Heat recovery systems

Heat recovery reduces energy costs

The main purpose of heat recovery system is to replace primary energy with reclaimed heat from the process in an economically profitable way. Metso heat recovery systems provide excellent scope for achieving this goal – usually with short payback times. The system also improves the quality of environment by reducing the primary steam consumption in addition to reducing droplet and mist formation and removing a major part of exhaust air moisture.

Metso heat recovery system can be used to heat for example:

• Dryer section supply air
• Fresh water
• White water
• Machine room ventilation air

If you suspect that your heat recovery system is not performing properly, let our process survey group analyze your system and recommend what can be done for heat recovery optimization.

Main benefits of Metso Heat recovery system:

• Cost savings and lower environmental load from power production
• Less fresh water consumption because the process is more closed, as evaporated water is returned to the system
• Reduced exhaust plume formation when water vapor is condensed from exhaust air
• Heat recovery equipment acts as a silencer => Less requirement for sound attenuation
• Washing units for heat exchangers prevent blocking and maintain efficient heat transfer
• Metso heat recovery system provides the best return on investment with short payback times
  

  Sappi Kirkniemi cuts coating machine (CM 3) drying costs

   

  “Working together with Metso we improved the energy efficiency of coating machine 3,” says Matti Korhonen, Assistant Process and Quality Manager. “We have been very pleased with the results. We are now using close to 20% less gas-generated energy for drying coating than before.” Read more
