- Abstract
- In order to study the wear of bag-filter by ash dust, sintered magnetite (Fe(3)O(4)) compact was used for counter material for sliding wear test. The precise amount of magnetite particles embedded into bag-filter was determined by a vibration sample magnetometer (VSM) measurement. It is found that net amount of wear of the bag-filter could be precisely determined by the magnetic measurement. It is also found that the net amount of sliding wear of the bag-filter increases with increasing the wear distance, sliding speed and applied load. To discuss the validity of proposed method,shot peening test with deoxidized iron particles was also carried out for bag-filter sample. The data obtained by the shot peening testis consistent with that obtained by the sliding wear test. The proposed method is, thus, very useful to evaluate the net amount of wear of bag-filter by the fly ash. (C) 2008 Elsevier B.V. All rights reserved.
