An application and process that incorporates an external heat source to increase the temperature of the airstream entering a compressor section of a combustion turbine. The application and process may perform an anti-icing operation that may not require an Inlet Bleed Heat system (IBH) to operate. Additionally, the application and process may perform an anti-icing operation that may allow for the IGV angle to remain nearly constant. The application and process may increase the output and efficiency of a combustion turbine operating at partload by delaying IBH operation and delaying the closing IGVs.
