Functioning of a Bag Filter – apart from it design criteria – grossly depends on its operation and monitoring the functional areas. Many instruments connected to the bag filter are often not put to work in tandem. The collective intelligence of these instruments is often underutilized due to absence of adequate ports of the DCS and lack of specialized knowledge about the bag filters with the programmers of such systems. The limitations of a DCS in providing purging time in steps of milliseconds leads to improper cleaning of bags and waste of precious compressed air. In such applications, IBFC can be effectively used.
