The study of air fuel ratio for open furnace MILD combustion of biogas on bluff-body burner [PDF]

, 2012
Economical fuel cost is very critical in the heating industry. Lean combustion with high air fuel ratio (AFR) is normally practiced by the industry. Low air fuel ratio or rich combustion will result in unburned hydrocarbons (UHC).
