Summary of catalyst particles collision models in flue gas turbine
摘要
Abstract
Aiming at the problem of serious fouling in the flue gas turbine blades,the collision model of particles with smooth wall and rough wall,the deposition model of particles were summarized.According to the fouling process of flue gas turbine,the collisions between the catalyst particles and the blades were summarized into three cases:the collision between the particles and the coating wall,the collision between the particles and the particle wall,and the collision between the particles and the scale wall.Through the summary of these models can be found that when the particles collide with the rough wall,the sinusoidal model regards roughness as a uniform distribution,The virtual wall model is only applicable to the case where the incidence angle is less than 7°,when the roughness angle is treated by normal distribution,the result is the best.For the collision between particles and flue gas turbine blades,the first two kinds of collisions can find a suitable collision model,the collision between the particles and the fouling wall is still to be further studied.关键词
