air superheating coefficient
Thread Content
I was reading a book today, and it states that the air coefficient should generally be kept between 1.2 and 1.25. If too much air is used, it will raise the furnace temperature; I used to think that more air would help carry away heat. I hope fellow enthusiasts can provide some guidance
When it says air, does it refer to the oxygen in the air?:)
The furnace temperature is high; an excess of air will lower it. To maintain this temperature, more fuel gas is supplied for control purposes, and the excessive overheated air that is expelled results in a high flue gas temperature
Well, there’s a large amount of air; the excess air gets heated, which takes away heat. I’m not sure what considerations were behind the use of water in that process

When fuel control is unstable, and an excess of fuel enters the furnace, high-temperature accidents are likely to occur.
