Valmet to Supply Cheng Loong's Houli Paper Mill in Taiwan with CFB Boiler

Valmet CFB boiler The new boiler is a significant investment in decarbonization of the mill as it will enable the reduction of coal usage and replaces an older less efficient waste boiler.

Nov. 17, 2025 - Valmet will deliver a CFB (circulating fluidized bed) 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 value of the order will not be disclosed.

The new boiler is a significant investment in decarbonization of the mill as it 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," said Charles Chang, President, Cheng Loong Corporation. "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," Chang added.

According to Valmet, 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.

Niina Ollikka, Vice President, Boilers and Gasifier Solutions, Valmet, explained, "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."

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.

The new power plant is a significant investment in decarbonization and modernization of the CLC Houli mill's energy production.
