As part of the Department of Energy’s Advanced Gas Turbine Systems Program, an investigation is being performed to evaluate “pressure gain” combustion systems for gas turbine applications. This paper presents experimental pressure gain and pollutant emission data from such combustion systems. Numerical predictions for certain combustor geometries are also presented. We report that for suitable aerovalved pulse combustor geometries studied experimentally, an overall combustor pressure gain of nearly 1 percent can be achieved. We also show that for one combustion system operating under typical gas turbine conditions, NOx and CO emissions, are about 30 ppmv and 8 ppmv, respectively.
