Abstract
ECN ceramic foam burners, originally designed to burn premixed air/natural gas, turn out to be suitable for burning mixtures of H{sub 2} and CH{sub 4} up to a H{sub 2}/CH{sub 4}-ratio of 70/30 (by volume) at any air ratio at power densities ranging from 200 to 2000 kW/m{sup 2}. No catalyst is used. NO{sub x} emissions were relatively low (5-50 ppm) compared to a commercially available nozzle mix burner (90-120 ppm) measured at 30% excess air. Recently, ECN developed a new (non-catalytic burner), capable of burning hydrogen-rich fuels with extremely low NO{sub x}-emissions: under 5 ppm NO{sub x} measured at 30% excess air. This new burner is still under investigation. 7 figs., 4 refs.
