Water evaporation In wet-process kilns, and their derivatives, water must first be driven off. In a wet-process kiln, calcining takes place after the water has been driven off, about a third of the way down the kiln. In the more modern pre-calciner kilns, the feed is calcined prior to entering the kiln.

After one revolution of the kiln we can observe line separation. By measuring this line separation we can read the value of creep. This parameter can be easily recalculated into under-tire clearance (gap). Creep divided by 3,14 (Pi) gives us the gap. For most kiln producers tolerance for under-tire clearance is between 3 to 6 mm in hot condition.

The energy efficiency of cement plants strongly depends on the type of kiln used for clinkerisation [49]. Cement kilns have evolved from long wet kilns to state-of-the-art dry kilns with a calciner, a 6-stage preheater and a high-efficiency cooler. Biomass can be utilised as a fuel in both old wet kilns and modern dry kilns.

Even in a well-baffled kiln, there will be some losses around the ends of the boards. And if you have a pile of random length wood, or bundles or differing lengths, these can be even higher. When we calculate estimated air velocity, we might assume as high as 30% losses, depending on the load configuration the customer is expecting.
