Valmet biomass-fired boiler plant to Segezha in Russia

A Valmet biomass-fired boiler plant and related automation and environmental systems are being installed at the Segezha Group’s pulp and paper mill in the Republic of Karelia, Russia.

The boiler will produce steam for mill production processes and let it use wood residues and sludge as fuel to reduce the use of heavy fuel oil and lower its emissions and environmental impact.

Valmet says the project makes it the leading supplier of bubbling fluidized bed (BFB) boilers with electrostatic precipitator-based flue gas cleaning on the Russian market. This is the third boiler delivery featuring Valmet’s BFB technology to Russia in the past three years. Valmet has delivered numerous biomass- fired boilers as well as chemical recovery boilers to Russia.

The order includes a 90-MW HYBEX BFB boiler with electrostatic precipitator-based flue-gas cleaning equipment, electrification and a Valmet DNA automation system to control and operate the plant.

Valmet says that features of the HYBEX boiler include fuel flexibility, combustion efficiency, reliability, controllability and low emissions. Its main advantage is the ability to use fuels with high moisture content and a low thermal value.

Segezha Group is a vertically integrated holding company that comprises Russian and European enterprises in forest, wood processing, pulp and paper, and paper packaging. It has assets in 13 countries and employs around 13,000 people.
