Research On Anti-abrasion Technology Of Water-Wall Tubes In Circulating Fluidized Bed Boiler

Although CFB boilers possess advantages such as suitability for types of coal, high combustion efficiency, low pollution as well as good performance of control, the abrasion of water-wall is very severity, which impact the safe and economic operation of unit. The thesis has further studied on abrasion mechanism of the water-wall and the influence factors and carried on the examination to the abrasion condition of our company's #1 CFB boiler water-wall, meanwhile analyzed the abrasion characteristic of the water-wall.Proposed anti-abrasion technology of water-wall, and implemented the synthesis anti-abrasion measures to the water-wall tubes. Carried on the contrast analysis to the abrasion condition of water-wall before and after adopting anti-abrasion technology. Result is indicated that the measure has well resolved the serious problem of water-wall abrasion, realized the stability operation of the boiler, whose economy and social benefits are notable.
