Abstract
In order to get more information of laminar burning characteristics of biogas under different compositions and hydrogen fractions, an experimental study is performed in a constant volume vessel by using the Schlieren system to investigate the laminar burning velocities of CH4/CO2premixed flames under various CO2fractions and various H2fractions associated with different equivalence ratios at atmospheric pressure and elevated pressures. The unstretched burning velocities of biogas premixed flames decreases with increasing CO2fraction. The value of unstretched burning velocities decreases with increasing initial pressure with a specific equivalence ratio and CO2fraction. The unstretched burning velocities of biogas premixed flames increases with increasing H2fraction. The flame stability decreases with the increasing pressure and hydrogen fraction, the flame stability increases with the increasing equivalence ratio, but the CO2has little influence on the flame stability.关键词
