    摘要:

    在一臺(tái)火花點(diǎn)火發(fā)動(dòng)機(jī)上，分別進(jìn)行了生物質(zhì)燃?xì)庵锌扇冀M分CH4、CO和H2的燃燒試驗(yàn)，研究并對(duì)比了各組分氣體的燃燒及排放特性。結(jié)果表明，H2燃燒快，熱效率高，NOx排放水平較低；CH4和CO相比具有較高的熱效率和較低的NOx排放水平，但其稀燃能力較弱；在實(shí)際生物質(zhì)燃?xì)庵锌梢酝ㄟ^提高H2的含量來擴(kuò)展稀燃極限以及提高熱效率。

    Abstract:

    Combustion experiments of CH4,H2 and CO were carried out in a spark-ignition engine under 1500r/min engine speed, and the combustion and emission characteristics were analyzed. The results showed that H2 had the fastest burning velocity, the highest thermal efficiency and the lowest NOx emission. Comparing with CO, CH4 had higher thermal efficiency, lower NOx emission and poorer lean burn ability. In practical application, it had potential to improve lean burn limit and thermal efficiency of biogas by mixing with H2.
