【Abstract】 This paper investigates particulate fouling removal mechanisms, explains the cause for the formation of the phenomenon of the induction step, redefines initiation of fouling, and develops a predictive model of particulate fouling by means of turbulent burst theory. The new model makes a feature of expressing the fouling thermal resistance in terms of easily measurable parameters. The predicted results by the predictive model derived in this paper agree reasonably with the experimental data on ash-air.更多还原
