The Austrian company will replace the biomass boiler’s existing electrostatic precipitator (ESP) with a new one equipped with a switched integrated rectifier (SIR). The new solution will have significantly lower emissions and power consumption than the previous system.

The new ESP will be installed using the existing steel support structure, which will reduce the construction effort and speed up the project. Andritz’s scope of supply comprises the ESP including the SIR for the power supply and the ducts. Start-up of the new system is scheduled for August 2024.

Andritz has delivered more than 30 ESPs for biomass plants over the past 15 years.

Skellefteå Kraft is one of Sweden’s largest power producers from renewable sources, mainly wind, hydro power, and biomass.
