inlet end of the combustor the boundary of each coated channel has a thermal barrier to inhibit the flow of heat from the coated channel to an adjacent uncoated channel also in the vicinity of the inlet end the coated channels may include one or more additional coated members to enhance catalytic combustion in the light off zone the combustor of the present invention lights off at a relatively low temperature and quickly reaches a stabilized and controlled operating temperature application_number US 9869302 A description fig2 provides a cross sectional view of a catalytic combustor of the present invention taken at a position other than at the inlet end the structure shown in fig2 is similar to that of prior art combustors except that the prior art combustors have the same structure throughout including the inlet end the combustor of fig2 includes flat metal strips 1 2 3 which alternate with corrugated strips 4 and 5 in this specification the corrugated strips 4 and 5 are sometimes designated u201c primary u201d corrugated strips to distinguish them from additional corrugated strips to be described later the primary corrugated strips are so called because they define the basic structure of the combustor the strips shown in fig2 define a plurality of channels for gas flow in the view shown the gas flows in a direction perpendicular to the paper the walls of some of the channels are coated with catalyst and the walls of other channels are uncoated in this specification a channel whose walls are.
