Valmet has signed a contract to deliver a mill waste-fired boiler plant to Shanying Huazhong Paper's Jingzhou paper mill in Hubei province, China.
Under the contract, Valmet will deliver major parts of a CYMIC boiler island from fuel silo to boiler outlet. The boiler features circulating fluidized bed (CFB) technology.
The green field boiler plant will use mill waste including paper rejects, pulp rejects and pulp sludge as its fuel.
Shanying Huazhong Paper power plant plant director Yi Shuai said: "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.
"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.”
The new waste-to-energy solution will help Shanying International in increasing overall efficiency with very effective heat and power generation while supporting circular economy, Valmet said.
Valmet plans to commence installation of the boiler in June 2018 while heat and power production is scheduled to commence in early 2019.
Valmet Energy business unit vice-president Kai Janhunen said: "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.”
In December 2017, Valmet was selected to supply an OptiConcept M containerboard making line for Shanying International, which is principally engaged in the manufacture and distribution of paper products.
Shanying’s main products comprise various packaging paper boards, corrugated cardboard boxes, culture paper and other paper products.
