13. Investigation of the combustion behavior in a fluidized reactor with oxygen carriers as bed material
University essay from KTH/Energi- och ugnsteknikAbstract : The behavior of using oxygen carriers as bed material in a fluidized bed combustion was investigated in this work when methane, air and carbon monoxide, air are used as fluidizing gases. More specifically, conversion rate, unsteadiness and gas composition was investigated and it was found that the conversion rate of carbon monoxide and methane are higher when oxygen carriers are used as bed material compared to silica sand and that the highest conversion rate was for oxygen carriers with high oxygen transport capacity and high reactivity towards the gaseous fuel.
