摘要: 为实现燃煤电厂烟尘超低排放,介绍了一种燃煤电厂烟气处理系统协同治理技术路线,分析了该协同治理技术路线烟尘协同效应的机理及特点,重点对烟尘排放在不采用湿式电除尘器时达到<5 mg/m3及<10 mg/m3的协同治理技术的理论和实践进行了研究和探讨,提出了当前利用协同治理技术达到烟尘超低排放的推荐性技术配置方案,相关结论可为现阶段燃煤电厂烟尘治理系统的设计与升级改造提供参考。

Abstract: In order to realize ultra-low dust emission from coal-fired power plants, a flue gas synergistic control system is presented and the analysis on the mechanism and characteristics of the system is conducted. The paper focuses on the synergistic control results of dust emissions less than 5 mg/m3 or 10 mg/m3 without wet electric-static precipitators(WESPs). Based on the analysis, the technical allocation plan is recommended for current synergistic control applications. The results can provide reference for the designing and upgrading of coal-fired power plants in the current stage.

Key words: synergistic control technology, emission limit of gas turbine, ultra clean emission, low-low temperature ESP, high-efficiency dust collection WFGD, WESP
