SRB-5 Refurbishment Work Has Been Completed in Koryazhma
The work for the technical refurbishment of soda recovery boiler unit SRB-5 of the affiliate branch of AO Ilim Group in Koryazhma has been completed.
The work was initiated in 2019. The COTES Engineering team has developed an investment application as well as detailed and basic design documentation. Field supervision was assigned a key role. New soda recovery boiler by Andritz (Finland) was placed to the cell of the old boiler next to the existing equipment, and new transit utilities and auxiliary equipment providing rated parameters of the soda recovery boiler were placed. At the same time, structural designs of the boiler frame were adapted, sites for the safe boiler maintenance were designed, and the required reinforcement was made as per the calculations.
The startup of the soda recovery boiler was made in March 2021. Currently, the boiler is operated in a standard mode, and its design power is achieved.
