摘要
超超临界锅炉作为高效清洁能源转换的重要设备,能够在极高温度和压力下运行,极大地提高了发电效率.然而,在超超临界状态下,水冷壁面临着严峻的高温腐蚀问题,这主要源于其承受的复杂工作应力和恶劣的环境条件.因此,开发有效的抗腐蚀涂层,提升水冷壁的耐久性和可靠性,成为行业内的迫切需求.文章探讨了基于等离子喷涂技术的超超临界锅炉水冷壁抗高温腐蚀的优化,分析了超超临界锅炉及水冷壁的高温腐蚀机理、等离子喷涂涂层的材料选择与结构设计及喷涂参数的优化,并对等离子喷涂技术的发展进行了展望.
Abstract
As an important equipment for efficient and clean energy conversion,ultra supercritical boilers can operate at extremely high temperatures and pressures,greatly improving power generation efficiency.However,in the ultra supercritical state,water-cooled walls face severe high-temperature corrosion problems,mainly due to the complex working stresses and harsh environmental conditions they are subjected to.Therefore,developing effective corrosion-resistant coatings to enhance the durability and reliability of water-cooled walls has become an urgent need in the industry.The article explores the optimization research of high-temperature corrosion resistance of ultra supercritical boiler water wall based on plasma spraying technology,analyzes the high-temperature corrosion mechanism of ultra supercritical boiler and water wall,the material selection and structural design of plasma spraying coating,and the optimization of spraying parameters.It also looks forward to the development of equivalent ion spraying technology.
