ABSTRACT: Fluidized bed combustion behavior of coal and biomass is of practical
interest due to its significant involvement in heating systems and power plant
operations. This combustion behavior has been studied by many experimental
techniques along with different kinetic models. In this study, SO2 emissions have been studied out in a pilot scale test facility of Circulating
Fluidized Bed combustor (70 KW) under fast fluidized bed conditions burning
coal with Pakistani wheat straw. One dimensional Mathematical model is being
developed to predict the SO2 emissions under different operating
conditions like bed temperature, Ca/S molar ratio, solids circulation rate,
excess air ratio and secondary to primary air ratio. These parameters are
varied to validate the model and encouraging correlation is found between the
experimental values and model predictions.
