Fortum and Metso to cooperate on oxyfuel combustion
Fortum and Metso have launched a joint project to explore the potential of oxyfuel combustion technology and carbon capture in power and heat generation, with assistance from Tekes, the Finnish Funding Agency for Technology and Innovation.
The project will focus on how oxyfuel combustion technology can be implemented in an industrial-sized power plant based on circulating fluidized bed (CFB) combustion, which is ideal for firing a wide selection of fuels, either alone or in flexible combinations.
Fuel is combusted with pure oxygen diluted with recirculated flue gas instead of air in oxyfuel combustion. Following cleaning, flue gas consists mainly of water vapour and CO2, which can then be pressurised, transported, and stored.
Comprehensive testing will be carried out during 2010 and will address the needs of both modernisation projects and new power plants. Metso’s 4-MW test plant in Tampere will be modified for oxyfuel combustion as part of the project.
"Fortum's long term goal is to be a CO2-free energy company and we have been working towards this goal systematically for several years. This project is an important part of Fortum’s long-term R&D activities because the technology can be applied not only in coal-fired energy production but also in power plants using biomass," says Marja Englund, manager of the project at Fortum.
