Lime Kiln - an overview | ScienceDirect Topics
Kiln fuel demand (heavy fuel oil, natural gas or bio-gas produced in a gasification plant using waste wood and bark) is approximately 2.0–2.8 GJ/adt. Total power demand, including clarifier, filters and the electrostatic precipitator for lime kiln, is approximately 40 kWh/adt.

Activated Carbon: A Critical Component in Water
Activated carbon can be regenerated, meaning that the "spent" carbon can be processed (typically in a rotary kiln) to be reused; the adsorbed components can be desorbed, and the spent carbon reactivated, allowing it to be reused repeatedly. Not all activated carbons are reactivated (powdered activated carbon is typically disposed of).

The cement kiln
The kiln is made of a steel casing lined with refractory bricks. There are many different types of refractory brick and they have to withstand not only the high temperatures in the kiln but reactions with the meal and gases in the kiln, abrasion and mechanical stresses induced by deformation of the kiln shell as it

Cement kiln - Wikipedia
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
