Process upgrades for chemical recovery

High-yield, low-cost rebuilds and upgrades can help you stay competitive, achieve environmental goals, and increase the service life of your assets as 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 service

Upgrades to increase capacity, protect the environment and allow fuel flexibility

Valmet's goal is to maintain the competitiveness of our customers' core processes and to develop them throughout their lifecycles. Valmet provides energy producers with a wide range of solutions for upgrading and enhancing processes and machinery. The scope is always based on each customer’s specific needs and tailored solutions to maximize the performance of different processes.

Valmet's expertise and experience is incorporated in all our products, giving us unparalleled insight into all aspects of upgrading processes and machinery. We are committed to continuously researching and developing new technologies, materials and designs to enhance the performance of existing equipment and processes. 

We help you recharge your CFB and BFB boilers to:

  • Improve capacity
  • Reduce emissions
  • Extend lifetime
  • Ensure availability
  • Enhance energy efficiency
  • Improve water circulation
  • Allow fuel flexibility
We have all the necessary know-how, based on experience and resources, to manage complete projects and provide you with expert assistance, within the shortest possible time frame.

Convert old boiler to extend 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 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
