Pulse-jet style bag houses are designed to utilize fabric filter bags with internal support structures commonly referred to as cages. Cages must be strong to withstand the pressure from the filter bag exerted during the particulate collection cycle. Additionally, cages must be selected with the proper structure design to conform to the fabric requirements. Gas steam chemistry will determine whether special metals or special coatings will be required to reduce eliminate corrosion to the cages’ metal surfaces. Cage size, both length and diameter can be crucial to the success or failure of the filter bag.
