Valmet to supply new waste-to-energy boiler to Cheng Loong Corporation in Taiwan

Valmet will deliver a CFB boiler, flue gas treatment and automation system for Cheng Loong Corporation’s (CLC) Houli paper mill in Taiwan. The boiler will use various waste and biomass streams as fuel to produce electricity and heat for the mill. The new boiler is a significant investment in decarbonization of the mill as the new boiler will enable the reduction of coal usage and replaces an older less efficient waste boiler. CLC has estimated that this new boiler will reduce the mill’s annual CO2 emissions by 48,000 tonnes.

The boiler is designed for high fuel flexibility to use both industrial and municipal waste streams (RDF, SRF and TDF) as well as biomass as fuel. The Valmet CFB Boiler utilizes circulating fluidized bed (CFB) technology, which, when operated with high steam parameters, enables significantly higher electricity production from waste fuels compared to traditional waste combustion technologies.

Valmet’s delivery scope includes a Valmet CFB Boiler and flue gas treatment. The boiler will have a fuel capacity of 107 MW and is optimized for overall thermal efficiency. Low emissions are achieved with the flue gas treatment system including pre-separator, additive injection, dry system, bag house filters and SCR.

The automation system Valmet DNA represents the latest distributed control system with industry-leading user experience and cybersecurity.
