Abstract
The present disclosure relates to a fabric filter system, which may be used for removing particulate matter from a gas, such as a combustion process gas. The filter system includes a fabric filter () which is placed in a filter compartment. From the filter, gas flows via a filter plenary space () to an outlet duct (), where the gas exits. A flow control device controls the amount of air exiting through the outlet duct. The flow control device comprises a louver-type damper (). This provides reliable and efficient control of the gas flow. A collar (), connecting the plenary space () with the outlet duct (), improves the gas flow into the duct.
