Abstract

The emissions from FBC are very dependent on a number of operating conditions (temperature, staged air, excess air, fuel feed rate, etc.) and fuel properties. This paper described the experimental results taken in a staged air fluidized bed combustion laboratory scaled, using palm shell as fuel and silica sand as the inert bed material. The silica sand was used for ensuring sustainable fuel ignition and combustion in FBC. The variation of fuel feeding rate was taken in these experiments. Gaseous emissions of CO and CO2 concentrations and temperature along the combustor height as well as in flue gas were measured in the experimental tests. The experimental results showed that the axial temperature profiles decrease successively related along the FBC height. The CO and CO2 emission obtained results lower for staged air condition than for un-staged air condition. The palm shell gives significant contribution for reduction of pollution from combustion process.
