For a long time, the selection of fuels for biomass combustion, in terms of avoiding problems such as slagging and fouling of the reactors, often was carried out based on trial and error. About a decade into the 21st century, a group of Sweden-based researchers with long-standing experience in high-temperature conversion of woody feedstock to heat and power started to mull over a more systematic approach to assessing the reactions in thermal conversion of the chief trouble-making content of the biomass: the inorganic compounds forming the ash.
In 2012, the scientist, brought together under the umbrella of Bio4Energy, published an article on Ash Transformation Chemistry during Combustion of Biomass in the interdisciplinary scientific journal Energy & Fuels by the American Chemical Society (ASC). The article describes a conceptual model by which any type of biomass—whether originating from wood, woody or agricultural residue or other types of combustible waste—may be characterised, and thus understood, in terms of the basic chemical reactions that take place during thermal conversion of biomass into heat, power, fuels and chemicals.
After having been amply cited by other researchers around the world, this spring, the article by Bio4Energy scientists received the 2017 Energy & Fuels Joint Award for Excellence in Publication.
