Abstract :This study concentrates on the numerical analysis of combustion of different oxidisers and numerical analysis of distributed combustion. The primaily aim of this study is to investigate the combustion properties of different equivalence rate , which are temperature and emission values, with a burner. It was carried out with biogas and a mixture of gas, then temperature and emission values were examined at different points in the model burner in this study. This experimental work has been repeated numerically at the different conditions with equivalance ratio. In addition, numerical studies have been carried out with 1.25, 1, 0.83 and 0.71 equivalance ratio, respectively. In the numerical study, gas of mixture 50% O2 - 50% CO2 was used for air on combustion biogas. It was observed that as the equivalence rate increased, the temperature values in the combustion chamber decreased axially on the distributed combustion.
