本研究は、バイオマス発電所の燃焼プロセスをAspen Plusでシミュレーションし、過剰空気量が燃焼温度やガス排出に与える影響を分析した。理論空気量に近い条件で最高燃焼温度1616.15℃を達成し、CO削減・CO2増加により完全燃焼に近づく一方、過剰空気はNOx低減に有効だが断熱火炎温度を下げることを示した。バイオマス燃料の特性に応じた最適な空気比の重要性を提起している。
English
This study simulates the combustion process of a biomass power plant using Aspen Plus, analyzing the effect of excess air on flame temperature and gas emissions. Near-stoichiometric air achieves maximum combustion temperature (1616.15°C) and more complete combustion (lower CO, higher CO2), while excess air reduces NOx but lowers adiabatic flame temperature. The findings highlight the importance of optimizing excess air for different biomass fuels to support net-zero goals.

📄 Abstract（原文）
Abstract The utilization of biomass as an alternative energy can support the achievement of Net Zero Emissions. Each type of biomass fuel can provide different combustion effects from one another. This is due to the different heating values of each fuel. The calorific value is one of the things that affect the combustion performance of the biomass power plant. The main purpose of this study is to examine how different amounts of excess air used during the combustion process affect the outcomes. Combustion is a chemical reaction involving decomposition and gasification that simultaneously occurs in a space where a large amount of energy is released. The modeling and simulation of the decomposition and gasification processes were carried out using Aspen Plus. In this simulator, the decomposition process takes place in the Yields Reactor, while the gasification process occurs in the Gibbs Reactor. The biomass and ash components are characterized by their ultimate, proximate, and sulfur analysis. Then the excess air is varied to analyze its impact on the flame temperature from the reaction. The simulation findings emphasize crucial considerations for achieving complete combustion and reducing harmful gas emissions. Maintaining excess air close to the stoichiometric level ensures maximum combustion temperature at 1616.15 °C while minimizing excess air reduces NOx gas concentration. Approaching stoichiometric air level decreases CO gas and increases CO 2 , indicating more thorough combustion. However, excess air leads to lower adiabatic flame temperature due to nitrogen formation.
