About Us

Advancing Our Technologies

Higher Thermal Efficiency Each Year


Next to our people, our technology is vital to our business so we strongly invest in protecting and advancing our technology. To ensure the highest level of attention, our technology steering committee (TSC) reports directly to our CEO of SFW. The TSC steers and oversees our intellectual property, research and development (R&D), Innovation and technology strategy and is an important part of our technology management system.

Our R&D resources and capabilities are among the best in the industry, built on a network of our own R&D department and labs as well as partnerships with universities; government R&D agencies, like Finnish VTT and Business Finland; and industry R&D groups, like Electric Power Research Institute (EPRI) and the High Temperature Corrosion Centre (HTC). We also work in close collaboration with other technology suppliers and end customers towards the definition and demonstration of novel solutions. Lastly, we participate in networks such as CLIC and ETIP-SNET for the creation of the strategies and the roadmaps that support the regulatory and legislation process in EU.

Materials Laboratory

Our Materials Laboratory is a highly advanced facility located in Varkaus, Finland. Our equipment allows for detailed analyses of metallurgical samples, refractory materials and other process materials such as fuels and ash. We employ some of the top experts in their respective disciplines and provide professional evaluations of analytical results.


  • Advanced materials research
  • Development of advanced fabrication techniques
  • Failure and root cause metallurgical analysis
  • Corrosion evaluations
  • Macro and micro-hardness testing
  • Optical microscopy
  • Scanning electron microscopy (SEM) evaluations
  • Chemical Analysis e.g. EDS and XRF
  • Hot rigs for fluidization characterization

Additional laboratory testing capabilities are secured in our Cold Lab located in Sosnowiec, Poland, including:

  • Cold models of boilers, boiler components, and AQCS
  • Erosion testing rig
  • Fuel flowability rig

R&D Department

Our R&D Department is a world-class research organization, leading in the development of fluidized bed technologies, while expanding expertise in new areas of decarbonization, digitalization and energy storage. The department is represented at several SFW locations and headquartered in Varkaus, Finland. Our R&D department is expert in all key disciplines relevant to fluidized bed products and is increasingly knowledgeable in growing areas, including:

  • Development of proprietary models for the design of boilers, gasifiers, and scrubbers, including dimensioning and prediction of key performance parameters
  • Development of risk management tools for agglomeration, fouling, erosion, and corrosion
  • Modeling and development of training tools for boiler dynamics and control
  • Modeling of single and multiphase fluid processes utilizing commercial and own software
  • Field measurements at plants using commercial and proprietary instrumentation and procedures
  • Field testing of boiler materials during plant operation
  • Physical and chemical laboratory characterization of process materials such as fuels, additives, and ash
  • Design, maintenance, and utilization of databases from operating customer sites and pilot tests
  • Development of integrated solutions towards greener and more secure energy supply
  • Development of novel technologies and tools for the decarbonization and digitalization of the energy and industrial sector
  • Development of concepts and techniques for the optimization of energy storage solutions

The department has an extensive network of key partners and subcontractors to ensure excellence in all modeling, analytical and testing work.

Targets of the R&D Department include the continuous improvement of competitiveness for core products (short-term R&D), the rise to marketability of new products and solutions via piloting and commercial demonstration (mid-term R&D), and the early screening of future technologies with market potential (long-term R&D). The R&D Department also supply IP expert support to ensure the best protection of innovative ideas for all the product lines of SHI FW and novel prospect areas.

Existing CFB pilot test facility

CFB Pilot Test Facility

Our CFB pilot test facility located at the Technology Research Center in Niihama, Ehime, Japan is designed to test fuels in environments very close to commercial equipment conditions. The center includes a fluidized bed furnace, deposit test equipment, high temperature erosion-corrosion test equipment, shear strength tester of ash and a large 1 MWth CFB pilot test rigs. The center is extensively used to test all types of coals, sludges, biomasses, refused plastic fuels, tires and other fuels to help us optimize our commercial CFB designs.
