ID fan - definition - English - Glosbe

An ID fan will draw the flue gas out of the boiler through the air heater and air pollution equipment and then exiting up through the stack. The operating temperatures of the ID fans will require thermal insulation for personnel protection and may also require acoustical sound and noise protection.

Causes for Flame Failure in a Boiler and Operator Action

Maintaining a good flame in a boiler is the key to a good boiler performance. Unstable flame is always a threat for boiler furnace explosion, which can lead to a large outage of boiler and loss. There are many causes that can contribute to boiler flame failure. Hence it has become a practice of all boiler designers to interlock purging the boiler with boiler start-up.

What is the function of economizer in boiler? |

A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler
