Optimization Study on High-temperature Corrosion Resistance of Ultra Supercritical Boiler Water Wall Based on Plasma Spraying Technology
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.
