| Abstract (English): |
The promotion of biomass stoves in rural areas represents a crucial step in the implementation of a rural revitalization strategy and the advancement of clean heating practices in northern rural regions. Nevertheless, household stoves in rural areas continue to encounter challenges, including low combustion temperature and poor combustion stability. In order to address these issues, this study evaluates the impact on combustion from three distinct perspectives: the types of fuel employed, the ratios of primary and secondary air supply, and the excess air coefficients. The study selected three common biomass fuels for analysis: corn, poplar, and rosewood. Four primary to secondary air supply ratios (5: 5, 6: 4, 7: 3, 4: 6) and four excess air coefficients (1, 1.1, 1.2, 1.3) were subjected to experimental testing. The results demonstrated that rosewood exhibited the most optimal combustion temperature and high-temperature duration, thus being designated as the premium fuel. The experiment revealed that when the primary to secondary air supply ratio was 6: 4 and the excess air coefficient was 1.2, the fuel combustion temperature was the highest and combustion stability was the most stable. The findings of this study serve as a valuable reference for subsequent optimization of the combustion environment in biomass stoves. [ABSTRACT FROM AUTHOR] |

推广生物质炉具在农村地区的应用是实施乡村振兴战略、促进北方农村清洁取暖工作的重要 举措。然而, 目前农村户用炉具仍存在燃烧温度低、燃烧稳定性较差的问题。针对上述问题, 从燃料种 类、一次送风和二次送风比例、过量空气系数 3 个角度评估其对燃烧的影响。研究选用了玉米、杨木和 红木 3 种常见的生物质燃料, 实验测试了 4 种一次和二次送风比例 (5:5、6:4、7:3、4:6) 及 4 种 过量空气系数 (1、1.1、1.2、1.3)。结果显示, 红木在燃烧温度和高温持续时间上表现最佳, 被选为优质 燃料。实验确定, 当一次送风和二次送风比例为 6∶4, 过量空气系数为 1.2 时, 燃料燃烧温度最高、稳 定性最好, 锅炉运行效率达到 81%, NOX 排放低于 150 mg/m 3。研究结果为后续生物质炉具燃烧环境 优化提供了重要参考。 [ABSTRACT FROM AUTHOR] |
