【摘要】 “四管”(指水冷壁管、过热气管、再热器管和省煤气管)的高温腐蚀和磨损是造成工业应用中锅炉管道失效的原因之一。在分析锅炉管道高温冲蚀机理的基础上,综述了国内外锅炉管道高温防腐技术的研究现状和前景,采用各种热喷涂及刷涂技术,选择适当的涂层材料,可以有效控制高温冲蚀磨损,延长锅炉管道的使用寿命,是目前一种经济、可行的途径。更多还原

【Abstract】 The high temperature erosion and wear in the four tubes is one of the factors of boilers’invalidation in industrial application.Nowadays,one economic and feasible way is using some kinds of thermal spraying and brush- ing to effectively protect boiler tubes from high temperature erosion wear with suitable coating materials,which make the use of boiler tubes longer.In the present paper,the high temperature erosion mechanism is analyzed,as well as the boiler tubes’high temperature erosion prevention technology is reviewed.更多还原
