Heat recovery from:
Chemical and petrochemical industry
Exhaust gases from boilers, heating systems, thermal oxidizers, reactors and flared gas (> 400°C)
Steel and iron industry
About 95% of the heat demand lies in the high-temperature range (> 400°C)
Heat from exhaust gases from boilers (~300°C)
Exhaust gases from rolling mills (~500°C)
Paper-and-pulp industry
Paper mills exhaust air from paper machine dryers, wood refining and grinding processes (~70–80°C)
