Swapan Basu, Ajay Kumar Debnath, in Power Plant Instrumentation and Control Handbook, 2015. 2.07.2 Induced Draught Fans. An induced draught fan (ID fan) is provided to maintain a negative pressure in the furnace by sucking the products of combustion from it with a slight positive pressure at the discharge end vis-à-vis the bottom of the chimney/stack.
We are offering Draft Fans to our clients.Draft Fans is basically mentioned here for Induced draft fan and Draft Fans is always located between dust collector and chimney.Draft Fans will take the hot flue gases from furnace via dust collector (dust separation system or Fume Extraction system) and will deliver to chimney.Draft Fans will handle the flue gases i.e. hot air.
Induced draft fans or ID fans are used in systems such as steam boilers and thermal oil heaters to draw out and remove flue gases from combustion chambers, by creating a vacuum of negative air pressure (typically -10 mm Hg). This is achieved by using a blower to to suck air through the combustion chamber and the rest of the system, before ...
An induced draft fan (ID fan) is engineered to maintain a negative pressure in the furnace by sucking the products of combustion from it with slight positive pressure at the discharge end from the bottom of the chimney/stack.

Today's furnaces are equipped with a number of different devices that help improve their performance.
An induced draft tower is a type of mechanical draft tower which has one or more fans, located at the top of the tower, that draw air upwards against the downward flow of water passing around the wooden decking or packing. Since the airflow is counter to the water flow, the coolest water at the bottom is in contact with the driest air while the ...
The induced draft fan is a fan which generates negative pressure through the rotation of the impeller, and then extracts air from the equipment. Normally, install it at the end of the boilers in order to extract hot flue gas in the furnace. In daily life, Usually divide the fans into induced draft fans and blowers according to the positive and negative pressure usage.
Induced Draft. Fans that are used to evacuate a space or create negative air pressure in a system are referred to as induced draft fans. Occasionally, manufacturing spaces are required by specifications to be maintained at a specific negative pressure. An induced draft is also used to identify the combustion process used in large boilers.

This Induced draft fans for large-scale power station boilers are generally fixed-blade or movable-blade adjustable axial fans. And, the lifting force generated by the impeller rotation is to introduce the flue gas in the boiler into the desulfurization island or chimney in the axial direction.

The induced draft fan is situated above the bundle, creating negative air pressure to draw the air through to the next step of the process, which could be another application like a dryer or an air treatment system for pollution control. It could also be the exhaust to the outside air. They can work in concert with forced draft fans …
2.07.2 Induced Draught Fans. An induced draught fan (ID fan) is provided to maintain a negative pressure in the furnace by sucking the products of combustion from it with a slight positive pressure at the discharge end vis-à-vis the bottom of the chimney/stack. This positive pressure, assisted by the stack effect of the heated chimney (∼120 ...
Industrial induced draft fans operate by focusing the pressure and volume at the inlet of the fan to pull air through a system. It's not always either-or. Forced draft and induced draft fans often work in concert to maintain efficient and steady air pressure and control the flow using VFDs, dampers, & other accessories.
