Evaluation of advanced combustion concepts for dry NO sub x suppression with coal-derived, gaseous fuels [PDF]
The emissions performance of a rich lean combustor (developed for liquid fuels) was determined for combustion of simulated coal gases ranging in heating value from 167 to 244 Btu/scf (7.0 to 10.3 MJ/NCM). The 244 Btu/scf gas is typical of the product gas

Linear Instability Analysis of Lean Premixed Combustion
Journal of Thermal Science and Technology, 2012 Combustion oscillation of a self excited combustion-acoustic phenomenon occurs inside the gas turbine combustor. In general, excessive pressure fluctuation of combustion oscillation may impair the gas turbine engine operation and may result in hardware damages.

Ultra-lean combustion at high inlet temperatures [PDF]
Combustion at inlet air temperatures of 1100 to 1250 K was studied for application to advanced automotive gas turbine engines. Combustion was initiated by the hot environment, and therefore no external ignition source was used.

Coupled thermoacoustic interactions in hydrogen-enriched lean combustion
Experiments in FluidsIn this paper, we present a framework to study the synchronization of flow velocity with acoustic pressure and heat-release rate in technically-premixed swirl flames. The framework uses the extended proper orthogonal decomposition to identify regions of the velocity field where velocity and heat release fluctuations are highly correlated. We apply this
