A high temperature-low NOx combutor is required for high efficiency gas turbines to restrain a global warming by means of reducing energy consumption. In realizing both of high temperature and low NOx combustion, CST (catalytically stabilized thermal) combustion is considered to be the most promising in the low pollution combustion. In this study, previously reported new concept of the catalytic combustor with starting burner is combined with CST combustion to achieve the high temperature of the burned gas over the heat resisting temperature of the catalyst. The developed catalytic combustor have unique structure with the cooling system of the heated catalyst by flowing the low temperature mixture to the catalyst. In the 1st report, the proposed combustion system description and optimized mixture formation were illustrated. This paper describes the emission characteristics of the developed combustor and the validation of the combustor structure composed of ceramic components and catalysts with the result of the high temperature combustion test of 100hrs.
