On November 26, 2019, the on-site observation and technical exchange activities of Guangdong Shuang hydropower plant were successfully concluded! It has been running for 10 months from the last time of boiler opening to this time of maintenance. In a dense phase area, the coating of water-cooled wall pipe transportation has disappeared, and the base metal of the pipe wall has been thinned by 2mm, so the pipe can only be changed, and the pipes that have been used for more than 3 years in the same part by laser cladding almost have no wear! The laser cladding tubes used in other areas with severe wear are also effective! Laser cladding wear-resistant technology provides a strong guarantee for the stable and long-term operation of double water boiler! Brief introduction to the operation of double water boiler: 480 ton CFB boiler of Harbin boiler, mixed with 10% wet sludge, with high ash content, full load and annual operation of nearly 7800 hours, the water wall is seriously worn. In the most worn part (spraying or surfacing can only be maintained for 3-6 months), the laser cladding wear-resistant technology of Huadian degar has been used for 6.5 years, and the parts with severe wear-resistant have been replaced by more than 700 Huadian degar in batches All of the water wall tubes were in normal operation.
