Metso and Fortum's joint development work on oxyfuel combustion technology makes headway
(Thomson Reuters ONE) -
Project aims to considerably reduce CO(2) emissions
Metso Corporation's press release on May 16, 2011 at 10:00 a.m. local time
In a joint R&D project, Metso and Fortum have developed oxyfuel combustion
technology that aims to reduce the CO2 emissions of power plants. In 2010,
Metso's 4-MW test plant in Tampere, Finland, was modified for oxyfuel
combustion, resulting in the biggest known oxyfuel combustion process based on
circulating fluidized bed technology in the world. Circulating fluidized bed
boilers can be operated with a wide range of fuel types, such as coal, biomass
and a mixture of fuels. The pilot has come to an end and the results of the
project will be evaluated during 2011.
The joint project between Metso and Fortum involves research into switching over
from air combustion to oxygen combustion. In oxyfuel combustion, the flue gas
consists of almost clean water vapor and CO2, which can be captured. Adding a
carbon dioxide recovery system to a biomass-fired power plant creates a carbon
sink that abates climate change.
During the project, an international research cooperation network was
established. Without such a network, it would be impossible to realize a project
of this kind, which require extensive know-how. In addition to Metso and Fortum,
the project is partly funded by Tekes, the Finnish Funding Agency for Technology
and Innovation.
"We have carried out a comprehensive series of tests ranging from laboratory
measurements to continuous pilot-scale tests. In the pilot-scale testing, we
focused on developing both the actual boiler process and safe operation of the
boiler plant during oxyfuel combustion. Modifying Metso's 4-MW test plant for
oxyfuel combustion has been challenging and we are pleased with what we have
achieved. With circulating fluidized bed technology, coal and biomass can be co-
fired, thereby turning the power plant into a carbon sink," explains Jussi
Mäntyniemi, General Manager, Technology at Metso's Power business line.
"Fortum has been very pleased with how the project has proceeded. By altering
Metso's test equipment for oxyfuel combustion, we have received a lot of new
information in terms of the future opportunities that the technology offers. The
tests provide both empirical data and new information concerning the operation
of the plant," says Marja Englund, manager of the project at Fortum.
In oxyfuel combustion, process fuel is combusted with a mixture of pure oxygen
and recirculated flue gas instead of air. After cleaning, the flue gas consists
of water vapor and CO2. Oxyfuel combustion can be used in circulating fluidized
bed boilers that can be operated with a wide range of fuel types, such as coal,
biomass and a mixture of fuels.
Metso is a forerunner in developing innovations and apart from contributing to
research in oxyfuel combustion, Metso is also involved in developing new
technologies for torrefaction, biogasification, pyrolysis and LignoBoost that
are important energy solutions for the future.
Metso is a global supplier of sustainable technology and services for mining,
construction, power generation, automation, recycling and the pulp and paper
industries. We have about 28,500 employees in more than 50 countries.
