The Institute of Energy Systems and Technology (EST) at TUDA has large experience in the field of power plant technology, particularly in solid fuel combustion processes and related CO2 capture techniques. Its key expertise lies in modeling and simulation of multiphase flows (e.g. coal-fired boilers, mills, cyclones), modeling of heat exchanger systems (e.g. HRSG), steady-state and dynamic simulation of power plant processes, and experimental investigations of solid fuel combustion processes in laboratory and pilot scale test facilities. A 1 MWth pilot plant consisting of two interconnected CFB reactors has been erected and operated to investigate the carbonate and chemical looping technologies in semi-industrial scale. In recent research projects, the plant was upgraded to be operated as HTW gasifier. Furthermore, it has been extended with syngas cleaning equipment as well as a synthesis test rig. Advanced process models including 1D reactor models have been developed for various processes. A highly sophisticated in-house CFD code using the discrete element method (DEM) for particle/particle interaction has been developed and validated for detailed 3D simulations of dense gas/particle flows. Advanced reaction models for solid fuel conversion, gas phase kinetics, radiative transfer etc. have been implemented into CFD codes for efficient simulations of solid fuel combustion devices.
Sumitomo SHI FW (SFW) is part of an international company Sumitomo Heavy Industries, Ltd. Main products of SFW are steam generators and gasifiers based on fluidized bed technology, cryogenic energy storage, waste heat boilers, multipollutant scrubbers, auxiliary equipment and services to the utilities and industry. SFW is a forerunner of fluidized bed (FB) technologies, delivering the very first circulating fluidized bed (CFB) in 1979, the world’s first supercritical CFB in 2009, the most advanced ultra-supercritical CFBs in 2016, as well as the world’s largest biomass plant in 2012. The company is the world leader in CFB’s and has supplied nearly 520 CFB boilers with a power of up to 550 MWel.
During previous research projects, SFW has developed a design for a 800 MWel CFB (EU CFB800 project). Taking part in the EU “FLEXI BURN CFB” project, SFW has developed the oxy-combustion CFB concept, which allows carbon capture in large scale plants. Furthermore, SFW is currently working in a national project to design hybrid power plants.
Fortum Power and Heat Polska is a Polish subsidiary of Fortum, which is focused on heat production and distribution in five Polish cities. With over 150 power plants in total, including hydro, CHP (combined heat and power), condensing, nuclear, solar and wind, Fortum is the 3rd largest power generator in the Nordic countries and one of the leading heat producers globally. Fortum also provide services for the power generation industry and solutions for consumers to improve the smartness in energy choices.
Within the REBECCA project, Fortum Power and Heat Polska will implement operators knowledge to develop a retrofit concept for utilization of waste-derived fuels, provide data of existing plants and provide access to a commercial CFB boiler for measurements. Furthermore, Fortum Power and Heat Polska will contribute to the evaluation of scientific measurements, simulations, and economic assessments.
Improbed AB was formed in 2015 as a subsidiary to the energy company E.ON. The company has a strong bond to research and has, together with researchers from Chalmers University of Technology (CTH, Sweden), invented and commercialized the technique Oxygen Carrying Aided Combustion (OCAC) for the improvement of existing fluidized bed combustors. The Improbed group has large technical knowledge in fluidized bed applications with many years of research and cooperations with academia as well as daily experience from problem solving in commercial combustion units at E.ON.
RWE Power AG, with headquarters in Essen and Cologne, Germany, is a company of the RWE Group. It is Germany’s largest power producer with about 11,000 employees working in lignite open cast mines, power plants, upgrading facilities and administration.The company contributes with its power production capacity of about 13 GW to the broad RWE energy mix of renewables, lignite, hard coal, nuclear power and gas.
Since the 1980’s RWE Power AG has also developed technologies for co-combustion of residuals like sewage sludge and pulp. RWE Power contributes to the REBECCA project with its practical experience in the field of coal and residual co-combustion, plant operation and flue gas cleaning. Furthermore, RWE Power AG will provide data of existing plants, provide access to a commercial CFB boiler for measurements, as well as contribute to the evaluation of scientific measurements, simulations, and economic assessment.
RINA Group is a global provider of classification, certification, testing, inspection and training services. Two different divisions of RINA Group are involved in the REBECCA project.
RINA Consulting – Centro Sviluppo Materiali S.p.A. (RINA-CSM) is a leading center for applied research that ranks amongst Europe’s top Material Research Centres. Its research activities are mainly related to the modeling and design of materials and products, optimization and development of processes, development of innovative pilot plants and reduction of environmental impact. In the REBECCA project RINA-CSM will contribute in refractory production and testing.
RINA Consulting SPA (RINA-C) provides a wide range of services for power plants covering the whole project life cycle from feasibility and specialized technical studies to conceptual and detailed design, prototyping and testing, project management, site engineering as well as operation and maintenance management. In the REBECCA project, RINA-C will conduct Multi-Level Impact Assessment with a focus on risk assessment, environmental assessment, techno-economic assessment and socio-economic assessment.
CERTH/CPERI is one of the largest research centers in Greece and listed among the TOP-25 of the EU’s Research Centers with the highest participation in H2020 competitive research grants. It is the main Greek organization for the promotion of research and technological development aiming at the improved and integrated exploitation of solid fuels, emphasizing on reducing their environmental footprint through novel CO2 capture and sequestration/utilization technologies. Since 1999, CERTH/CPERI has participated in over 40 EC funded and more than 20 nationally funded projects. CERTH has also built a wide experience with CFD and ASPEN Plus/Dynamic modelling in the CFB field and energy processes in general, by taking part in EU highly linked funded projects (CFB800, SCARLET, Recofuel, FLEX-FLORES, CLARA, REBECCA) and in nationally funded ones (Thermal Exploitation of RDF-TE RDF). Its personnel has long expertise in CFD, process simulation and control, while in 2016 has been accredited the Ansys Academic price Hall of Fame.
