Research Progress in Corrosion and Protection of Stack in Wet Flue Gas Desulfurization System of Power Plants
摘 要
湿法脱硫工艺已成为国内外电厂主导的烟气脱硫技术。湿法脱硫后烟气具有强腐蚀性, 带来严重的设备腐蚀问题。本文介绍了湿法脱硫后烟囱的腐蚀环境、腐蚀机理及其腐蚀行为, 综述了国内外电厂脱硫系统烟囱腐蚀控制方法与防腐蚀材料的研究进展, 供设计烟囱防腐蚀措施参考, 有助于提升国内电厂脱硫设备的腐蚀控制水平。
Abstract
Wet flue gas desulfurization (WFGD) is the dominant technology among all kinds of technologies of FGD of coal-fired power plants in the world. The flue gas is highly corrosive after WFGD and thus may cause serious corrosion of equipment. Corrosion environment, corrosion mechanism and corrosion characteristics of the stack after WFGD are described. The research progress in controlling methods and materials for the corrosion of the stack after WFGD at home and abroad is summarized , which provides reference to solve the problem of the stack corrosion of coal-fired power plants at home.
