摘要

本文主要在探討氫氣對預混合丁皖氣體燃料的冷火焰燃燒波傳播速度與最高燃燒壓力的影響，期望藉由氫對氣體燃料之燃燒特性影響研究以建立混合燃料燃燒技術。從本研究結果中可以發現丁烷加入氫氣後，可加速混合氣的反應速率，對提高火焰傳播速度也有明顯的助益。同時經由壓力訊號比較後得知，燃燒氣中含10%氫氣並不會影響初始點火所形成之冷火焰燃燒波的最大壓力，然而發生在冷火焰燃燒波後的劇烈燃燒情況下，含有部分氫氣的混合氣，其最大燃燒壓力有明顯的降低現象，但隨著Φ值的提高，這壓力降有減少的趨勢。

Partial premixed gases of butane and ten percent volume hydrogen contained partial premixed butane are used to study the influences on cool flame propagation speed and maximum combustion pressure of hydrogen addition to the fuel. Results show that, the reaction rate and the flame propagation speed of the partial premixed gases were increased as hydrogen addition to the butane. In addition, hydrogen addition to the butane cannot affect the cool flame wave pressure of initial ignition. After the cool flame wave sweeps the partial premixed gases, abruptly combustion occurred and the maximum chamber pressure appeared during combustion process. However, the maximum chamber pressure is lower when hydrogen addition to the butane, but the higher equivalence ratio can prevent the lower maximum chamber pressure phenomenon.
