Abstract
A catalytic combustor () includes a first catalytic stage (), a second catalytic stage (), and an oxidation completion stage (). The first catalytic stage receives an oxidizer (e.g.,) and a fuel () and discharges a partially oxidized fuel/oxidizer mixture (). The second catalytic stage receives the partially oxidized fuel/oxidizer mixture and further oxidizes the mixture. The second catalytic stage may include a passageway () for conducting a bypass portion () of the mixture past a catalyst (e.g.,) disposed therein. The second catalytic stage may have an outlet temperature elevated sufficiently to complete oxidation of the mixture without using a separate ignition source. The oxidation completion stage is disposed downstream of the second catalytic stage and may recombine the bypass portion with a catalyst exposed portion () of the mixture and complete oxidation of the mixture. The second catalytic stage may also include a reticulated foam support (), a honeycomb support, a tube support or a plate support.
