Using an experimental catalytic combustor which has the function of variable heat insulation by external heating, the ignition and blow-off tests were carried out with lean propane air mixture. A newly developed heat-resisting catalyzer was used for comparing the performance with conventional catalyzer consisting of graded cell honeycomb support with a noble metal catalyst coating. By measuring a change of temperature profile in the honeycomb element, and observing the temperature distribution on the rear end surface of the element by making use of the infrared camera, the characteristic region of lean catarytic combustion was made clear. Results showed the dynamic behavior of the catalytic combustor primarily depended on the heat balance at the inlet of the catalyzer element, and the critical condition of combustion termination were determined by the relation between the energy supplying rate and the characteristic residence time.
