摘要:

部分地方政府出台政策要求燃煤电厂进行白色烟羽的控制,引发广泛关注。为深化白色烟羽控制研究,本文介绍了白色烟羽形成及消除机理,概述了白色烟羽控制技术,包括烟气加热、烟气除水及烟气除水再热,其中水媒式GGH、冷凝器、浆液冷却技术应用最多。进一步,对控制技术进行总结,指出现有控制技术具有一定的局限性,只能在特定环境条件下完全消除白色烟羽。以满足政策要求和环境条件为基础,兼顾技术局限性、工程实际及经济性,提出了技术选择的路线。此外,对环境影响进行了分析,指出白色烟羽控制的环境效益不明显。最后,对白色烟羽控制进行了预测,指出白色烟羽控制需灵活化、差异化、区域化,避免强制化、一致化、全面化。

Abstract:

Some local governments have issued policies to control the white plume of coal-fired power plants, which has attracted widespread attention. In order to deepen the research on white plume control, the formation and elimination mechanism of white plume were introduced, and the control technologies of white plume, including flue gas heating, flue gas dewatering and flue gas dewatering and reheating, was introduced. Furthermore, the control technology is summarized, and it is pointed out that the existing control technology has some limitations, which can only eliminate the white plume completely under specific environmental conditions. On the basis of satisfying policy requirements and environmental conditions, taking into account technical limitations, engineering practice and economy, the route of technology selection is proposed. In addition, the environmental impact analysis shows that the environmental benefit of white plume control is not obvious. Finally, the white plume control is forecasted, and it is pointed out that the white plume control should be flexible, differentiated and regionalized, avoiding compulsory, uniform and generalized.

Key words: coal-fired power plant, white plume, control technology, technology selection, environmental impact
