Nitric Oxide Reduction in Stationary Power Engines Using Oxy-Combustion
This study investigates nitric oxide (NOx) production in a spark-ignited, internal combustion piston engine under oxy-combustion conditions. An engine has been modified for oxy-combustion operation, using either EGR or CO2 working fluid. Three parametric studies were carried to study NOx production levels under oxy-combustion conditions: changing N2 concentration, changing O2 concentration while leaving N2 constant, and investigating different working fluids and compression ratios. It was found that under constant power conditions, NOx production varies linearly with N2 concentration. Varying the oxygen concentration significantly altered the NOx production, though brake mean efficiencies of all cases were similar. CO2 working fluid produced better power and lower NOx than EGR working fluid, however, both cases showed that with 3% N2, current regulatory NOx levels cannot be attained while maintaining a reasonable COV IMEP.
