Description: Chiefly for improved efficiency, the trend to increasing use of gas turbine engines in stationary powerplants has been firmly established. The requirement for minimum NOx production has motivated operation as close as practically possible near the lean flammability limit, to reduce formation of nitrogen oxides by the Zeldovich thermal mechanism. However, experience has shown that under these conditions, stability of the chamber is reduced, often leading to the presence of sustained oscillations in the combustor. That possibility raises the problem of the influence of oscillatory motions on the production of nitrogen oxides. The work represented in this paper covers the initial steps in constructing an analysis suitable for application to that problem in design and development of operational gas turbine combustors.
