Heat Recovery efficiency in paper & packaging
In paper & packaging, heat recovery is a major energy cost and a strong efficiency opportunity. Heat recovery captures energy that would otherwise be vented — from flue gas, hot process streams, compressors and refrigeration — and reuses it to preheat feedwater, air or process flows. Matching the grade of recovered heat to a real, coincident demand is the key.
Why it matters in paper & packaging
Pulp and paper is one of the most steam-intensive industries: drying cylinders, recovery boilers, digesters and evaporators run continuously and dominate energy cost. Reliability of large rotating equipment and steady steam supply make it a strong fit for predictive maintenance and energy analytics.
Much of the energy a plant buys leaves as low- and medium-grade waste heat. Recovering even part of it — with economisers, air preheaters, heat exchangers or heat pumps — directly cuts fuel use, and is a core no-regrets step in any decarbonization plan.
The efficiency levers
- Recover flue-gas heat with economisers/air preheaters
- Capture compressor and refrigeration reject heat
- Use heat exchangers between hot and cold streams
- Upgrade low-grade heat with industrial heat pumps
- Match recovered heat to a real, coincident demand
