Industrial Centrifugal Fans as ID and FD Fans in Core Manufacturing Sector

By | April 27, 2022

Most people mistakenly think that industrial centrifugal fans are the same as the exhaust fans that they see in their daily lives. They are unaware of the fact that the role of a typical centrifugal fan is way bigger than that of the general exhaust fans.

The induced draft (ID) and forced draft (FD) fans can be called as being the most important ones among the varied kinds of centrifugal fans. They are indispensable elements of the core manufacturing sector. It’s just not possible to carry out the day-to-day operations in a manufacturing plant, without the presence of these fans.

Installing these fans, also known as blowers, is much more necessary in industries such as cement, thermal power, and steel. At this juncture, it will only be appropriate to succinctly speak of the role of ID and FD fans in the manufacturing sector.

FD fans

Induced draft fans
These are some important points related to the usage of ID fans in manufacturing units:

  • The ID fans collect the entire noxious by-products of the combustion process and expel them into the outside environment, through the chimney.
  • For the above purpose, the induced draft blowers lead to a generation of negative pressure within the system.
  • The fans are fixed close to the boiler systems outlet to ensure that toxic fumes and gasses get eliminated.

Forced draft fans
Let us now have a look at some salient aspects of how forced draft fans are used in the core manufacturing sector.

  • The basic functioning of an FD fan is completely different from an ID blower. A forced draft fan, by generating a positive pressure, takes in the air from the external environment and thrusts it into the system. To make certain that there is no hindrance in achieving this objective, the FD fans are installed near the inlet of the boiler.
  • The air pushed inside increases the speed of the combustion process, which eventually gets completed appropriately.
  • The forced draft blowers, which are usually curved in the backside direction, are tidier when compared with the ID variants.

ID fans and FD fans- benefits
Despite the aforesaid differences, there is one thing that is common between the two types of blowers. Both ID and FD fans provide several benefits to manufacturing units. Here, it will be worthwhile to have a glance at a few of the corresponding points.

  • The quantity of power consumed by both a forced draft and an induced draft fan is fairly low. As a result of that, the business is enabled to save plenty of money that would have otherwise gone towards the payment of electricity bills.
  • The life of the impeller in ID and FD fans is much longer than that seen in other kinds of blowers. And, when the impellers come with long life, there is a drastic reduction in the maintenance costs, over some time.
  • Likewise, the bearings of these blowers last for a very long duration, as well. This again helps the factory in markedly cutting down costs.
  • The amount of noise emitted by the blowers is negligible and thus there is reduced sound pollution within the plant. The employees are then able to concentrate more on their work; the manufacturing unit’s productivity gets enhanced, in the long run.
