The new waste-to-energy boiler plant will supply electricity for the paper mill and enables the mill to utilize all of its mill waste in energy production.
The order was included in Valmet’s fourth quarter 2017 orders received. The value of the order will not be disclosed.
Shanying International Holdings says its investment in waste-to-energy solution will enable “high overall efficiency with very effective heat and power generation” and will support circular economy. Installation is scheduled to begin this June, and heat and power production will start early 2019.
“Valmet’s boiler technology offers the highest steam parameters and overall plant efficiency. We expect to achieve high economic efficiency with reduced need for maintenance and production shut-downs,” said Yi Shuai, Plant Director at power plant of Shanying Huazhong Paper. “The tailor-made boiler design meets our expectations of steam parameters which allows us to utilize standard turbine, and we believe it will help to optimize the entire plant.”
“This boiler delivery will be the first paper mill waste-to-energy boiler which has the highest steam parameters. We have developed our waste-to-energy concept especially for this type of power plants. The solution will enable excellent efficiency through high steam parameters even when combusting demanding waste fuels. Utilizing waste in energy production will enable a significant reduction of CO2 emissions compared to fossil fuel powered plants,” said Kai Janhunen, Vice President, Energy business unit, Valmet.
Valmet announced in December 2017 that it will supply an OptiConcept M containerboard making line for Shanying International Holdings.
Its delivery includes major parts of a CYMIC boiler island from fuel silo to boiler outlet. The boiler uses circulating fluidized bed (CFB) technology. The green field boiler plant will use mill waste (paper rejects, pulp rejects and pulp sludge) as its fuel totalling to 260,000 tonnes of waste annually.
