Development of a methane premixed catalytic burner for household applications
A catalytic premixed burner prototype for domestic-boiler applications was developed on the basis of a perovskite-type catalyst (LaMnO{sub 3}) deposited over a FeCrAlloy fiber panel. An economic and simple catalyst-deposition route, based on in situ pyrolysis of suitable precursors, was conceived and optimized on purpose. Finally, a catalytic burner and a reference noncatalytic one were comparatively tested in a pilot plant (maximum power, 30 kW, corresponding to about 2,000 kW/m{sup 2}). The catalytic burner allowed a strong reduction of CO and unburned hydrocarbon (HC) emissions to very low and acceptable levels (down to 3--5 times lower than those of the noncatalytic burner) when operated below 800 kW/m{sup 2}. In these conditions, the NO{sub x} emissions remained quite acceptable and practically unaffected by the presence of the catalyst.
