Working principle

How it works

The working process in four steps.

  1. Air goes in

    The FD fan pushes combustion air into the furnace.

  2. Gas is pulled out

    The ID fan draws flue gas through to the stack.

  3. Dampers set the flow

    Dampers and ducts keep draught under control.

  4. Alignment protects the train

    Fan, coupling and motor are aligned to cut vibration.
