The installation is characterised by its compact structure, which makes it possible to minimise heat losses to the environment and enhance the physical enthalpy of the oxidising agent – flue gases – having a favourable chemical composition with oxygen and water vapour. The test results provided tools for modelling of biomass thermal processing using a non-standard oxidiser in the form of flue gases. The obtained models were used to optimise the indirect co-combustion process to reduce emissions. An overall effect of co-combustion of gas from biomass gasification in the stoker furnace is the substantial reduction in NO emissions by about 22%.}, type={Artykuły / Articles}, title={Numerical modelling of a stoker furnace operated under indirect co-firing of biomass}, URL={http://ochroma.man.poznan.pl/Content/85150/PDF/05-paper-Litka.pdf}, doi={10.1515/cpe-2016-0019}, keywords={CFD modelling, stoker, co-firing, gasification, biomass}, }
