The effect of staged combustion in reduction of noxious emissions for agricultural residues using a fluidized bed combustor

Fluidized bed technologies have been shown to play a key role in the area of solid fuel combustion. This study was carried out to investigate the reduction of NOx emission by using staged combustion in a small laboratory scale fluidized bed combustor. The experiments were carried out using palm shell as fuel and silica sand as the bed material. The experimental rig has a maximum capacity of 25 kW. Fluidizing air was supplied through a distributor and secondary air was introduced into the freeboard via an ejector.
