“…Disparities can occur not only between two zones of the same bag (e.g. patchy cleaning [23,[35][36][37][38][39]), but also between two separate bags or between several different groups of bags. Some authors also observed that the dust cake properties (packing density, breaking strength, cohesion or adhesion forces) mainly depend on the filtration velocity [22,27,[40][41][42].…”

“…4a) confirms the duration of this transition period. The concavity is logical because it reflects an analogy with a patchy cleaning (such behavior has been observed by other authors [39,[49][50][51][52][53]). The parallel with a patchy cleaning can be explained as follow: areas, which are still clogged after a patchy cleaning, correspond to the first cleaned bags (because both have the higher airflow resistances); and areas, in which dust cake has been detached in a patchy cleaning, are similar to the last cleaned bags (because both have the smallest airflow resistances).…”

Measurement and Simulation of Axial Velocity in a Filter Bag

The axial velocity in two different tests with pulse‐jet bag filters made of needle felts on a pilot‐scale test facility separating limestone dust from air under ambient conditions is measured and simulated at different cake area loads. Results reveal that the axial velocity profiles are not truly linear along the whole length of the bag. A nonuniform gas flow prevails when the bags are differently dust‐loaded. The same behaviors are observed even at the end of filtration cycles at different upper pressure drop limits. At the higher upper limit, the nonuniformity is stronger. Radial velocity profiles are nearly symmetric along the length of the bag.

Evaluation of the Efficiency of Filtration Processes Using Precoat Materials

The highly efficient filtration of ultrafine dust emitted by biomass combustion processes with a baghouse filter has been successfully tested in the last years. To protect the filter material from the very small and sticky fine dust particles and to guarantee very high total collection efficiencies (> 99 %) in a long‐term stable process, the use of a precoat is necessary. Tests done in a laboratory and a real‐application plant show that the reuse of precoat materials can lead to significant savings. Considering the influences of different combustion processes, the associated precoat efficiencies could be calculated. With these characteristic ratios, it is possible to evaluate different process settings. Hence, the amount and the cost of the needed precoat could be reduced significantly.
