摘　　要：大型对冲布置旋流燃烧方式锅炉通常采用大风箱结构,即根据锅炉容量和制粉系统的不同,若干只燃烧器安装在同一二次风箱内。电厂发现,每次检修风箱都出现大量的积灰,除灰问题耗费了大量的人力财力物力。为减轻或解决这一问题,本文用数值模拟计算的方式探讨了在风箱内设置防积灰导流板的可行性。Large hedge arrange swirl combustion boilers adapt large windbox. According to the boiler capacity and the system of powder system, several burners are installed in the same windbox. The power plant find, when checking the windboxes, there is a large amount of ash, It consumes a lot of manpower and financial resources. To alleviate or solve the problem. In the paper, the feasibility of setting up anti -ash guide vane in windboxes is discussed by numerical simulation.
