Fumes Extraction System is also known as Fume extraction and de-dusting systems are installed to capture the fugitive dust/fumes generated in furnaces or during handling of material before or after various processes. The system consists of suction hoods at various dust/fume generating points, elaborate ductwork, butterfly dampers (both manual and automatic) at appropriate locations, pulsejet bag filter, a centrifugal ID fan and a self-supported stack. Advantages:
No dust cake formation and hence no binding or clogging of bags
No dust deposition in the ducts due to optimally designed air velocity
Minimum power consumption
Completely safe operation
Assured smooth running of the rotary air lock valves and screw conveyors
Minimum downtime which is crucial in case of process equipment
