N2 - A combustion rig was used to determine the coefficient of restitution of bituminous ash particles in a simulated gas turbine environment up to temperatures of 2100°F. The impact angle, impact velocity, particle size, and particle temperature were varied, and the effects of these variables on the particle rebound characteristics were examined. For the ash tested in these experiments, it was found that the total coefficient of restitution generally decreased with particle size and impact velocity. Unexpectedly, the coefficient of restitution increased with temperature up to approximately 1500-1750°F, before decreasing at higher temperatures. Similarly, the coefficient of restitution increased with increasing impact angle up to approximately 40°, before generally decreasing toward 90°. Possible explanations for these trends are discussed.
