Abstract
Description
本發明有關一種燃燒系統及其運轉方法。The invention relates to a combustion system and its operating method.
現今的燃燒裝置,例如用於營造空間氛圍壁爐,大多以乙醇基燃料作為燃料,其為一種高度易燃的液體,在填充過程中可能導致爆炸或燒燙燒等風險,尤其是在壁爐完全熄滅或充分冷卻前填充燃料的風險更是特別高。另一個風險發生在壁爐意外傾倒時,乙醇基燃料將使火勢迅速蔓延。雖然異丙醇也經常用作燃料,但其仍具有與乙醇基燃料相似的缺點。Today's combustion devices, such as fireplaces for ambience, are mostly fueled with ethanol-based fuel, which is a highly flammable liquid that can cause risks such as explosion or scalding during filling, especially if the fireplace is completely extinguished Or the risk of refilling fuel before cooling down sufficiently is particularly high. Another risk occurs when the fireplace is accidentally toppled over. Ethanol-based fuel will allow the fire to spread quickly. Although isopropanol is also often used as a fuel, it still has similar disadvantages as ethanol-based fuels.
目前發現使用丙二醇基燃料可以克服上述問題。丙二醇基燃料包含至少60 wt%的丙二醇並具有至少高於50℃的閃燃點,根據調配比例,其閃燃點甚至可以高達104℃。因此丙二醇基燃料實際上是一種不易燃但可燃的液體燃料,「不易燃」是指在室溫下與火焰(如火柴)接觸時不會著火,「可燃」是指可以在適當條件下燃燒。而且,丙二醇基燃料燃燒時,傾倒在同環境溫度的表面上就會熄滅,避免火勢蔓延。It has now been found that the use of propylene glycol based fuels can overcome the above problems. Propylene glycol-based fuels contain at least 60 wt% propylene glycol and have a flash point at least above 50°C, and can even be as high as 104°C depending on the blending ratio. So propylene glycol-based fuel is actually a non-flammable but combustible liquid fuel. "Non-flammable" means that it will not catch fire when it comes into contact with a flame (such as a match) at room temperature, and "flammable" means that it can burn under the right conditions. Also, when propylene glycol-based fuel burns, it will extinguish when poured on a surface at the same ambient temperature, preventing the fire from spreading.
對於燃料來說,用於點燃的燈芯是必不可少的,通過毛細效應使上述的燃料通過燈芯傳輸。燈芯可以例如由玻璃纖維、陶瓷纖維材料、矽酸鹽纖維材料或岩棉,或聚合材料如芳香族聚醯胺纖維、棉或多孔材料如浮石、或本領域已知的其他燈芯材料所製成。其中,金屬燈芯相較於其他材料製成的燈芯於燃燒時不會產生碳化及耗損,且更適用於使丙二醇基液體燃料燃燒完全。然而,金屬燈芯具有因金屬導熱性佳而過熱影響火焰規模以及使熱量由燄端傳至燃料的問題。A wick for ignition is essential for the fuel, through which the aforementioned fuel is transported by capillary effect. The wick may for example be made of fiberglass, ceramic fiber material, silicate fiber material or rock wool, or a polymeric material such as aramid fiber, cotton or porous material such as pumice, or other wicking materials known in the art . Among them, compared with wicks made of other materials, the metal wick does not produce carbonization and wear when burning, and is more suitable for completely burning the propylene glycol-based liquid fuel. However, metal wicks have the problem of overheating affecting the size of the flame and heat transfer from the flame end to the fuel due to the good thermal conductivity of the metal.
此外,當火焰熄滅時,燈芯和燃料仍然很熱,這表示燃料正在蒸發而產生具有毒化學物質的廢氣。雖然丙二醇基燃料是一種具有低煙毒性的燃料,但即使是最少量的有毒化學物質也會使燃料產生有害人體健康的疑慮,因此仍需尋求解決方案,因為燃燒裝置需要能夠在具有兒童和孕婦的環境中使用。Also, when the flame goes out, the wick and fuel are still hot, which means the fuel is evaporating, creating exhaust with toxic chemicals. Although propylene glycol-based fuel is a fuel with low smoke toxicity, even the smallest amount of toxic chemicals raises concerns about the fuel being harmful to human health, so solutions are still needed, as the combustion unit needs to be able to operate in the presence of children and pregnant women. used in the environment.

