摘要/Abstract

摘要： 建立了催化剂颗粒在烟气轮机叶片表面沉积粘附模型，将催化剂颗粒与叶片表面的碰撞处理为理想弹塑性球体与刚性平面的碰撞进行数值计算. 结果表明，模型预测的催化剂颗粒在烟气轮机叶片表面沉积粘附的部位与实际工况一致，所建模型可有效地预测催化剂颗粒沉积粘附的发生部位.

Abstract: A model of catalyst particles deposition and adhesion on the blade surface of flue gas turbine was promoted, treating the collision between catalyst particles and the blade surface as elastic-perfectly plastic spheres collision with rigid plane, which was used as the basis of numerical calculations. The results showed that the location of catalyst particles deposition and adhesion on the blade surface of flue gas turbine predicted by the model was consistent with the location of deposition and adhesion found in actual conditions, proving that the model can predict the occurrence location of the catalyst particles deposition and adhesion effectively.

Key words: fluid catalytic cracking, flue gas turbine, particle, deposition, model
