Air preheater & Gas-Gas Heater Solutions

Advantages of LJUNGSTROM air preheaters

•  Flexible design options
•  Efficient sealing systems
•  Advanced heating elements and baskets
•  Reduced erection costs

Advantages of LJUNGSTROM gas-gas preheaters

•  Advanced heat transfer
•  High efficiency sealing systems
•  Cleanability & maintenance
•  Easy installation

DN8 -ADVANCED HEATING ELEMENTS

•  Increased thermal efficiency for equal depth in conventional designs
•  Lower operating costs for the same thermal efficiency
•  Lower pressure drops for the same thermal efficiency
•  Even flow distribution
•  Even plant upgrades without affecting your bearing or drive units
•  Extended equipment life & significant long-term savings

TF4 - FULLY CLOSED CHANNEL ELEMENTS

•  Over 10% increased thermal performance for the same depth of element layer
•  3% improvement in thermal performance for equal pressure drop
•  Capable of standing 25% higher sootblowing pressures
•  A lighter and more efficient surface to reduce rotating weight and prolong bearing and drive unit life

PROTEC ENAMEL ELEMENTS

•  Resistant to corrosion, for extended product life
•  High chemical resistance against aggressive flue gas components
•  No need for pretreatment other than degreasing of the steel by rinsing it with hot water containing detergents
•  Resistant to temperatures up to 400 degrees Celsius
•  Superior and homogeneous bubble structure
•  High elasticity and adhesion onto the profiled elements to allow for sufficient packing pressure

LJUNGSTRÖM THERMAL GUARD BASKETS

•  Maximize your air preheater's thermal performance
•  Minimize flow bypass
•  Easily replace your heat transfer surfaces when the need arises
•  Optimize the performance of your plant and save on costs in the short and long-term

EDGE GUARD BASKETS

•  Prolong element life by minimizing the effects of soot-blowing damage to element sheets
•  Improve your bottom line thanks to the cost-effective design of Edge Guard™ basket

OPTIFLEX RADIAL SEALS

•  OptiFlex Radial Seals flexible leaf accommodates pressure differentials and encourages deflection away from the sealing surface
•  Reduced cyclic pressures also lead to a longer operating life and help avoid the premature failure of the flexible leaf portion
•  Utilize the latest generation of our flexible seal technology to significantly lower your hot end air to gas radial leakage in your Ljungström® air preheater

ROTABRUSH ADAPTIVE BRUSH SEALS

•  SAVE ON FUEL - Reduced fuel consumption and imposed plant efficiency due to adequately sealed air preheater
•  REDUCE YOUR CO2 EMISSIONS - Using the RotaBrush Adaptive Brush Seals means less coal burning and less CO2 and other emissions
•  LOWER YOUR FAN POWER - Reduced air preheater leakage leads to lowered fan power consumption, increasing the saleable MWs recovered.
•  AVOID CAPACITY LOSS - Prevent fan limitations when MWs are needed.
•  IMPROVE YOUR APC PERFORMANCE - Better control of your flue gas volumes and temperatures allowing better performance of air pollution control equipment.
•  SAVE TIME AND MONEY - Ingenious replaceable seal cartridge system of RotaBrush™ Adaptive Brush Seals avoids the time-consuming and costly gap setting process
