Broken filter bag detection at a dust collection duct in an off-gas system

Baghouse filters are equipped with several hundreds of filter bags. Even if only one filter fails, the emission limit for dust can be exceeded. Therefore, it is important to identify and replace the defective bag as quickly as possible. However, due to the size of the baghouse, this can be a challenging task. Even if the dust leak is small, there is no indication of the emission infraction on the clean gas side. Sensitive dust emission monitoring equipment can be used to link the dust emission peaks with those bags in the cleaning cycle and help locate the broken bag for replacement.
