Producer Gas (PG) is derived from the biomass gasification process of carbon compounds such as coal and wood. This gas can be used as an alternative way from the burning of fossil fuel to generate power. The development of a PG burner, designed to burn the raw PG efficiently. Higher carbon monoxide (CO) composition in the PG element makes the combustion process and the heating value low. The burning of PG also has limitations since there were emissions of CO and oxide of nitrogen (NOx). The number of CO and NOx emissions should be lower than possible since it indirectly affects Greenhouse Gas (GHG). It may not directly be affecting GHG since the main component of GHG itself are made up of water vapour (H₂O), carbon dioxide (CO₂), methane (CH₄), ozone (O3), nitrous oxide (N₂O), chlorofluorocarbon (CFC). However, the emission of CO and NOx may react to the tropospheric ozone that can lead to a worse world of pollution. Many studies were found out that PG could be as efficient as fossil fuel and cleaner. The studies carried out that emission levels of CO and NOx can be reduced due to the complete combustion of PG. There were few methods in improving the burning of PG for the energy conversion project. The method including, 1) the ratio fuel to air, (2) geometry of the burner, (3) Biomass sources for PG, (4) Flow dynamic of PG, etc. This study will focus on the geometry of the burner to have a good result in a low emission level of CO and NOx. There are three factors to be used to run the experiment, which are (1) the outer diameter of the burner, (2) the ratio diameter of the fuel holder, and (3) the ratio length of the fuel holder. The effect of these factors was studied through numerical simulation. The experiment and numerical simulation will characterize the PG burner when the gas is burned in several methods as improved combustion performance. Overall, the optimum geometry is found out among the factors from this experiment.
