ABSTRACT:
A catalytic combustor is formed of a plurality of segments which are enclosed within a canister. Each segment includes a metal strip which is folded back and forth upon itself. The strip is coated with catalyst on only one side, and the strip is brazed or welded to the canister only on the uncoated side. The segments of the combustor substantially fill the cross-section of the canister, but these segments are not physically joined to each other. The structure described above makes it possible to make the combustor relatively flat, having a length to diameter ratio of 0.25 or less. The catalytic combustor of the present invention is especially useful in a gas turbine, where space is limited, and where catalytic combustion is useful in preventing the formation of NOx.
