Life extension of erosion affected components through the calculation of deformation under erosion stress

摘要

In fluidized beds, damage occurs in the form of erosive material destruction by virtue of the high-solid material thicknesses and speeds. The paper introduces a model, by means of which the erosive destruction in relation to the materialproperties and flow parameters can be calculated. With these calculations, it has been possible to achieve a substantial reduction in deterioration in some heavily erosion affected areas of certain circulating fluidized bed combustion plants.
