Biogas released from palm oil mill effluent (POME) could be a source of air pollution, which has illustrated negative effects on\nthe global warming. To protect the environment from toxic emissions and use the energy of POME biogas, POME is conducted\nto the closed digestion systems and released biogas is captured. Since POME biogas upgrading is a complicated process, it is not\neconomical and thus new combustion techniques should be examined. In this paper, POME biogas (40% CO2 and 60% CH4)\nhas been utilized as a fuel in a lab-scale furnace. A computational approach by standard k-? combustion and turbulence model is\napplied. Hydrogen is added to the biogas components and the impacts of hydrogen enrichment on the temperature distribution,\nflame stability, and pollutant formation are studied. The results confirm that adding hydrogen to the POME biogas content could\nimprove low calorific value (LCV) of biogas and increases the stability of the POME biogas flame. Indeed, the biogas flame length\nrises and distribution of the temperature within the chamber is uniformwhen hydrogen is added to the POME biogas composition.\nCompared to the pure biogas combustion, thermal NOx formation increases in hydrogen-enriched POME biogas combustion due\nto the enhancement of the furnace temperature.
