Valmet and Shanying International Holdings Co., Ltd. have signed a contract regarding a delivery of a mill waste-fired CFB boiler plant to Shanying Huazhong Paper’s paper mill, in the city of Jingzhou in Hubei province, China. 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. Installation is scheduled to begin in June 2018. 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,” says 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,” he continues.
“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,” says 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.
Technical information about the delivery
Valmet’s 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 totaling to 260,000 tons of waste annually. Light fuel oil is used only for start-ups. The chlorine and alkaline content in the waste derived fuel is relatively high, but using Valmet’s circulating fluidized bed technology the emissions are controlled efficiently.
