Pulverized Coal (PC) Fired Boilers

IGS’ Metalspray™ and Automated Weld Overlay services, applied either on-site or in our shop for subsequent installation, are frequently employed to address problems associated with: (i) corrosion from the reducing atmosphere and flame impingement in lower furnace zones, (ii) sliding wear and erosion on aperture and lower slopes, (iii) sootblower wastage and coal-ash corrosion in superheater, reheater, and economizer sections, and (iv) a variety of other applications, including coal chutes, induced draft (ID) fans, booster fans, and coal mills. Additionally, our Mechanical Services group has considerable experience repairing and replacing water-wall panels, boiler tubes, coal nozzles and tips, valves and doors, and tube shields.
