Understanding the Impact of Excess Air - Firebrid

The chemically ideal amount of air entering a furnace is just enough for all the oxygen in the air to be consumed. However, this ideal (known as the stoichiometric air-to-fuel ratio) is difficult to reach because fuel and air don’t completely mix, meaning that a certain amount of excess air will always be necessary for complete combustion.

2014-4-28 · The main cause of heat loss with the process is that taken away by nitrogen. Therefore, to achieve maximum efficiency the excess air should be kept to a minimum. However there is a limit to the reduction in the excess air in that the combustion process must be fully completed within the furnace and within a finite time.
