Abstract :
Fly ash may cause serious erosive wear on steel surfaces along the flow path in a circulating fluidized bed (CFB) boiler. In this paper, erosion model and MFIX software were used to evaluate gas-solids flow on erosion rate. The effects of the particle size and density on the erosive wear were compared quantitatively.
