Abstract

For methane-air mixture the flame structure of premixed CH4-air in a small tube with a parabolic and constant velocity profiles at inlet for various equivalence ratios is numerically investigated. The equivalence ratio is a key and dominating parameter that affects the combustion characteristics and hence the flame temperature. The highest flame temperature is obtained if the equivalence ratio is set at 0.9.The combustor geometry is an important factor which affects the zone of maximum temperature in combustor. In syn gas CO consumption rises with increase in combustor temperature while in methane CO concentration is maximum around outer envelope of flame it rises up to a certain temperature and decreases with further increase in temperature. In syn gas and methane carbon dioxide concentration decreases with increase in velocity because of incomplete combustion. For stoichiometric air-fuel ratios with same operating conditions syn gas emission of carbon mono oxide and carbon dioxide is more than methane-air mixture
