Process upgrades for chemical recovery solutions

Cost effective and circular way to reach new recovery boiler and evaporation performance targets

High-yield, low-cost qualitative rebuilds and upgrades can help you stay competitive, achieve environmental goals, and increase the service life of your recovery boiler and evaporation plants by costs far below those of new construction.

How to raise the production efficiency or quality to the new level and at the same time lower the maintenance costs?

Process upgrades are small or mid-size investments that opens up production bottlenecks or extends the original process design limitations. Typical process upgrade building blocks are design engineering, new components, new machine and process controls and efficient commissioning and start-up services.

Circular solutions to convert old boilers and plants and  extend the lifetime

Another possibility to meet new requirements is to convert an old boiler to fluidized bed technology. A customized rebuild can often increase the service life of a recovery boiler, an evaporation plant, or a power boiler by ten to 15 years, at costs far below those of new construction.

The main incentives for converting a boiler (CFB or BFB) is fuel flexibility, the possibilities to switch to biomass firing and fulfill stricter emission limits. By converting an old boiler, the investment cost will be far lower, with a faster delivery schedule (about half the delivery time for a new boiler), and easier building permit.  

We have the experience to convert several types of boilers:
  • Grate-fired boilers
  • Pulverized coal boilers
  • Recovery boilers

Evaporation plants upgrade

Valmet offers evaporator technology that provides maximum availability and productivity, minimized operation and maintenance costs - all while complying with strict environmental standards.

• Increased evaporation capacity

• Increased dry solids capability

• Improved operation

• Optimized steam economy

• Improved condensate quality
