The most crucial phenomenon limiting gas turbine burner operation is the flashback and blowoff of flame in the combustor during gas turbine operation. In order to avoid this undesirable phenomenon, it is necessary to predict the operational map area of the gas turbine burner.
Pure methane has been taken as fuel in this analysis, which attempts to construct a design map with two swirl numbers, 1.2 and 1.5. Different configurations for the outlet of the burner ranged from open flame with a normal nozzle, to cylindrical and conical confinements.
The operation map area represents the allowance area of the burner when choosing the equivalence ratio and specified total mass flow rate. The results show that the workable area of the burner increases with the cylindrical and conical confinements, but shows no real difference between the two swirl numbers.
