CO为主燃料的混合燃料预混火焰燃烧特性研究

Study on the Premixed Flame Characteristics of CO as the Main Fuel Mixed Fuel

以CO为主燃料的混合燃料为对象,应用Chenkin软件,采用包含53种组分、325个基元反应的甲烷燃烧详细反应机理(GRI-Mech 3.0),研究了CO为主燃料的混合燃料预混火焰燃烧特性。结果表明:CO为主燃料的混合燃料最大火焰温度和最大层流燃烧速度都出现在富燃料侧,添加H2可以显著提高火焰温度和火焰的燃烧速度。

In the present research the premixed flame characteristics of CO as the main fuel mixed fuel was numerically studied with the chemkin software using a detail methane kinetic mechanism containing 53 species and 325 elemental reactions.The results revealed：flame temperature and laminar burning velocity of CO as the main fuel mixed fuel reaches maximum when the fuel is rich;flame temperature and laminar burning velocity increased when H2 is added to the mixed fuel.
