本論文利用直管量測系統量測火焰在直管內傳遞速度與火焰焰面面積變化,以求得甲烷與一氧化碳在當量比為1.0時甲烷(CH4)與一氧化碳(CO)不同混合比例的層流火焰速度。藉由探討混合燃氣之層流火焰速度來分析其燃燒特性,作為有效利用混合燃氣的參考依據。
實驗觀察顯示20%[CH4]/80%[CO]為分界點,CO比例由0%增加至80%時,火焰傳遞速度與層流火焰速度是呈現增加的趨勢,但是當CO的比例超過80%,火焰傳遞速度與層流火焰速度反而開始衰減。因此判斷在CH4添加0%~80%的CO可以提升火焰溫度,所以層流火焰速度增加,其反應主要由CH4主導。在CO中添加0%~20% CH4可以增加反應速率,進而提升層流火焰速度,反應由CO主導。實驗與模擬趨勢吻合,但是模擬忽略熱對流與熱輻射的影響,所以造成實驗與模擬結果的誤差。
研究顯示火焰焰面面積會隨著火焰傳遞速度增加而增加,而火焰面積受到熱傳效應與浮力效應影響,由實驗結果研判混合燃氣中添加CO會造成火焰溫度變化,使得熱傳效應與浮力效應的影響也改變,進而影響火焰面積與火焰傳遞速度。
This thesis measures the flame propagation speed and the flame area to calculate the laminar flame speed in different ratio of CH4/CO mixtures in stoichiometric in tube system. We hope to analysis conducivily the characteristic of the synthgas by studying the laminar flame speed. To understand the characteristic of the synthgas can advise how to effective use.
Observe of the experiment discover the maximum of the flame propagation speed and the laminar flame speed in 20%[CH4]/80%[CO]. And the mixture ratio of synthgas is a parting. When the carbon monoxide ratio changes from 0% to 80%, the flame propagation speed and the laminar flame speed show to increase gradually. Because the flame temperature increases with the carbon monoxide ratio increased, the laminar flame speed rises. Methane controls the reaction in the process. When the carbon monoxide ratio of synthgas exceeds in 80%, the flame propagation speed and the laminar flame speed begin to decrease instead. The process can look on as the methane add to the carbon monoxide. Methane can make the reaction rate rises to help the laminar flame speed increases. And the carbon monoxide controls the reaction. The experiment matches with the simulation. The simulation neglects heat convection and heat radiation effect to make the error.
The flame area has relation to the flame propagation speed. The relation is the flame area to increase with the flame propagation speed increased. The research analysis shows the flame area to be effected by the heat transfer effect and the buoyancy effect. The flame temperature changes by the the carbon monoxide ratio of synthgas change. And to make the heat transfer effect and the buoyancy effect vary. The flame propagation speed and the flame area are effected,too.
