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’ investment in waste-to-energy solution enables high overall efficiency with very effective heat and power generation and supports circular economy. Installation is scheduled to begin in June 2018. Heat and power production will start early 2019.
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.
