I wish to understand why does the gas turbine need pilot burner as well as the main burner. I am working with SGT700, the burner fuel supply is split into Main gas and Pilot gas.
The main gas get mixed with the compressed air and burns inside the burner. The pilot gas is supplied at the tip and burns there. Both the pilot and the main gas valves are open during operation.
I wonder if the burners had only the main fuel supply and one of them had a pilot burner with igniter assembly, for the fire to start, how would it affect. The point I wish to discuss upon is why do we even need a pilot burner can the main burner not achieve the same goal, making them perhaps a bit bigger?
