扰流棒在提高热传导性能和冷凝水排出过程中的作用

The effect of turbulence bar in increasing heat conduction performance and condensate discharge

扰流棒位于纸机烘缸内部,用来提高热传导,提高干燥均匀度。当扰流棒配置正确,冷凝水达到最佳深度时,采用扰流棒不仅能提高传热速度,还能取得良好的干燥均匀度。本文主要介绍在JOCO 4000试验烘缸内安装扰流棒,从而得出达到最佳性能需要考虑的各种因素。

A turbulence bar inside the dryer cylinder of paper machine, is used to increase heat transfer and drying evenness. When the configuration of the turbulence bar is proper and the condensate is in its optimum depth, the application of turbulence bar can not only increase heat transfer rate but also get the desirable drying evenness. The paper introduces the various factors for achieving the optimum performance when the turbulence bar was installed in the test cylinder of JOCO 4000.
