Evaluation Methods of Wear Properties of Bag Filter using an Optical Fiber and Magnetic Particles

In these years, the bag-filter in a dust collector of the waste incinerator is used widely to remove the toxic substance, for example toxic gas, dioxins and heavy metals included in the ash dust by passing through the filter cloth. In order to prevent the destroy of filter, it is necessary to establish the evaluation method of wear for bag-filter. In this study, evaluation methods of wear for bag-filter are proposed by using ferromagnetic particles and optical fiber. Using these evaluation methods, wear mechanism for bag-filter was discussed.
