Hi there
I have a questin for the flame.
How the secondary air effect the flame?
How can i see in my kiln, if there is circulating gaseous in the flame.
Does the secondary air influence in the strength of the flame?
Is there any book where i can find some solutions?
thank you and have e nice day.
Secondary air has a large effect on the flame and on the quality. Some plants use a special system to control the cooler (secondary air) together with digital image analysis of the flame to see and influence the effects.
Sec. air influences a lot the plum length and this effects ignition point and thus quality (believe it or not, our customers were astonished about the significancy of this effect too). Thus a lot of the cement plants now are going for the new Side Thermography to analyse the plum length and react to it with the burner settings.
