Definitions

  • the present invention relates to a liquid fuel burner, and more particularly to a burner which can directly supply a liquid fuel and which can self-gasify the liquid fuel and improve combustion efficiency.
  • the current burners use gas as fuel. Due to the convenience of mass acquisition and transportation, natural gas and liquefied petroleum gas are used as fuel. However, when this kind of fuel burns, it will produce a lot of carbon dioxide, which has a great impact on the current global warming. Because the fuel belongs to petroleum products, there is a tendency to dry up in the continuous exploitation of the oil source. Therefore, it is looking for a cleaner and more abundant. The fuel of production is an urgent task. With the current technology, it is necessary to obtain a large amount of clean fuel and easy to store. Only gas fuel is changed to liquid fuel. For example: Methanol is a clean liquid fuel and is a real renewable energy source. The carbon dioxide produced by combustion is only half of natural gas and liquefied petroleum gas, and has safety and economic characteristics.
  • methanol is liquid. When it is directly burned, it must be converted into a gaseous state and burned, and converted into a gaseous state. In the process, some heat energy is consumed first, so that sufficient heat energy (combustion efficiency) such as gas is not obtained. Therefore, even if methanol is used as a fuel, the cost is low, environmentally friendly, and carbon monoxide poisoning is not easy to occur, etc. It is not a substitute for using natural gas or liquefied petroleum gas as the main fuel. Summary of the invention

Description

液体燃料燃烧器 技术领域
本发明关于一种液体燃料燃烧器，特别是指一种可直接供应液体燃料并 可自行气化液体燃料及提升燃烧效率的燃烧器。 背景技术
现行之燃烧器， 皆使用气体为燃料， 由于考虑可大量取得与运输之方便 性， 皆以天然气及液化石油气为炊事燃料。 但， 此种燃料燃烧时会产生大量 二氧化碳， 对现今地球暖化产生极大的影响， 并由于该燃料属于石油产品， 在油源持续开采恐有干枯之虞， 因此另外寻找更干净及可大量生产之燃料是 刻不容缓的事， 以目前之技术， 要取得大量之干净燃料并易于储存， 只有将 气体燃料改为液体燃料， 例如： 甲醇是一种洁净之液体燃料， 且为真正之再 生能源， 而其燃烧后所产生之二氧化碳则仅为天燃气及液化石油气的一半， 并具有安全及经济之特性。
而， 一般使用甲醇作为燃料之炉具， 则通常受限于甲醇燃烧效率较差， 原因则在于甲醇均为液态， 直接燃烧时须先受热方能转换为气态而燃烧， 而 在转换为气态之过程中即需先消耗部分热能， 因此无法达到如瓦斯般产生足 够之热能 (燃烧效率）； 故而， 即使使用甲醇作为燃料之费用较低、 较符合环 保且不易发生一氧化碳中毒…等优良特性， 仍旧无法取代使用天然气或液化 石油气作为主要燃料。 发明内容
本发明者有鉴于上述液体燃料使用上热值较低， 燃烧时所产生之热量有 限之缺失，故而研发出一种火力 (燃烧效率)更胜瓦斯炉具之液体燃料燃烧器， 期能为减缓地球暖化作一分贡献； 故本发明包括有：
一底座， 其下方设置一电热器并连接一恒温器及一过热断电器， 其内侧 设有一点火棒及一感温棒； 上方环设一圆弧形第一流道， 由流道下方设一穿 孔连接母火管线到底座中央， 该底座中央设置一集热盘， 并于周围设数导热 杆与底座内壁相连， 又该底座内壁上设置数道喷火管路， 并连通喷火管； 另 该第一流道上并嵌设一环状之第一垫片， 其上设一第一透孔以供连通第一流 道。
一第一承接座， 固接于该底座上，其周圆环设一圆弧形第二流道， 该第 二流道上设置一第一连通孔， 该第一连通孔连通该第一透孔， 又该第二流道 上并嵌设一第二垫片， 该第二垫片上设置一第二透孔， 该第二透孔并连通该 第二流道。
一第二承接座， 固接于该第一承接座上，其周圆环设一圆弧形第三流道， 该第三流道上设置一第二连通孔， 该第二连通孔连通该第二透孔， 又该第三 流道上并嵌设一第三垫片， 另该第二承接座侧壁上贯穿该第三流道设置一注 入孔。
一顶盘， 固接于该第二承接座上， 其中央设置一穿孔。
一阻热环， 固接于底座上方内围， 并向上延伸至顶盘下方。
上述该第一承接座可依需求增加为两组以上， 以增加液体燃料于流道内 之流动距离， 达到气化、 增压之效果。
本发明具有下列之优点：
1.本发明所使用之液体燃料， 可于流道内即因受热而气化增压， 故于燃 烧时可提升热值及燃烧之效率。
2.本发明以常温常压下之液体燃料， 直接注入燃烧器内， 再经由流道气 化增压后喷出燃烧， 使用上较为安全。
3.本发明以液体燃料做为燃烧热源， 以甲醇为例， 在天然气瓦斯及液化 石油气将课征能源税及石油日益减少下，价格势必增涨，若改以第二能源 (此 以甲醇为例)为燃料，其气化增压后燃烧之热值与目前之天然气瓦斯及液化石 油气相当，但价格便宜又安全， 并能降低二氧化碳之产出量， 达到节能减碳、 环保之功效。 附图说明
