2. ID and FD Fans are an essential component in the manufacturing process in the core
sector of industry. This ID/FD process fan equipment can be called the backbone of
the manufacturing process in thermal power generation, cement, steel
manufacturing, fertilizers among others core industries. The draught fan is British
English while its equivalent word in US English is the draft fan.

3. For an average urban person and even from a rural background it is not on their
horizon to imagine the process fans used in core manufacturing plants. The kind of
ID/FD fans used in such manufacturing plants is something most people are unaware
of – this is the reason, they tend to associate industrial process fans with ventilation
systems which are more ubiquitous and found in residential settings in the urban
environment. These manufacturing plants in a variety of industries in the core sector
like thermal power generation, cement, steel manufacturing, copper manufacturing
are located in far-off places as a result a normal person has little exposure to the
size.

4. In the case of steel manufacturing, to create steel the iron ore needs to be heated at
a high temperature which needs large quantities of pulverized coal and air mixture
to be fed into the furnace. This conveying or feeding of the combustible pulverized
coal and air mixture into the furnace is done by forced draught fans. In addition to
forced draught fans, induced draught fans could be used in combination to balance
the system. Similarly forced draught fans and induced draught fans are also used in
other metal manufacturing plants like aluminum and copper.
These industries are not built for small scale but for economies of scale to ensure
the manufacturing can happen at the cheapest possible cost. When such large
manufacturing plants are setup up there are many activities that need to be
automated to ensure high volume output in the production process.

5. Take for example the feeding of coal into the furnace to create steam in the thermal
power plant. For the sheer scale of the combustion, and the continuous support in
providing pulverized coal to the furnace – there is no substitute for using an induced
draught fan to feed the pulverized coal and air mixture to the furnace.
Since the core sector industry manufacturing plants are constructed away from large
cities and close to the mines, the vast majority of the public is unaware of the ID /
FD fans used in these large factories.
There is one more dimension to these fans, as these fans are used in moving large
volumes of air (sometimes toxic fumes) and also a mixture of air and fine particles of
pulverized coal, the preferred type of fan in this situation are the centrifugal fan.
This is possible due to the design of the centrifugal fans.

6. In a centrifugal fan, the impeller is the part that faces the air and it changes the air
direction by 90 degrees. This change in air direction many times enables the flow of
air into a piped inlet or exhaust air. The rest of the critical fan components like the
motor, shaft, the belt are not in direct interaction with the air flows, so this fan
design allows only the impeller, blades, and housing to interact with the airflows.
This makes the fan construction very durable and able to work in difficult conditions.
Once a centrifugal fan has proven its mettle as a process fans in the various key
manufacturing operations in core sector industries. It will not be surprising that even
in smaller manufacturing plants, the engineers would use the rugged and durable
design of the industrial centrifugal fans for other operations after reducing the scale
and making other customizations to fit the process.
