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 mill’s annual CO2 emissions by 48,000 tonnes.
“Together with Valmet, we jointly build the largest biomass energy cogeneration system in Taiwan at CLC’s flagship Houli mill, which will serve as a model for our operations. With this investment the Houli mill will be able to significantly reduce carbon emission and increase the proportion of non-fossil fuels in Houli mill to more than 30 percent. Additionally, all solid waste from the Houli mill will be efficiently handled. We chose Valmet as our partner for its proven expertise in biomass and waste-to-energy technologies, reliable project execution, and strong local support in Taiwan. We share the same commitment to sustainability, energy efficiency and reduction of carbon emissions,” says Charles Chang, President, Cheng Loong Corporation.
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.
“This order is a great example of how we can combine our core boiler and emission control technologies and automation to deliver high performance and flexibility. Thanks to the extensive experience we've gained through our own R&D center and previous projects, we’re well equipped to handle challenging fuels — including a wide variety of waste streams,” says Niina Ollikka, Vice President, Boilers and Gasifier Solutions, Valmet.
