| 摘 要： | 通过建立滚筒冷渣器的动态实验系统,采用正交实验设计方法测量了排渣粒径、灰渣填充量和滚筒转速对综合传热系数的影响。实验结果表明:3种影响因素中,排渣粒径的影响最大,加料量与转速的影响大小相近,转速的影响最小。综合传热系数随排渣粒径的减小和转速的增大而增大。灰渣填充量较小时,滚筒冷渣器的综合传热随灰渣填充量增大而增大;当灰渣填充量增大到一定数值后,滚筒冷渣器的综合传热系数则几乎不再随灰渣填充量改变。

| Abstract: | A dynamic experimental system was built to study the factors, including particle diameter, ash amount and rotational speed, which influence the complex heat transfer in rolling ash cooler, using the orthogonal design. It was shown that the particle diameter has the greatest effect on complex heat transfer coefficient, but rotational speed has the smallest. The heat transfer in rolling ash cooler could be enhanced by increasing the rotational speed and decreasing the particle diameter. The complex heat trans... |
