Combustor for gas-turbine

Abstract

Abstract PURPOSE:To obtain the gas-turbine combustor having a catalyst, highly active and with long life in the temperature range of 350-900 deg.C substantially, by a method wherein a catalyst body, carrying silica alumina containing a noble metal and rare earth oxide on a heat resistant carrier, is provided in the combustor. CONSTITUTION:In the gas turbine combustor, in which the mixture of fuel and air is burnt by catalytic combustion system, the catalyst body, carrying silica alumina containing noble metal and rare earth oxide on the heat resistanct carrier, is provided. The low-temperature activity of the catalyst body is improved by containing the noble metal and the durability thereof in high temperature is contrived to improve by containing rere earth oxide in silica alumina. Further, the catalyst body 8 is preferable to be constituted of a fore-stage catalyst 8a and an aft-stage catalyst 8b which have characteristics provided with activities in respective temperature ranges especially.
