The new boiler can flexibly use solid fuels such as bark from the mill's debarking process, other wood-based fuels and coal. Together with the mill's current biofuel boiler and Valmet's new boiler it is possible to produce biomass-based energy up to 100%

Valmet's delivery will include a complete circulating fluidized bed (CFB) boiler, and a Valmet baghouse filter. The contract also covers installation, training and commissioning for the equipment. The boiler plant will have a steam capacity of 88 MW. The boiler combines high-efficiency combustion of various solid fuels with low emissions, even when burning fuels with completely different calorific values at the same time.

"Commissioning a boiler plant of this size in 1.5 years is a challenging timetable. This tight delivery schedule is possible thanks to Valmet's standardized CFB boiler design, proper pre-engineering and experienced project team," points out Juha Särkijärvi, Project Manager, Pulp and Energy business line, Valmet.
