火电厂粉尘污染机理及防治措施探讨

Discussion of the pollution mechanism and preventing measures to the thermal power plant dust

要关注在火电厂设计工作中，应加强对新工艺设备如正压气力除灰系统和烟气脱硫系统的粉尘产污环节的分析，并制定提出符合实际、并且有效的环保措施。加强在灰库处、输煤系统扬尘点较多，扬尘范围大，粉尘浓度超标的地方，采取相应的除尘措施。

In paying attention to the thermal power plant design, it is necessary to strengthen the analyzing to the new process equipment dust pollution link such as pneumatic ash disposal system with positive pressure system and flue gas desulphurization system and to formulate practical and effective environment protection measures. In the place of dust bank, coal handling system, flying dust - forming points and dust concentration over - standard, it is necessary to adopt relevant dust removal measures.
