The carbon monoxides reduction and temperature profile of palm shell and palm fiber combustion in fluidized bed combustor

The emission from FBC is very dependent on a number of operating conditions (temperature, staged air, fuel feed rate, excess air, etc.) and fuel properties.

Description
Summary:The emission from FBC is very dependent on a number of operating conditions (temperature, staged air, fuel feed rate, excess air, etc.) and fuel properties. This paper describes the experimental results taken in a staged air fluidized bed combustion laboratory scale, using palm fiber and palm shell as fuels and silica sand as the inert bed material. In this experiment, a variation of excess air and secondary air were measured. Measurement of gas emissions of CO and CO2 concentrations, combustion efficiency and temperature, were taken along the combustor height as well as in flue gas. The experimental results show that the axial temperature profiles decrease successively along the FBC height. The CO emission obtained was lower for the staged- air condition than for the un-staged-air condition. The combustion efficiencies show satisfactory values.
