Researchers are trying to find alternative fuels to traditional fuels as traditional fuels are running out. This study is to predict turbojet gas turbine emission and performance using Methane and Biogas fuel blend for turbojet in Gasturb-14 program. Based on the physicochemical properties of each fuel, parameters were calculated for methane supplemented B1, B2 and B3 and pure methane fuel compositions. The heat of combustion for each blend was then obtained using GasTurb Details6 and the design points of the turbojet engine were determined. The program was run using biogas fuels to analyze performance and emission characteristics such as carbon monoxide, carbon dioxide, etc. In this study, the B3 blend was found to be the most effective Specific Fuel Consumption value with 32.22 g/kNs. It also produced lower emission rates for CO and CO2 compared to B1 and B2 fuels. The first finding is that it is possible to burn an alternative biogas fuel to methane fuel. The results also show that biogas is very similar to methane in terms of temperature distributions in the combustion chamber due to its high methane content compared to other biogases.
