Waste Heat Recovery

In line with recent developments, the importance of waste heat recovery has risen significantly in the cement industry. The IKN Pendulum Cooler® is predestined for this application.

Especially the recirculation of hot cooling air from the cooler exhaust back into the cooler is possible. The division of the undergrate compartments and the fact that there are no heat sensitive parts under the grate, make the recirculation of hot air possible without drawbacks in that area. Only the cooling fans must be adapted to the thermal load.


Heat Exchanger in Rohrdorf

In Rohrdorf this heat exchanger (air/water and air/oil) is connected to the cooler's mid-air outlet and feeds an electrical power generator with a capacity of over 6 megawatts.
