摘要
分析了影响锅炉风道系统安全经济运行的主要原因 ,并提出了解决方案。在现场消振过程中 ,通过对叶片整流器和阻旋板进行优化设计 ,彻底消除了由于入口集流器和入口风箱内部涡流所引发的风道振动 ,降低了风道系统运行噪音 ,改善了风机叶轮的进气条件 ,使风机运行的经济性得到进一步提高。
The major causes affecting safe and economic o peration of boiler air duct system is analyzed and a solution is put forward in this paper.Through design optimization of director and anti-swirling damper a t site,the air duct vibration caused by vortex flow inside the inlet collector a nd wind box was complet ely eliminated,the noise was also reduced,the air admission condition of fan was im proved,the fans operate more economically.
