| Summary: | The emissions from FBC (Fluidized Bed Combustion) are dependent on temperature, staged air, excess air, fuel feed rate and fuel properties. In this paper therefore, an accurate report of the experimental results taken in a staged air fluidized bed combustion scale is given. It is important to note that during the experiment, palm shell was used as fuel and silica sand as inert material. The silica sand was used to ensure sustainable combustion in FBC while changing of fuel feeding rate was carried out successfully by modifying the rotation of Miki pulley with time. Furthermore, the amount of partial changes in excess and secondary air were obtained through measurement. The gaseous emissions of CO and CO2 concentrations were measured using TOCSIN 320 gas analyzer while the temperatures along the combustor height and the flue gas were obtained using the K-type thermocouples. According to the results obtained, 0% and 60%EA at 40%SA is the most favorable condition when trying to reduce CO emission. However, increasing of air staging level will reduce the CO2 concentration at 60%EA. |
