Abstract Five types of available high-volatile fuels from different origins were burnt under a variety of operating parameters in bubbling bed to explore the emission characteristics of N2O and NOX. The main operating parameters studied were bed temperature, excess air ratio, fuel particle size, and bed material size. It was found that the N2O emission decreased as the temperature increased while the NOX emission was incompletely the same. Both the N2O and the NOX emissions increased with the increasing excess air ratio. Two series of fuel particle size experiments showed the opposite results, indicating that the influence of particle size on the N2O emission depended on fuel types. The N2O emission decreased and the NOX emission also increased with the increasing bed material size. After devolatilization, N2O and NOX emissions decreased and devolatilization had a greater impact on N2O. Moreover, devolatilization had a greater impact on N2O, which could obviously reduce N2O and NOX emissions.

鼓泡床燃烧中五种高挥发分燃料N2O和NOx排放特性的实验研究

摘要 将5种不同来源的可利用的高挥发分燃料在鼓泡床中在不同的运行参数下燃烧，以探索N2O和NOX的排放特性。研究的主要操作参数是床层温度、过量空气比、燃料颗粒尺寸和床层材料尺寸。结果表明，随着温度升高，N2O 排放量减少，而 NOX 排放量不完全相同。N2O 和 NOX 的排放都随着空气过剩率的增加而增加。两个系列的燃料粒径实验结果相反，表明粒径对 N2O 排放的影响取决于燃料类型。随着床料尺寸的增加，N2O 排放量减少，NOX 排放量也增加。脱挥发分后，N2O 和 NOX 排放量减少，脱挥发分对 N2O 的影响更大。此外，脱挥发分对 N2O 的影响更大，可以明显减少 N2O 和 NOX 的排放。
