Corrosion behaviour of boiler tube materials during combustion of fuels containing Zn and Pb
(Åbo Akademi University, Process Chemistry Centre, 2012-06-16)
Many power plants burning challenging fuels such as waste-derived fuels experience failures
of the superheaters and/or increased waterwall corrosion due to aggressive fuel components
already at low temperatures. To ...
Characterisation of waste for combustion : with special reference to the role of zinc
(Åbo Akademi University, Process Chemistry Centre, 2013-12-11)
Waste combustion has gone from being a volume reducing discarding-method to an energy recovery process for unwanted material that cannot be reused or recycled. Different fractions of waste are used as fuel today, such as; ...
Modeling of fireside deposit formation in two industrial furnaces
(Åbo Akademi University, Process Chemistry Centre, 2013-12-05)
Fireside deposits can be found in many types of utility and industrial furnaces. The deposits in furnaces are problematic because they can reduce heat transfer, block gas paths and cause corrosion. To tackle these problems, ...
The role of potassium in the corrosion of superheater materials in boilers firing biomass
(Åbo Akademi University, Process Chemistry Centre, 2013-12-13)
Inhibition of global warming has become one of the major goals for the coming decades. A key strategy is to replace fossil fuels with more sustainable fuels, which has generated growing interest in the use of waste-derived ...
Chemical changes in biomass during torrefaction
(Åbo Akademi University, Johan Gadolin Process Chemistry Centre, 2016-01-22)
Torrefaction is moderate thermal treatment (~200-300 °C) of biomass in an inert atmosphere. The torrefied fuel offers advantages to traditional biomass, such as higher heating value, reduced hydrophilic nature, increased ...
The feasibility of torrefaction for the co-firing of wood in pulverised-fuel boilers
(Åbo Akademi University, Johan Gadolin Process Chemistry Centre, 2015-12-11)
Torrefaction is the partial pyrolysis of wood characterised by thermal degradation of predominantly hemicellulose under inert atmosphere. Torrefaction can be likened to coffee roasting but with wood in place of beans. This ...
Combustion properties of biomass residues rich in phosphorus
(Åbo Akademi University, Process Chemistry Centre, 2012-04-04)
The currently-used sources of biomass are limited so new ones are required in order to
meet the European Union target and to satisfy the constantly-increasing demand for
energy. This is why energy recovery from residues ...
Enzyme electrode configurations : for application in biofuel cells
(Åbo Akademi University, Process Chemistry Centre, 2012-02-17)
Understanding the in vitro dissolution rate of glasses with respect to future clinical applications
(Åbo Akademi University, Process Chemistry Centre, 2012-12-05)
Glass is a unique material with a long history. Several glass products are used daily in our everyday life, often unnoticed. Glass can be found not only in obvious applications such as tableware, windows, and light bulbs, ...
Fate of fuel-bound nitrogen and sulfur in biomass-fired Industrial boilers
(Åbo Akademi University, Process Chemistry Centre, 2014-02-14)
