This study used computational particle-fluid dynamic (CPFD) analysis techniques to analyse the fluidisation and reaction characteristics in a 0.1 MWth oxy-fuel circulating fluidised bed (oxy-CFB) combustor. An oxy-CFB 3-dimensional model incorporated with various reaction kinetic models as stated in previous studies is used to predict the flue gas compositions. The gas and solid profiles in the oxy-CFB combustor shows a typical CFB structure consisted of dense and lean phase in the combustion chamber. Furthermore, the formation of CaSO4 particles is evidence of a direct desulfurisation reaction between CaCO3 and SO2 in the oxy-CFB combustor. As a result, a continuous direct desulfurisation of CaCO3 occurred in the reactor, which is expected to achieve maximum conversion in the long term.
