ABSTRACT

Lean premixed fuel mixtures of hydrogen and methane are tested in two different burners developed at The Norwegian University of Science and Technology. The burners include a catalytic burner and a catalytically supported porous inert media burner, both using commercial catalysts. The thermal loads are varied up to 15 kW. Measurements performed of CO₂, O₂, NO_x, and CO in the flue gases verify very low emission levels. The catalytic burner shows severe loss of activity during long-term testing, whereas the catalytically supported burner indicates long-term durability. Applications for such burners could be clean and efficient small-scale combined-heat-and-power systems, either in combination with fuel cells or in Stirling engines.
