Measurements are reported for a spark-ignited (SI) engine burning natural gas and three simulated biogas fuels (natural gas, CO2, and N2 mixtures). Exhaust concentrations of CO, CO2,O2,NOx, and unburned hydrocarbons, as well as brake power and brake specific energy consumption, were measured. Leaner mixtures, retarded spark timing and diluent addition CO2,N2 yielded reduced NOx emissions. NOx reductions up to 50 percent were achieved at MBT timing through diluent addition. Reduced peak temperatures caused by diluent addition, lean conditions, and retarded spark timing reduced combustion quality slightly, as evidenced by small increases in CO and unburned hydrocarbons emissions.

Underlying Processes

This paper addresses the impact of fuel composition on the operability of lean premixed gas turbine combustors. This is an issue of current importance due to variability in the composition of natural gas fuel supplies and interest in the use of syngas fuels. Of particular concern is the effect of fuel composition on combustor blowout, flashback, dynamic stability, and autoignition. This paper reviews available results and current understanding of the effects of fuel composition on the operability of lean premixed combustors. It summarizes the underlying processes that must be considered when evaluating how a given combustor’s operability will be affected as fuel composition is varied.
