Control of primary measures for the reduction of NOx in gas turbines

摘要

The method involves controlling primary measures for a reduction of the thermic nitric oxide formation, based on a parameter which describes a air volume-specific heat release rate in a combustion chamber of the gas turbine. A power available at an output side of a profit power shaft of the gas turbine is used to iteratively determine the heat release rate. The air volume is determined in response to environmental conditions and an operating mode of the machine.
