In this study, temperature distributions from turbulent chemical reactive flow inside a model combustor have been presented for various mixtured hydrogen-methane fuels. The gas emissions were also obtained at the combustor exit. A platinum-platinum 13% rhodium thermocouple (R type) was used for measurement of axial and radial temperatures. The axial and radial temperature measurements were taken from six various distances and four distances, respectively. Experimental measurements were made at excess air ratios of 1.2 and 1.7, two various thermal powers including 40 and 60 kW and two various hydrogen-methane, blending fuels (volumetrically 30% H-2-70% CH4 and 70% H-2-30% CH4). The results show that the temperature level increases, CO and CO2 emissions decrease when the hydrogen content is increased in mixtured fuel, hydrogen-methane mixtured fuels are successfully used without any important modification in natural gas burner.
