The emissivity of the rough oxidised kiln shell at 400 degrees C is approximately 0.9. According to my notes emissivity is dimensionless.

What is the emissivity of a kiln's shell? I ask this because i need to know it to take infrared thermography of the surface shell of a kiln.

No, there is no precise formula for the relationship between kiln speed and feed rate. This depends on the degree of preparation (calcination) of the feed at the kiln inlet and the progression of this feed preparation along the kiln length. However, there are "rules of thumb" and guidelines you can use for various kiln process types. What type of kiln are you operating?

Is there a formula for determining the correlation between kiln feed rate and kiln speed?
