Combustion Air - an overview ScienceDirect Topics

The combustion air is led to the furnace. The air system consists of components that are used to get air to the boiler furnace. Manufacturing reasons dictate that the furnace is kept close to the surrounding pressure. Therefore blowers are needed to drive air into the furnace. Ducting must be done from where air is drawn to the blowers.

What is a Boiler? E Instruments e-inst.com

A boiler is an enclosed vessel in which water is heated and circulated, either as hot water, steam, or superheated steam for the purpose of heating, powering, and/or producing electricity. The furnace of the boiler is where the fuel and air are introduced to combust; fuel/ air mixtures are normally introduced into the furnace by using burners, where the flames are formed.
