利用LNG的優越特性,發展天然氣發電、天然氣汽
電共生、天然氣冷凍空調、天然氣汽車、空氣液化分離、石化原料提
煉等高附加價值的工業,以提升我國的科技水平並改善日益惡化的環
境品質。
瓦斯爐有一定的燃熱範圍,不同類別或不同成份的瓦斯,可能無
法適用同一爐具。本文實驗乃採用CNS3101作為規範,以液化天然氣
為燃料,探討其是否可適用於一般天然氣及液化石油氣瓦斯爐?實驗
結果顯示:只要將噴嘴口徑適度修正即可適用,惟其熱效率偏低。經
測試瓦斯爐各項參數,得到一重要結論:影響熱效率的最主要參數為
焰孔之角度及爐架之高低。如將這兩項參數搭配妥適,必可提升瓦斯
爐之熱效率,達到節約能源之目的
台灣地區地狹人稠,實不宜發展核電。未來,以純凈低污染的液
化天然氣發電,取代高污染性的燃煤及高危險性的核能發電,將是不
可避免之趨勢。除此之外,液化天然氣的其它應用科技,亦會逐漸在
國內生根。

The purpose of this research is to evalute the formative tendency of LNG in future and elevate the efficiency of domestic gas burner.
The yield of nature gas is often shortage in Taiwan. The phenomenon had been released until 1990 that beacause of our country import liquefied natural gas from outland. Hence, we can develop natural gas powerhouse, compressed natural gas car, LNG cold energy utilization and LNG air-conditioning etc. That can promote our technology level and amend perversive environment.
Much fundamental theory in combustion and burner design for domestic natural gas appliances has to discuss relevant definitions and some basis combustion chemistry. This thesis considers the fundamental aspects of the four main components of the bunsen burner, that is the injector, air entrainment, mixing tube design and burner port geometry.
The use of natural gas as a fuel has increased dramatically throughout the world during the last thirty years. In Taiwan, the natural gas has been a marked rise in both the number of customers and annual gas consumption. Gas combustion research has played a key role in this rapidly expanding market, particularly with respect to design high efficiency of natural gas appliance.
