ABSTRACT

The experimental results of premixed methane-air combustion within two different porosity-reticulated porous ceramic inserts are presented. The burner's radiant output and emissions of CO and NO_x were measured under various equivalence ratios and flame speeds. The results indicated that CO and NO_x emissions increased with flame speeds. The radiation efficiency decreased with flame speeds at a lower equivalence ratio. At a higher equivalence ratio the radiation efficiency of the ceramic burner is relatively constant. The burner has high radiation efficiency and as low CO and NO_x emissions as other commercial ceramic fibrous burners, but it operates at a much higher combustion temperature.
