Active Control of MILD Combustion for Gas Turbine Applications

摘要

In this work the active control of MILD (moderate or intense low oxygen dilution) combustion for gas turbine applications is investigated. For this purpose, a new concept for pulsation of the air flow is introduced. The pulsating unit offers the possibility to vary the pressure fluctuations with a high degree of freedom during runtime. Based on this concept the influence of pressure pulsation on the MILD combustion is analyzed in terms of pollutant NO_x and CO emissions. For deeper insights into the combustion process, OH~*-chemi-luminescence measurements are performed.
