摘要
介绍通过实验准确测定板式空气预热器空气和烟气在各板面处的对流换热系数ha和hg,再通过努塞尔准数的通用幂函数求得板式空气预热器的压力降损失ΔPa和ΔPg,以便于进行板式空气预热器的优化设计。
The paper introduces convective heat transfer coefficient ha and hg of flue gas each panel and plate air pre-heater air are measured accurately through experiment, then obtained pressure drop loss of plate air pre-heaterΔPa andΔPg by Nusselt number, which in order to optimize design of plate air pre-heater.
