Measurements of Emissions and Radiation for Methane Combustion within a Porous Medium Burner

Abstract

In this paper, we report the results of an experimental investigation of methane-air combustion within a porous medium burner for various equivalence ratios and flow rates. Measurements of emissions and radiant output are presented. The results indicate that CO and NO_x, emissions increase with flame speed. For a given equivalence ratio, however, NO_x, emissions are fairly constant over the range of flame speed studied. The radiant output increases but the radiant thermal efficiency decreases with flame speed.