請參照圖1與圖2,為本發明燃燒系統一實施例的外觀示意圖及部分剖面示意圖。本實施所示的燃燒系統,使用至少90 wt%丙二醇基液體燃料,燃燒系統包括一第一燃料槽10、一第二燃料槽20、一管路30以及一驅動單元40。第一燃料槽10供容納丙二醇基液體燃料並插置有一可傳輸丙二醇基液體燃料的金屬燈芯11。第一燃料槽10內設置有一感測單元12,感測單元12被配置為可接收一啟動訊號並感測第一燃料槽10內的丙二醇基液體燃料之液位,據以發出一補油訊號。第二燃料槽20供容納丙二醇基液體燃料。管路30連通第一燃料槽10與第二燃料槽20。驅動單元40設置於管路30上,且驅動單元40被配置為可接收補油訊號
,據以經由管路30將第二燃料槽20內的丙二醇基液體燃料補充至第一燃料槽10,藉此達到自動補充燃料並透過來自第二燃料槽20的丙二醇基液體燃料冷卻金屬燈芯11之功效。
Please refer to FIG. 1 and FIG. 2 , which are schematic appearance diagrams and partial cross-sectional diagrams of an embodiment of the combustion system of the present invention. The combustion system shown in this embodiment uses at least 90 wt% propylene glycol-based liquid fuel, and the combustion system includes a
進一步來說,在金屬燈芯11被點燃之前,感測單元12能夠預先感測第一燃料槽10內的丙二醇基液體燃料之液位,若為低液位則對驅動單元40發出補油訊號,使驅動單元40經由管路30將第二燃料槽20內的丙二醇基液體燃料補充至第一燃料槽10以達高液位;反之,若為高液位則可供使用者點燃金屬燈芯11。當金屬燈芯11被點燃而開始傳輸第一燃料槽10內的丙二醇基液體燃料使其燄端產生火焰時,一旦感測單元12感測到第一燃料槽10內的丙二醇基液體燃料被消耗至低液位時,即對驅動單元40發出補油訊號,使驅動單元40經由管路30將第二燃料槽20內的丙二醇基液體燃料補充至第一燃料槽10,而來自第二燃料槽20的丙二醇基液體燃料不僅能夠供給燃料維持火焰,還恰可冷卻當前被火焰加熱的金屬燈芯11,藉此達到自動補充燃料並冷卻金屬燈芯11之功效,同時避免金屬燈芯11因過熱影響火焰規模與型態。上述功效特別地是建立在丙二醇基燃料具有高閃燃點特性的基礎上,利用來自第二燃料槽20的丙二醇基液體燃料來冷卻已被火焰加熱的金屬燈芯11並穩定火焰規模與型態,一般乙醇或異丙醇基燃料並無法如此應用,因其閃燃點極低,一接觸到被火焰加熱的金屬燈芯11即被點燃,完全無法用於冷卻金屬燈芯11。Further, before the
此外,驅動單元40被配置為可另接收一關閉訊號
,據以經由管路30將第一燃料槽10內的丙二醇基液體燃料抽至第二燃料槽20。因此,當金屬燈芯11處於點燃狀態時,一旦驅動單元40接收到關閉訊號,即開始將第一燃料槽10內的丙二醇基液體燃料抽至第二燃料槽20,直至第一燃料槽10內的丙二醇基液體達到低液位而使金屬燈芯11無法產生火焰,或是將第一燃料槽10內的丙二醇基液體燃料完全地抽至第二燃料槽20,使金屬燈芯11燄端之火焰熄滅。由於金屬燈芯11在點燃狀態時會將燄端的熱量傳導至第一燃料槽10內的丙二醇基液體燃料,透過將其抽至第二燃料槽20也能夠使其降溫,更佳地是降至環境溫度,這同樣是應用丙二醇基燃料高閃燃點的特性,利用第二燃料槽20內的丙二醇基液體燃料將來自於第一燃料槽10內的丙二醇基液體燃料降溫。
In addition, the
進一步地,驅動單元40被配置為接收關閉訊號且將第一燃料槽10內的丙二醇基液體燃料之液位抽至無法被金屬燈芯11傳輸而產生火焰的高度,或是將第一燃料槽10內的丙二醇基液體燃料完全地抽至第二燃料槽20後(透過感測單元12感測)仍持續運作一預定時間,據以使驅動單元40延遲關閉以抽離因金屬燈芯11燄端之火焰熄滅所產生的廢氣。Further, the
為提高燃料的降溫效率,本實施例的第一燃料槽10的容積小於第二燃料槽20的容積,且更佳地,第二燃料槽20的容積至少為第一燃料槽10的容積之十倍以上。In order to improve the cooling efficiency of the fuel, the volume of the
進一步地,本實施例的燃燒系統所使用的至少90 wt%丙二醇基液體燃料,更佳地能夠包含95 wt%的丙二醇。Further, at least 90 wt% propylene glycol-based liquid fuel used in the combustion system of this embodiment can more preferably contain 95 wt% propylene glycol.
本實施例的管路30能夠包括一連接於第一燃料槽10與驅動單元40之間的第一管段31及一連接於驅動單元40與第二燃料槽20之間的第二管段32。The
本實施例的驅動單元包括一馬達41,其可經由管路30將第二燃料槽20內的丙二醇基液體燃料補充至第一燃料槽10,或經由管路30將第一燃料槽10內的丙二醇基液體燃料抽至第二燃料槽20。The driving unit of this embodiment includes a
