In comparing these tile differences in over­ all specific heat consumption, heat requirements, and heat losses between these kilns can be observed. For the uninitiated, it should be noted that the actual heat required for clinkering the feed, i.e., the true thermal work required, is only about 431 kcal/kg (1.55 MBtu/sh.ton).

 — The earliest kilns in which cement was burned in batches were bottle kilns, followed by chamber kilns and then by continuous shaft kilns. The shaft kiln in a modernized form is still used in some countries, but the dominant means of burning is the rotary kiln. These kilns—up to 200 metres (660 feet) long and six metres in diameter in wet ...

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.
