Heat recovery from paper machine

Heat recovery from paper machine and delivery to distrct heating netowrk with heat pumps.

The challenge:

Heat recovery for district heat network with a free flow design on exhaust gas side.

Exhaust gas from paper drying machine is fully saturated with water at 55 ℃ C

Low pressure drop on gas side in order not to interfere with production

High condensation rate. Heat exchanger to handle fouling.

The solution:

A long, flue gas condenser with CIP nozzles

In operation since 2012. Only limited maintenance since installation

The heat recovered is boosted with heat pumps for local district network.
