Analysis of High Temperature Corrosion Performance of Biomass Boiler Superheater
The high-temperature corrosion performance of biomass boiler superheater was analyzed,and the state of superheater failure pipe,scale sample and rupture situation were studied in combination with actual engineering cases.The curve was developed according to the corrosion law and the change of performance after corrosion.The research results show that the corrosion reaction rate is slow at low temperature,and the corrosion reaction rate increases gradually with the increase of temperature,resulting in cracking,spalling and other phenomena of pipeline failure.In order to prolong the service life of the pipe wall and improve the performance,the research also proposed to shorten the maintenance cycle,temperature control,tube replacement and spraying anticorrosive paint.
