Intelligent control method with predictive emissions monitoring ability for a gas turbine combustor

摘要

The present invention relates to a combustor system (100) for a gas turbine engine. The combustor system (100) comprises a combustion chamber (101) into which a pilot fuel (102) and a main fuel (103) is injectable and flammable, wherein an exhaust gas (104) generated by the burned pilot fuel (102) and the burned main fuel (103) is exhaustible out of the combustion chamber (101). A control unit (112) is coupled to a fuel control unit (105) for adjusting the pilot fuel (102) ratio. The control unit (112) is adapted for determining a predicted pollutant concentration of the exhaust gas (104) on the basis of a temperature signal, a fuel signal, a mass flow signal and a fuel split ratio.
