The reasonable design and operation of the dust collector can extend the service life of the dust removal bag. The design of the dust removal bag will interact with the collected smoke and dust, meanwhile dust removal bag can have a significant impact on the pressure drop and dust concentration of the power plant due to small differences in design. The design of the dust collector operation process can also have a serious impact on the operation effect of the dust collector. Frequent dust cleaning often leads to high smoke and dust emission concentrations, and significantly shortens the lifespan of the dust collector bag. Therefore, it is necessary to optimize the relationship between ash cleaning frequency and pressure drop. The dust collector used in power plants is usually divided into multiple unit rooms, so that the dust collector bag can be closed, repaired, or replaced online. The dust collector bag is easily damaged when facing high-speed airflow and often occurs on newly installed dust collectors.

Therefore, it is necessary to carefully control the start-up of newly installed dust removal bags. The resistance of the dust removal bag after dust removal comes from two aspects: the particles in the fiber of the dust removal bag and the ash layer attached to the bag that has not been removed during the dust removal process. The cleaning effect is related to the cleaning energy entering the bag and the strength of the ash layer attached to the bag. Some deviations during operation may lead to an increase in the strength of the ash layer. Low temperature operation can lead to acid condensation on the ash layer, leakage of boiler pipelines can cause smoke and dust to carry water, causing the ash layer to harden, and improper operation during fuel consumption may cause smoke and dust to carry oil. Therefore, the reasonable design and operation of dust collectors can extend the service life of dust removal bags. We, the majority of users, should pay special attention to this in the design and use process.
