Basic research on radiant burners. Annual report, January 1989-March 1990
Flame liftoff and flashback characteristics of several types of radiant burners were studied in the first and second years of the contract. In this, the third year, radiant output and nitrogen oxides emissions from porous surface radiant burners were studied. Gas phase radiation and its contribution to total radiant output was the primary subject of the third year of research. Gas phase temperatures were determined using Alzeta's PROF (PRemixed One-dimensional Flame) code, and gas phase radiation was calculated using the predicted temperatures and the Hottel method. These predictions were compared to experimental results of ceramic fiber and metal fiber burner tests. Nitrogen oxides emissions were also predicted using the PROF code and an extended chemical kinetics set, and these predictions were compared to experimental results.
