Recovery Boiler Rebuild
Valmet has upgraded a significant number of power and utility boilers worldwide, with excellent results. We have all the necessary know-how and resources to provide you with expert assistance and to manage complete projects, all in the shortest possible time frame.
Increased capacity
Capacity increases of up to 40% are common, and our rebuilds are typically planned and carried out in a very short time frame. Valmet has developed long-standing relationships with pulp mills all over the globe. We have upgraded more than 200 chemical recovery boilers, with excellent results.
Environment
As with other rebuilds, the environment often comes out a winner. For instance, low-odor conversions reduce emissions of malodorous gases, while other upgrades lower emissions of NOx. Increased production by 34% and decreased levels of NOx by 30% was the result of a rebuild carried out by Valmet.
The results of our recovery boiler rebuilds are:
- Increased capacity
- Improved environmental performance
- Increased safety
- Higher availability
