Waste heat recovery from Industrial Dryers
Improve dryer efficiency up to 20%
Your Industrial Dryer has additional waste heat recovery potential
Waste heat recovery on Industrial Dryers is limited by fouling or corrosion
Blocked heat exchangers
Heat recovery from the exhaust air stream from a drying process is difficult due to the fouling behavior of dust and product contaminants present. It is a challenge to keep the exchangers clean and to prevent condensate flowing back to the Dryer.
Corroded heat exchangers
The moisture in the exhaust air in combination with corrosiveness of the dried material can create corrosion problems. Carbon steel and even stainless steel will quite often not provide the required corrosion resistance. In food applications the minimum standard is stainless steel.
How to recover more heat from your Dryer exhaust air
Waste heat recovery systems for Industrial Dryers
Polymer Air PreHeater
Warm up drying air by extracting heat from the exhaust air or flue gas. The air preheater is corrosion resistant & anti-fouling and easy to maintain and clean.
Stainless steel or Polymer Economiser
Warm up process water with waste heat from exhaust air or flue gas. The economiser is corrosion resistant & anti-fouling and is easy to maintain and clean.
