Abstract

Bag filters composed of fibrous components are widely used to clean exhaust gas. It is reported that filter damage during dust collection involves erosion wear caused by particle collision. Thus, it is necessary to determine the life of bag filters in a hot environment and to clarify the erosion mechanism of fibrous materials. Experiments and evaluation methods were developed to investigate the erosion of fiber at high temperatures. The experiments involved reproducing the erosion of fibrous materials in various temperatures. Analysis of the relationship between the erosion damage rate of a specimen and the total kinetic energy of particles before colliding indicates the erosion resistance of fibrous materials at various temperatures. Using the suggested damage energy curve, we can evaluate the erosion wear characteristics of fiber under different experimental conditions.
