Effect Of Air-Fuel Ratio on Temperature Distribution and Pollutants For Biogas Mild Combustion

Effect Of Air-Fuel Ratio on Temperature Distribution and Pollutants For Biogas Mild Combustion

This paper examines the effect of air-fuel ratio for Moderate or Intense Low oxygen Dilution (MILD) combustion using a bluff-body burner. Exhaust gas recirculation was used to dilute the oxidizer stream prior to the combustion chamber. A low-calorie biogas fuel which consists of 60% methane and 40%...
