Abstract

To better understand the effects of ammonia as a fuel additive, both the adiabatic burning velocities and combustion emissions were determined for premixed methane-air and ammonia-methane-air flat flames. The experimental results of this work were compared to chemical kinetic (CHEMKIN III) and thermodynamic (STANJAN) simulations as well as literature values. The literature provided limited information on emissions from ammonia-methane-air flames. There was also a lack of information regarding the burning velocities of these mixtures. A flat flame burner was built on the basis of the design of the perforated plate burner of van Maaren et al. [1993]. This burner facilitated the direct measurement of the adiabatic burning velocity based on the measurement of the unburned gas velocity. Using a 5-gas analyzer and a chimney, NO, NO 2, CO, CO2 and O2 emissions from various mixtures of ammonia-methane-air were determined. The burning velocity data for methane-air mixtures was found to be in good agreement with the literature and chemical kinetic simulations. For additions of 1% to 4% ammonia in the fuel, both the experimental observations and kinetic simulations revealed premixed ammonia-methane-air flames yield lower burning velocities than pure methane-air flames and result in a significant increase in NO emissions. In agreement with Wendt et al. [1974], the formation of NO in these flames appeared to be independent of thermodynamic equilibrium.Dept. of Environmental Engineering.
