The potential of fluidized bed combustion to utilize very poor fuel is shown in the two extremes of coals being burnt, from good graded/stoker coal to colliery waste. It is emphasized that very careful engineering must be carried out to overcome difficulties associated particularly with handling these fuels up to the point of their injection into the bed. Boiler efficiencies, varying from low seventies for poor fuel to well over 80% for the high grades of fuels show the economic advantage of using this technology. The fluidized bed combustion boiler has commercially demonstrated its capability to burn a wide range of fuels efficiently while meeting all environmental standards.
