International technology group ANDRITZ has received an order from Russia’s Ilim Group to supply a new recovery boiler to its Ust-Ilimsk mill in Russia. The ANDRITZ HERB recovery boiler will have a black liquor combustion capacity of 1,950 tds/d, with start-up planned in the second half of 2021.
The order is part of the one billion US dollar “Big Ust-Ilimsk Project” that targets increasing pulp output at the mill by 130,000 tons per year and a finished product capacity increase from 550,000 to 1.5 million tons per year.
The HERB recovery boiler offers high efficiency and availability as well as a modern combustion air system, among other things. It is designed to handle all non-condensable odorous gases generated in the new pulp line in any foreseen operating situation.
In recent years, ANDRITZ has received three major recovery boiler upgrade orders from the Ilim Group, and this new HERB recovery boiler delivery is another example of the excellent long-term relationship between the Ilim Group and ANDRITZ.
