Abstract:
A method for light-off of a gas turbine engine comprising:a. determining ambient conditions and fuel heating value; b. accelerating a gas turbine engine at a preset acceleration rate to a speed to provide a supply of combustion air to a combustor for light-off of said gas turbine engine, wherein said preset acceleration rate of said gas turbine engine is determined based upon said ambient conditions and said fuel heating value; c. activating an ignition source for said combustor of said gas turbine engine; and d. initiating a flow of fuel to said combustor at a substantially constant rate via a fuel line to provide an optimum supply of fuel to said combustor and maintaining said constant rate until the correct fuel-to-air ratio is achieved and light-off of said gas turbine engine occurs.
