| 中文摘要: |
| 为探究节煤剂产品特性，本文利用热分析方法讨论了3种节煤剂对煤粉燃烧过程的影响。结果表明，添加不同节煤剂，#1、#2、#3煤样着火点分别降低了9.2 ℃、11.2 ℃和88.9 ℃，并且提高放热效率。燃尽指数表明，节煤剂使#1和#2煤样燃尽性能提高，而#3燃尽性能变差。动力学计算表明，节煤剂能够降低煤粉从着火点到最大燃烧速率阶段的反应活化能，从而提高该燃烧过程的反应速率。 |
| 英文摘要: |
| In order to explore the characteristics of recent coal-saving agents, the influence of three coal-saving agents on the pulverized coal combustion is discussed by the thermal analysis. The results showed that the ignition points of #1, #2 and #3 coal samples were reduced by 9.2°C, 11.2°C and 88.9°C respectively with the addition of different coal-saving agents, and the heat release efficiency was improved. The burnout index shows that the coal-saving agent improves the burnout performance of #1 and #2, while the burnout performance of #3 decreases. Kinetic calculations show that the coal-saving agent can reduce the reaction activation energy of pulverized coal from the ignition point to the maximum combustion rate of temperature, thereby increasing the reaction rate of the combustion process. |
