Erosion is a generic problem in fluidized bed boilers. This paper identifies the erosion-prone areas in circulating and bubbling bed fluidized bed boilers, and the currently used methods for erosion protection. Recent experience with thermal spray coatings in these areas is discussed as are the complications presented by burning fuels that introduce corrosion to the already erosive environment. The paper concludes with some comments on future considerations for the protection of fluidized bed pressure parts from general wastage due to erosion and corrosion.
