| 摘 要： | 对再燃过程中煤粉颗粒在高温烟气中的升温速率,建立数学模型、编程,依据4种粒径(100目、200目、260目、320目筛下煤粉)煤粉颗粒的温度变化结果画出煤粉颗粒在高温烟气中升温和升温速率的曲线图,根据结果与图形分析煤粉颗粒在高温烟气中的升温速率对煤粉的影响,以此提出通过控制煤粉细度降低烟气中NOx排放量的数值模拟研究。

| Abstract: | A mathematic model and programming for temperature rise rate of pulverized coal particles in high-temperature flue gas in reburning process is built.It plots curve of temperature rise rate based on temperature changes of four sizes(100 mesh,200mesh,260 mesh and 320 mesh) of pulverized coal particles in high-temperature flue gas,then analyzes the influence of temperature rise rate of pulverized coal particle in high-temperature flue gas on pulverized coal based on the results and graphs,and consequently prop... |
