    2017-1-10 · Draught fans are a type of industrial process fans and are broadly divided into two types – Forced Draft (FD Fan) and Induced Draft (ID Fan). The primary difference between a forced draft and induced draft is, FD fan forces outside air into the heating system whereas ID fan draws flue gases from the system out into the atmosphere.

  • Dust Problems with Lime Kiln ID Fans – AirStream

    2016-12-13 · An ID fan is required to induce flow through the rotary kiln to facilitate the chemical reaction. This flow is normally heavily laden with dust (5-20gr/ft³), requiring scrubbing/cleaning equipment, which is often downstream of the ID fan. The heavy dust load passing through the ID fan represents a major problem for mills, as the dust sticks to ...
