| 摘 要： | 在定容燃烧弹上采用高速纹影系统对模拟沼气预混层流火焰的燃烧特性进行研究。模拟沼气为甲烷含量70%～75%和二氧化碳含量25%～30%的混合气。对不同成分的模拟沼气和纯甲烷的燃烧速度及燃烧压力进行了对比分析。研究结果表明,沼气中较高含量的二氧化碳对燃烧有强烈的抑制作用,使沼气的燃烧速度与纯甲烷相比有所下降,并且随着成分中二氧化碳含量的增加,整个燃烧过程延长。

| Abstract: | The combustion characteristics of premixed laminar flame for simulated biogas are studied in a constant volume combustion bomb by using high-speed schlieren photography.The components of simulated biogas contain methane and CO2,the methane content is from 70% to 75%,CO2 content is from 25% to 30%.The burning speed and combustion pressure of simulated biogas with different components are compared with pure methane.Experimental results show that the burning speed of biogas decreases compared with pure methane because CO2 restrains flame from spreading,and the combustion process extends with the increase of CO2 proportion. |
