Analysis of Pipeline Abrasion Corrosion in Air Preheater of Boiler No.5
With the popularization of selective catalytic reduction(SCR)systems and the completion of ultra-low emission retrofitting in thermal power plants,some power plants have frequently encountered issues such as abrasion and corrosion in air preheaters,significantly affecting the load ramp-up and safe stable operation of boiler units,and increasing the operational maintenance costs,causing inconvenience to power plant users.Taking the air preheater of Boiler No.5 as an example,this paper conducts in-depth research and analysis on the abrasion and corrosion issues in air preheaters,explores the reasons behind the corrosion,and formulates targeted solutions,providing reference for the prevention and resolution of corrosion issues in air preheaters.
