Surface energy loss from white cement kilns is approx. 15-20% of the energy input to the kilns. Annually this equals approx. 1200TJ of energy or almost 20% of the total district heating energy in the city of Aalborg.
The surface loss from cement kilns is high and is not captured for other purposes.
They are looking for solutions to prevent energy from leaving the kiln tube and/or solutions to utilize this energy for district heating, ORC systems, electromechanical cells, etc.
