Driven by the need for a new generation of low emission energy systems, research has been conducted that explores the possibility of using unsteady burners to yield significant reductions in environmentally harmful emissions, specifically NO and NO2. Presented here are the results obtained using a small scale fluidic natural gas burner. This fluidic slot burner was operated to measure the effects of: oscillation frequency, from 0 to 60 Hz; the equivalence ratio (phi), varied from 0.6 to 1.4; and the burner diffuser angles (theta) of 30 degrees, 50 degrees and 70 degrees. When the emissions data obtained from these runs were compared to those obtained using a steady state slot nozzle, dramatic reduction in NO, production was found throughout most of the frequency range. Additionally, a region of significant NO, reduction was discovered for many test conditions at oscillation frequencies around the 10-15 Hz range. With the burner operating at an equivalence ratio of 1.0, the maximum observed NO, reductions were 46.5% for theta = 30 degrees, 40.9% for theta = 50 degrees and 46.1% for theta = 70 degrees.
