摘要
提出了3种不同的扬料加热器结构，截面结构分别为正三角形、A型直角三角形及B型直角三角形，仿真模拟分析了此3种扬料加热器结构下脱硫石膏的速度场、温度场、温度稳定时间及平均温升效率。并将模拟结果与试验数据进行对比。结果表明，在相同条件下，A型直角三角形扬料加热器的扬料效果与加热效果优于其余2种扬料加热器结构。
Abstract
Through analysis,three different kinds of lifting heater structure are proposed,with cross-sectional structure being regular triangle,A-type right triangle and B-type right triangle respectively.The flue gas desulfurization (FGD) gypsum's velocity field,temperature field,temperature stabilization time and average heating efficiency under these three lifting heater structures are separately simulated and analyzed.The simulation results are compared with the experimental data.It is found that under the same conditions,the lifting effect and heating effect of the A-type right triangle lifting heater are better than those of the other two kinds of lifting heaters.
