A method of operating a combustor in a gas turbine that receives combustion air from a compressor includes a) controlling combustion temperature as a function of compressor discharge air bled from the compressor 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.

Control of gas turbine combustion temperature by compressor bleed air

An optimized combustor cooperating with a compressor in driving a gas turbine comprises a cylindrical outer combustor wall having an upstream fuel entry region and a downstream turbine entry region. An array of mixing holes are disposed about the periphery of the outer combustor wall adjacent to the fuel entry region so as to lower No,production therein. An array of dilution holes are medially disposed within the outer combustor wall to provide an entry for dilution air to the combustor.
