Valmet to supply a waste-fired boiler to Shanying Huazhong Paper in China
Finland-headed energy and forest industry technology major Valmet Oyj has announced that it has signed a contract with Shanying International Holdings Co., Ltd regarding the delivery of a mill waste-fired 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.
Shanying International Holdings Co., Ltd., formerly Anhui Shanying Paper Industry Co., Ltd., is a China-based company, principally engaged in the manufacture and distribution of paper products. Its investment in waste-to-energy solution enables high overall efficiency with very effective heat and power (CHP) generation and supports the circular economy.
According to a statement, installation work is scheduled to begin in June 2018 with heat and power production to start early 2019. The value of the order has not been disclosed.
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 shutdowns. 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, said Yi Shuai, Plant Director at power plant of Shanying Huazhong Paper.
Valmet announced in December 2017, that it will supply an OptiConcept M containerboard making line for Shanying International Holdings. This 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 such as paper rejects, pulp rejects and pulp sludge as its fuel totalling to 260 000 tonnes of waste annually. Light fuel oil (LFO) is used only for start-ups. The chlorine and alkaline content in the waste-derived fuel are relatively high, but the company says that by using its CFB technology, the emissions are controlled efficiently.
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.
