Cement and Lime Kilns
Some cement kilns are the wet "slurry" type. Slurry of raw materials is fed directly into the kiln. The temperature at the inlet is considerably less than the dry feed process. Also the kiln is much longer to allow sufficient time for drying before calcination. Figure 1 is a schematic of a typical cement plant. The tremendously high temperature

Cement Plants | Kidde Fire Systems
The Cement/Lime industry has had to search for a way to reduce costs and this has resulted in the near standardization of coal-fired (or coke) systems for firing up the kiln. These systems are indirect-fired, where coal is crushed in mills/pulverizers, then classified by size for collection as a fuel or dust through a heated air conveyance network.

It is known that a large percentage of indirect-fired kilns, particularly in Europe, operate with tip velocities of between 70-83 m/s (14,000–16,500 ft/min) and show exceptionally good flame patterns. However, direct-fired kilns more often are forced, by system design, to operate with velocities of between 45-66 m/s (9,000–13,000 ft/min ...
