Valmet has experience with steam separation in many processes since the 80’s. With this experience Valmet has developed a steam separator for the recovery of steam in the Defibrator system. Valmet Steam Separator PV is a mechanical steam separator that separates the steam from the fibers efficiently. A solution that helps to recover energy in the blow line.
Reduction in boiler load
Maximum separation at any production level
Reduces total steam consumption in the system
Eliminates the need of fresh steam for pre-steaming
With Valmet Steam Separator PV it is possible to remove the need for fresh steam to the pre-steaming bin, and as a result reduce the total fresh steam consumption in the system up to 50%. In practice this means that it’s possible to reduce the need for fresh steam going to the Defibrator system and by that save the cost for producing steam that earlier was needed.
|Specific energy||110 kWh/t|
