声波除灰装置利用声波与烟气逆向流动 ,烟气流在声震荡作用下产生不稳定流动使灰粒难以在管壁表面沉积 ,进而烟气将灰粒带出锅炉 ,达到除灰目的。NP系列声波除灰装置在秦皇岛发电有限责任公司锅炉上的应用实践证实了该声波除灰装置具有除灰效果优异、运行安全可靠、节能降耗、维护及操作简便等特性 The sonic ash removing device utilizes the sonic wave and the flue gas to reversely flow, and the flue gas flow generates unstable flow under the sound oscillation to make the soot difficult to deposit on the surface of the pipe wall, and the flue gas takes the soot out of the boiler to achieve the purpose of removing ash. The application of NP series sonic ash removing device in the boiler of Qinhuangdao Power Generation Co., Ltd. confirmed that the soot removing device has the features of excellent ash removing effect, safe and reliable operation, energy saving, easy maintenance and simple operation
