Abstract

A catalytic combustor bed configuration particularly adapted for use in wood and coal burning stoves is described comprising a support screen having a layer of fully catalyst impregnated particulate material next to the screen, a layer of particulate material catalyzed on its outer surface next to the layer of fully impregnated material and a layer of uncatalyzed particulate material next to the outer surface catalyzed material. Optionally, a layer of uncatalyzed particulate material may be used between the screen and the fully impregnated particulate material. Such an arrangement, in addition to making maximum utilization of the catalyst material, also minimizes pressure drop across the catalytic combustor.
