bed kiln Demonstration FBK energy use is expected to be 10 to 15 percent lower than that of conventional rotary kilns. (2004); NO x emissions are reduced to 0.77 kg/tonne clinker, compared to 2.1 to 2.6 kg/tonne NEDO clinker for conventional kilns, because of lower combustion temperatures in the FBK (Worrell and Galitsky 2004).
The first 20-25% (100-150 feet) of a wet process kiln is devoted to evaporating the water used for slurrying. This results in added water content and lower temperature of the exhaust gas compared to dry process kilns. Generally, wet process kilns require 5.5 to 6.0 x 106 Btu per ton of clinker produced, while dry kilns require about 4.5 to 5.0.

The rotary kiln rotates at the speed of 1 to 3 revolution per minute (RPM). The raw mix in the kiln melts first into liquid form and then transforms into nodules due to the effect of the rotation of the kiln. There are two zones inside the kiln, namely calcining zone and burning zone.
The afterburner chamber handles the off-gases from: (1) 2 rotary kilns without burning additional liquids, or (2) 1 rotary kiln and in addition 2.4 t/h liquid wastes with a net calorific value of 5200. These liquids are burned in the side walls. The vertical gas velocity is 3.5 m/s in the afterburner chamber at a thermal load of 25 Gcal/h.
