Valmet will supply a boiler upgrade and a flue gas cleaning system to Stora Enso’s Anjala-Ingerois sites in Finland. The goal of the investment is to reduce the emissions and to ensure flexible use of different fuel mixtures in heat production, as well as to achieve better boiler performance and higher boiler efficiency.
The value of this kind of boiler rebuild is typically around Euro 15-20 million. The boiler outage is scheduled for the 3Q 2022, but the installation work of the new baghouse filter will be done mainly before the shutdown. The project’s focus has been in finding ways to minimize the boiler shutdown time.
Valmet’s delivery includes an upgrade to an existing biomass and solid recovered fuel (SRF) fired BFB boiler, with a thermal power of 110 MWth. Maintenance type of replacements will be part of the work. The air emission control system modification includes an efficient new baghouse filter with additive feeding.
