Zusammenfassung:	A method of operating a combustor (10) in a gas turbine that receives combustion air from a compressor (12) includes a) controlling combustion temperature as a function of compressor discharge air bled from the compressor (12) by determining a minimum amount of compressor discharge air required for maintaining a predetermined minimum combustion temperature; and b) bleeding compressor discharge air in excess of the minimum amount from the compressor via a control valve (30).
