The process will increase the capacity of the recovery boiler and allow for better boiler availability and environmental performance once it’s up and running in mid- to late 2019. 

Ahlstrom-Munksjö is a supplier of fibre-based materials including decor paper, abrasive backings and electrotechnical paper.

The lower part of the boiler will be replaced with a new pressure vessel based on the latest designs for Valmet’s high-performing RECOX recovery boilers. New heating surfaces will be installed to increase the boiler’s heat economy and enable a higher production of steam. Surrounding systems for combustion air, black liquor, smelt and green liquor will also be upgraded.


The delivery to Billingsfors also includes improvements that focus on worker safety and a better working environment in the boiler building, said the company.

“We are very happy and proud to have been chosen as supplier for this important upgrade and are really looking forward to working together with Billingsfors. We will bring the knowledge and technology of Valmet and will combine this with a solid partnership approach that brings the mill’s performance forward,” said Marcus Grundevik, sales manager at Valmet.

Jonas Lindqvist, plant manager, Ahlstrom-Munksjö Paper AB Billingsfors, said, “This project is an important step for Billingsfors to meet the stricter environmental regulations through improved process combustion, reducing local air emissions. This investment is also key for improved efficiency in the mill including lower maintenance costs and higher pulp and insulation paper production.”
