See an example of how fabric expansion joints are being used with ducting. The figure below represents a typical balanced draft system with a “cold” precipitator. The black components represent the locations of fabric expansion joints throughout the system.

**The examples above are representative and should not be used for design. The user should obtain actual values for the particular system being considered

The main sections of the ducting are as follows:

  • FD Fan to Air Preheater
  • Air Preheater to Boiler
  • Air Preheater to Pulverizer
  • Air Preheater to Inlet from Boiler
  • Air Preheater to Precipitator or Bag house
  • Precipitator or Bag house to ID Fan
  • ID Fan to Scrubber
  • Scrubber to Stack
