Abstract
Based on the macro check
sample analysis
scanning electron microscope and energy spectrum(EDS) analysis method
the corrosion mechanism of biomass boiler high temperature superheater pipe internal and external surface is studied
and the high temperature superheater corrosion failure reasons are analyzed.Specific measures are taken to ensure the safe and continuous operation of the biomass boiler
to increase the number of hours of effective utilization of the biomass boiler
and to extend the life of the high temperature superheater of the biomass boiler.
