大型电除尘器与电袋除尘器技术经济比较

Comparison of Technical Economy between Big-sized Electrical Precipitator and Electrical Bag Precipitator

以某300MW火电机组配套除尘设备为例,从一次性投资、维护费用和运行费用等方面对电除尘器和电袋除尘器进行了技术经济比较,结果表明,当粉尘排放浓度≤50mg/Nm3时,选用电除尘器较适宜,但对更加严格的排放标准,选用电袋除尘器更好。

By taking a 300MW power generating set with precipitation equipment as an example,Comparison of technical economy between big-sized electrical precipitator and electrical bag precipitator is made from the costs such as lump-sum investment,maintenance expenses and operation costs.The result shows that when the concentration of dust emission is ≤50mg/m3,electrical precipitator is chosen,but when a strict emission standard is implemented,then it is much better to choose electrical bag precipitator.
