5. FABRIC FILTER
Fabric filter is a cylindrical filter bag
of fabric.
Several identical bags can be placed
in a bag house.
Removal efficiency = 99.9%
Particle size range = 0.01 to
100(micro meter).

6. WORKING PRINCIPLE OF FABRIC FILTER

7. TYPES OF FABRIC FILTER
Reverse gas fabric filter (RGFF)
Pulse jet fabric filter (PJFF)
Bag shaker house

8. Reverse gas fabric filter (RGFF)
Common diameter of bags 8-12inches
Length of bags'= 22,30 or 35 feet
Reverse gas fans and ducts recycle part of
the clean flue gas from the exit manifold
back through the compartment during the
cleaning cycle.

9. How it work

10. Pulse jet fabric filter (PJFF)
Common diameter of bags 5-6inches.
Pressure of compressed air = 100psi.
Pulse duration = 0.1sec.
Cleaning = one row of bag at a time then
other bag.

12. Bag shaker house
Shaking method can be used to clean
the bags with mechanical shaking.
Duration of shaking = (30sec to a few
minutes)
Common diameter of bags = 5,8,12 (inches)
