小型火电厂中除尘器的选择

Selection of Precipitators in Small Thermal Power Plants

根据最新的火电厂大气污染物排放标准以及各地方强制性规定,新建小型热电厂锅炉颗粒物排放限值执行10 mg/Nm^(3)。在技术性能、投资等方面,对静电除尘器、电袋除尘器、袋式除尘器三种不同除尘方式在小型火电厂中的应用进行研究比较,最终找到适合不同工况、工艺路线小型火电厂的除尘技术。

According to the latest emission standard of air pollutants for thermal power plants and local mandatory regulations,the emission limit of particulate matter for new small thermal power plant boilers is 10 mg/Nm^(3).In terms of technical performance and investment,the application of electrostatic precipitator,electrostatic bag precipitator and bag type precipitator in small thermal power plants is studied and compared,and finally the technology suitable for small thermal power plants under different working conditions and process routes is found.
