This work presents an experimental study with the use of biodiesel, diesel, natural gas and mixtures operating in a gas microturbine as fuel. The main objective of the study is to understand the emissions produced by the fuels. The experimental apparatus was constructed entirely for the purpose of performing tests with natural gas and changes in the supply line were made for the supply of liquid fuel, no changes were made in the combustion chamber. The experiments were performed for rotations of 45.000rpm, 50.000rpm, 55.000rpm and 60.000rpm. By the experimental difficulties encountered in understanding the combustion process and its emissions, a complementary procedure for the emissions estimation is presented, resolving and estimating the composition of emissions through ComGas V1.0 software which calculates combustion in the equilibrium. As a contribution, we present experimental data for CO, CO2, O2, gas exhaust temperature, mass flow rates, molar flow rates, and energy characterizing of fuels and mixtures.
