气力除灰实际应用中应注意的事项

Considerations in pneumatic ash removal practices

目前,国内大型火电厂基本上实现除灰系统的国产化,但由于气力除灰系统本身的复杂性,我国大型火力发电厂在气力除灰系统的实际运用中仍然面临一些问题。文章将从如何保证系统运行顺畅和出力正常,节能降耗与布袋除尘器的除灰系统设置,低温状态除尘器下的封闭及输灰管道的保温这3个重点出发进行研究和探讨。

Nowadays,localized pneumatic ash transportation technologies have been applied in domestic large-scale thermal power plants.However,there are some problems in application of pneumatic ash transportation system in Chinese large-scale thermal power plant,due to the complexity of pneumatic ash transportation system.This article discusse on howto keep system stably and effectively,energy saving and the system settings of bag-type dust remover,the sealing of dust remover and heat preservation of ash conveying pipeline in lowtemperature situation.
