High temperature convective heat exchange surfaces are damaged by dust erosion and their function is impaired by dust deposition.

A novel heat exchange surface is presented in this paper which minimizes deposition on, and erosion of, boiler tube passes in fossil fuel fired units. This is accomplished by removing particulate phases from an air stream. A mathematical model is used to analyze this modified boiler tube. This demonstrably conservative predictor indicates that essentially all the material entrained in the gas stream entering a ten tube bank of the particulate precipitating heat transfer surface can be removed. Additional investigations are presented which demonstrate that there is no measurable difference between the heat transfer effectiveness of a conventional boiler tube and the “flow separator and heat exchanger.”
