Valmet to add biomass co-firing to coal-fired circulating fluidized bed boiler in Indonesia

Valmet will supply a partial bioconversion for PT. Cikarang Listrindo Tbk's coal-fired circulating fluidized bed (CFB) boiler in Babelan, Indonesia. The investment reflects Cikarang Listrindo's initiative for greener energy production and environmentally friendlier operation by reducing reliance on fossil fuels and cutting CO2 emissions. Modification works are scheduled for the Q1 2025.

"This new step will allow up to 25% of the company's total coal consumption to be replaced by biofuel and is in line with the company's commitment to reduce greenhouse gas emissions by 20% by 2030, supporting the Indonesia's government's commitment to the energy sector," says Sami Sivola, Head of the Environmental Sustainability Team, PT. Cikarang Listrindo.

The rebuild of the coal fired boiler unit 2 is part of Cikarang Listrindo's development program to increase the use of more sustainable fuels in combustion.

PT. Cikarang Listrindo is also utilizing renewable fuels in its steam generation process by rebuilding the existing CFB boiler in unit 2. Since the rebuild, up to 30 percent of the energy produced with coal in this boiler can be replaced by woodchips and other suitable biofuels.

Valmet's delivery scope includes the engineering, supply and construction of a new biomass fuel feeding system and the addition of a flue gas recirculation system for the CFB boiler unit 2. The furnace bottom will also be modified to improve coarse material removal from the fluidized bed.

Cikarang Listrindo is today one of the largest-capacity electricity companies in Indonesia.

Valmet is a leading global developer and supplier of process technologies, automation and services for the pulp, paper and energy industries.
