Boiler reliability within short outages

Up to 5× faster protection when every outage day matters.

As coal units are pushed harder, IGS protects vulnerable boiler tubes with HVTS® applied up to 5× faster than alternative cladding solutions. Multi-asset support also covers gas turbines and HRSGs.

Outage speed

Protect more of the boiler within the planned outage.

Power demand is rising, operating horizons are changing and outage windows are not getting longer. When UT reveals a broader damage zone than expected, application speed determines how much risk can be removed before restart.

PC boiler protection

Stop recurring wastage—not only the latest symptom.

Low-NOx combustion, reducing conditions, high-temperature sulfidation and erosion can drive wall loss across waterwalls, slopes, burner zones and superheaters. IGS HVTS® creates a dense, corrosion-resistant barrier without a heat-affected zone or post-weld heat treatment, helping preserve serviceable tube metal and prevent further crack propagation where tube condition permits.

Protect larger damage zones within a fixed outage window
Preserve serviceable tube metal and defer unnecessary panel replacement
Target recurring high-risk areas instead of repeating pad repairs
Document and monitor protected areas for future outage planning

PC boiler case study

2,000 sq. ft. protected in five days.

Robotic UT identified wastage across both sidewalls, the rear wall slope and burners, and the front wall slope and burners. IGS mobilized rapidly and protected the affected boiler tubing within the scheduled outage.

Whole-plant availability

Protect, clean and recover performance across the plant.

Some facilities manage PC boilers, gas turbines and HRSGs across the same site or fleet. IGS supports each asset with a focused solution designed around the actual degradation or fouling mechanism.

01 / PC

Protect boiler tubes with HVTS®

Mitigate fireside corrosion and erosion across waterwalls, slopes, burner zones and superheaters while preserving existing pressure parts.

02 / GT

Stop gas turbine oxidation and spalling

Apply HVTS® superalloy cladding on susceptible compressor discharge and combustor-section surfaces to prevent oxide flakes from damaging downstream components.

03 / HRSG

Clear deep HRSG fouling with PressureWave+™

Where suitable, use controlled, subsonic pressure waves online to remove deep ash deposits, reduce backpressure and recover heat-rate efficiency when fouling limits load, heat transfer or outage flexibility—without abrasive contact with pressure parts.

PressureWave+™ proof

Deep HRSG cleaning completed inside a five-day outage.

At the 282 MW Lodi Energy Center, IGS completed 1,584 PressureWave+™ events across four HRSG sections. The campaign removed heavy rust fouling and debris accumulations up to 25 inches while improving access for future cleaning scopes.
