A range of measuring and flow visualisation techniques have been developed to study wear in laboratory units and commercial boilers. The major factors influencing tube wear have been identified and design solutions developed. Wall wear has been successfully eliminated by the installation of metal shelving or refractory coating. Stainless steels have been shown to provide no improvement in wear resistance, compared with mild steel, under the conditions employed in UK industrial boilers. However, a number of surface treatments gave encouraging performance and are worthy of further investigation. It is concluded that, provided boiler makers and their customers implement the guidelines outlined, wear within the bed of FBC boilers and boiler smoke passes can be eliminated or reduced to an acceptable level.
