Chemical recovery boilers

ANDRITZ provides chemical regeneration processes for all pulping technologies.

The chemical recovery boiler is an essential part of the pulp production process as it recovers and regenerates cooking liquors. The challenge is to select a recovery boiler that not only recovers chemicals and generates power efficiently, but also does this in a safe, reliable, and environmentally sound process.

ANDRITZ chemical recovery boilers offer designs capable of maximizing the production of green energy, with minimum emissions, while also recovering chemicals efficiently for the fiberline.

ANDRITZ supplies complete chemical recovery boiler plants, typically on an EPC basis (Engineering, Procurement, and Construction of the entire system, including support structures, boiler house, and automation). Alternatively, the recovery boiler plant can be delivered as an EP project, in which case erection and installation work are performed by others. If requested, ANDRITZ is also able to deliver the “bare boiler” only, i.e. all pressure parts of the boiler. In that case, other equipment and sub-systems can be engineered in co-operation with the customer.
