Abstract
A fabric filter bag (50) and cage (10) system for use in a bag house (66) for industrial process gas stream particulate removal. The bag house (66) includes an inlet (68) for process gas flow into an interior space (65) thereof, at least one fabric filter bag (50) and cage (10) system within the interior space (65) for filtering the process gas as it flows therethrough, and an outlet (70) for flow of cleaned process gas out of the interior space (65) of the system. The subject fabric filter bag (50) and cage (10) system provides about an additional 14% filter material per bag as compared to like sized round filter bags, thereby effectively reducing the size of bag house (66) required to achieve a particular air to cloth (A/C) ratio. Reducing the size of the bag house (66) required to achieve a particular A/C ratio significantly reduces capital costs typically associated therewith.
