Waste heat recovery from Industrial Dryers

Fouling and corrosion problems limit heat recovery. Polymer economisers and air preheaters are corrosion resistant and have in-line cleaning.

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.
