A theoretical model for predicting the thermal behavior of coal-ash deposits on heat exchangers is desveloped. The heat transfer modes of heat conduction, convection, and thermal radiation are consideredfor the system. The effective thermal conductivities and emissivities of the ash deposits are temperaturedependent. Heat fluxes and dimensionless temperatures in the three layers (loose, sintered, and fused)of the ash deposit are determined. Results are presented for the first two rows of tubes in aligned andstaggered tube banks. 展开更多
