Table 4: Strengths and Weaknesses of Fluidised Bed Incinerator
Strengths Weaknesses
● Good temperature distribution
● No hot spot
● Good gas and solid mixing
● Low tar content in product gas
● High carbon conversion efficiency
● Tolerate wide variations of fuel quality
● High energy requirements for blower/
compressor for fluidising air
● High dust and particulate in flue gas
● Possibility of de-fluidisation due to
agglomeration of solid in the bubbling bed
● Erosion of internals resulting from high solid
velocities in the circulating bed
● Added complexity in designing and operating
the recirculating loop for circulating bed
