High-Efficiency
Heat Transfer Solutions

LJUNGSTRÖM is a global leader in air preheater and heat exchanger technology designed specifically for power generation environments.

Our systems help power plants:

• Reduce stack temperature and flue-gas heat loss
• Improve boiler efficiency and unit heat rate
• Lower fuel consumption per MWh
• Increase net plant efficiency using existing assets

By recovering energy that would otherwise be wasted, power producers unlock immediate performance gains.

Advanced Manufacturing
Built for Power Generation

LJUNGSTRÖM’s vertically integrated advanced manufacturing capabilities eliminate supply-chain uncertainty for critical power plant components. 

Benefits include: 

• Shorter and more predictable lead times 
• Precision manufacturing of large, complex components 
• Tight quality control from design through fabrication 
• Reduced outage risk for schedule-critical replacements 

With in-house manufacturing, power plants receive fit-for-purpose components built to perform in harsh operating conditions. 

Supporting Emissions Reduction
and Future-Ready Power Generation 

Improving heat transfer efficiency is one of the most effective ways to reduce emissions without changing fuel sources. 

LJUNGSTRÖM solutions help power plants: 

• Reduce CO₂ emissions 
• Lower overall fuel burn 
• Improve readiness for carbon capture and energy transition upgrades 

Efficiency improvements today create flexibility for tomorrow’s regulatory and operational demands. 

Regenerative
Air Preheaters 

LJUNGSTRÖM Regenerative Air Preheaters are the industry benchmark for improving boiler efficiency and reducing fuel consumption. With decades of proven performance in high-temperature, ash-laden environments. LJUNGSTRÖM Regenerative Air Preheaters have a long service lifespan with upgradeable internal parts and are also compatible with modernization and retrofit programs.

Designed for various types of power plants, biomass and waste-to-energy facilities, utilities, and industrial boilers to:

• Recover heat from flue gas to preheat combustion air 
• Lower stack temperatures and reduce heat loss 
• Improve boiler efficiency and unit heat rate 
• Reduce fuel usage and CO₂ emissions 

Guide & Support Bearings
for Air Preheaters 

Bearing failure is one of the most disruptive risks in rotating heat transfer equipment. We aim to reduce risk of catastrophic air preheater failure, prevent collateral damage to rotors, seals, and castings, and improve the reliability of aging assets.

LJUNGSTRÖM guide and support bearing solutions:  

• Designed for continuous operation under high loads 
• Engineered for thermal expansion and alignment tolerance 
• Available as replacement or upgraded designs 

Waste Heat Recovery Systems  

Every power plant generates recoverable thermal energy. LJUNGSTRÖM systems capture that energy and turn it into usable value. Our Waste Heat Recovery Systems are designed for boiler exhaust streams and turbine exhaust and auxiliary systems, that integrate with existing plant infrastructure.

Waste heat recovery solutions can:  

• Produce steam for auxiliary processes 
• Offset fuel consumption 
• Improve overall plant efficiency 
• Support emissions reduction initiatives 

Advanced Manufacturing for Power Generation Components 

LJUNGSTRÖM provides vertically integrated advanced manufacturing for large, complex, and outage-critical power generation components—helping plants reduce lead times, ensure precise fit, and lower execution risk during maintenance and replacement activities.

Manufacturing capabilities include:

• Large-scale structural fabrication for power plant applications 
• Precision machining and assembly of critical components 
• Bearings, shafts, rotors, casings, and internal assemblies 
• Custom components manufactured to OEM specifications or reverse-engineered designs
