摘要: 根据某电厂300 MW燃煤锅炉除尘方案进行技术经济比较,通过低低温除尘器、电袋复合除尘器比较可知,低低温除尘技术具有烟气适应性、节能降耗和不产生固体废弃物等优点。低低温电除尘技术改造工程量大于电袋复合除尘技术,但二者投资费用相当,低低温除尘技术单位运行成本优于电袋复合除尘技术。

Abstract: In this paper, the technical economic performance of low-low temperature electrostatic precipitator(ESP) and combined electro-bag filter are compared for the improvement of the 300-MW coal-fired boiler of a power plant. The comparison result shows that the low-low temperature ESP has the advantages of better adaptability to different flue-loads, more energy saving, emission reduction and no solid emissions. The installation of low-low temperature ESP will take more effort than the combined eletro-bag filter although the investment expenses of these two technologies are approximately the same. Therefore the unit costs of low-low temperature ESP is lower than that of the combined eletro-bag filter.

Key words: coal-fired power, dust removal, technical analysis, economic analysis
