Fuel variability plays a major role in biogas combustion utilisation, where modelling and simulation can be used to provide guidelines. The construction of a flamelet generated manifold (FGM) is an important step for the simulation of complex turbulent flames. The FGM is made from premixed laminar flames and the limited literature on biogas combustion has led to this study on the effects of the fuel composition on biogas combustion in a freely propagating laminar premixed flame. The results have shown that methane concentration has a significant impact on the combustion process. There was no major difference observed among fuel mixtures with a fixed CH4 volume concentration of 50%, with CO2 varied from 40%, 49% to 50% and completed with either 10% of N2 or 1% H2. The study can be further extended for numerical simulations under more realistic and practical conditions in order to develop guidelines for industrial combustors.
