Industry operating characteristics
Fuel chemistry, ash transport, flue-gas treatment and heat transfer create different exposures along one generation train.
Industry applications
Power & Energy
Condition-based protection for boilers, flues, gas-treatment equipment, heat exchangers and thermal pipework.
Typical process and equipment systems
Combustion, steam generation, heat recovery, emissions control, ash handling and cooling systems must be reviewed as connected assets.
Typical equipment
Operating environment and conditions
Environmental exposure
Hot flue gas and ash
Acidic condensation during cooldown
Wet gas-treatment zones
Operating conditions
Continuous thermal duty
Load changes and shutdown cycles
Restricted tube-bank access
Why the problems form
Ash particles, local gas chemistry, cooldown condensation and thermal gradients can combine at waterwalls, tube banks, flues and treatment equipment.
High-temperature oxidation
Typical equipmentBoiler · waterwall · tube bank
Heat, cycling and the local gas atmosphere accelerate oxidation at exposed surfaces and joints.
Scale, cracking and local loss of the protective barrier can increase maintenance exposure.
View solutionCondensation and under-film corrosion
Typical equipmentFlue · heat exchanger · stack
Moisture collects at cold spots, welds, supports and poorly drained details.
Blistering, pitting and hidden corrosion can spread beyond the visible defect.
View solutionChemical-medium attack
Typical equipmentDesulfurisation · scrubber · wastewater
Identified acids, alkalis, salts or process liquids can penetrate incompatible or discontinuous films.
Softening, discoloration, loss of adhesion and substrate attack can develop around defects.
View solutionParticle wear and erosion
Typical equipmentFan · ash pipe · hopper
Particle size, speed, impact angle and concentrated flow remove material unevenly.
Thinning, grooves and local perforation can disturb flow and shorten service intervals.
View solutionHeat loss and hot surfaces
Typical equipmentBoiler casing · steam line · hot duct
Exposed surfaces, damaged insulation, supports and complex geometry create thermal paths.
Uneven surface temperature and heat loss can affect access, process stability and energy use.
View solutionOperational impact
- Tube or duct surface loss
- Reduced heat-transfer reliability
- Maintenance pressure during outages
Protection objectives
- Map gas, ash and condensation exposure
- Control coverage on complex geometry
- Coordinate protection with outage planning

View caseIndustry FAQ
What information is needed to review protection in Power & Energy?
Provide the equipment location, substrate, medium, operating state, visible high-temperature oxidation signs, access and maintenance constraints. The review must begin with the actual service condition.
Which Power & Energy equipment should be inspected first?
Prioritise assets such as Boiler · Chimney and flue · Desulfurization equipment · Pipeline where exposure is concentrated, coating condition is changing or access is only available during shutdown.
Can an old coating be overcoated in Power & Energy service?
Only after adhesion, contamination, moisture, defects and compatibility are assessed. Loose or chemically affected layers around high-temperature oxidation zones must not be buried.
How should combined corrosion and wear be handled in Power & Energy?
Map where each mechanism dominates, especially around high-temperature oxidation areas, then define preparation and a compatible layered system for each zone.
How is application quality checked for Power & Energy equipment?
Use traceable preparation records, environmental checks, coverage and defect inspection, confirmed hold points and the protection objective: map gas, ash and condensation exposure.
What should a maintenance plan for Power & Energy include?
Record repeatable inspection locations on Boiler · Chimney and flue · Desulfurization equipment · Pipeline, changes at welds, edges and repairs, and correct local damage before it spreads beneath the surrounding system.
