Finland-headed forest industry and energy technology major Valmet Oyj has announced that it will deliver a circulating fluidised bed (CFB) boiler, flue gas treatment and automation system for Cheng Loong Corporation’s (CLC) Houli paper mill in Taiwan.
Established in 1959 and headquartered in New Taipei City, Taiwan, Cheng Loong Corporation (CLC) specializes in papermaking and paper converting, exporting its products worldwide.
The company has five paper mills and 18 box plants in Taiwan, China, and Vietnam with a total annual capacity of over 2.50 million tonnes of paper products (paper and paperboard) and more than 1.9 billion m2 of paper containers.
The CFB 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 the decarbonization of Houli Mill, as it will enable the reduction of coal usage and replace an older, less efficient waste boiler.
CLC has estimated that this new boiler will reduce Houli Mill’s annual carbon dioxide (CO2) emissions by 48,000 tonnes.
Together with Valmet, we will 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 emissions and increase the proportion of non-fossil fuels in the 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, said Charles Chang, President, Cheng Loong Corporation.
High fuel flexibility and thermal efficiency
Valmet’s delivery scope, the value of which has not been disclosed, includes a Valmet CFB Boiler and flue gas treatment, designed for high fuel flexibility to use both industrial and municipal waste streams such as RDF, SRF, and TDF, as well as biomass.
The boiler will have a fuel capacity of 107 MW and is optimized for overall thermal efficiency.
The 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.
Low emissions are achieved with the flue gas treatment system, including pre-separator, additive injection, dry system, bag house filters, and SCR.
The Valmet DNA automation system represents the latest distributed control system, offering an industry-leading user experience and robust cybersecurity.
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, said Niina Ollikka, VP, Boilers and Gasifier Solutions, Valmet.
