The present work deals with the biogas in a combustor with regard to its combustion features under differing conditions of H₂0 content and H₂S. The content of water (H₂O) vapour has been changed from 0% to 10% and a CFD code has been employed while implementing numerical investigations. In modelling, a combustion model (the PDF/Mixture Fraction) along with a turbulence model (the k-Ɛ standard turbulence model) has been utilised. This study also deals with the combustion performances of the biogas by the addition of a different quantity of H₂O into the biogas. The Emissions and the flame temperature of the biogas through the combustor apparently seem to be strikingly affected by the changes in H₂O contents. It is interesting to note that the flame temperature zones change their positions and advance to the burner's downstream. The rise in flame temperatures of the biogas can be attributed to the change in H₂O content caused by a better fuel-air mixture. It is also observed that adding H₂O into the biogas lowers the axial temperature levels.

目前的工作涉及燃烧器中沼气在H ₂ 0含量和H ₂ S的不同条件下的燃烧特性。水（H ₂ O）蒸气的含量已从0％更改为10％，并且在执行数值研究时，已使用CFD代码。在建模中，已经使用了燃烧模型（PDF /混合分数）以及湍流模型（k-Ɛ标准湍流模型）。该研究还通过向沼气中添加不同量的H ₂ O来处理沼气的燃烧性能。通过燃烧室的沼气的排放和火焰温度显然似乎受到H ₂的变化s的显着影响。O含量。有趣的是，火焰温度区域会改变其位置并前进至燃烧器的下游。沼气火焰温度的升高可归因于更好的燃料-空气混合物引起的H ₂ O含量的变化。还观察到向沼气中添加H ₂ O会降低轴向温度水平。
