摘　　要：在燃煤电厂冲灰水闭路循环系统中,水力输灰管和回水管的结垢是所需解决的主要问题。阐述了燃煤电厂冲灰水闭路循环系统结垢的机理、主要影响因素,介绍了目前国内外冲灰系统防垢、除垢的方法,并展望了冲灰水闭路循环系统的防垢技术的发展。In the closed circulation system of ash-sluicing water of coal-fired power plant, the scaling of the hydraulic ash transport pipes and the backwater pipes is the main problem that need to be solved. The mechanism, the main factors which influence the scaling in the closed circulation system of ash-sluicing water of coal fired power plant were elaborated, meanwhile, the method for scale prevention and removal in China and abroad was introduced with the development of the scale prevention technology for closed circulation system of ash-sluicing water prospected.
