Careers How did HVTS Cladding Protect 2,000 Sq. Ft. of Boiler Tubing from Fireside Corrosion in 5 Days?
Scheduled Shutdown
The unit was in a scheduled outage in October 2019, at which time the fireside of the tubes in the boiler were inspected by robotic UT. Wastage was discovered on both sidewalls above the existing field applied overlay, rear wall slope and burners, and front wall slope and burners. The type of damage is typical for opposed wall fired pulverized coal boilers operating in a reducing atmosphere with low NOₓ burners.
Rapid Response
IGS’ HVTS Cladding service was used to install 5450 EPRI Proven HVTS Alloy Cladding over the damage zones. IGS offered a rapid response and addressed the areas during the week of November 4, 2019. The IGS solution is a rather fast application – a total of 2,000 square foot of boiler tubing was protected with HVTS in 5 short days.
