The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its longitudinal axis. The process feedstock is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down toward the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil, pulverized petroleum coke or pulverized coal.
Kiln shell:
This is made from rolled mild steel plate, usually between 30 to 100 mm thick, welded to form a cylinder which may be up to 120 m in length and up to 6 mtr in diameter.
Refractory lining:
The purpose of the refractory lining is to insulate the steel shell from the high temperatures inside the kiln, and to protect it from the corrosive properties of the process material. It may consist of refractory bricks or cast refractory concrete, or may be absent in zones of the kiln that are below approximately 250 °C.
Tyres and rollers:
Tyres, sometimes called riding rings, usually consist of a single annular steel casting, machined to a smooth cylindrical surface, which attach loosely to the kiln shell through a variety of "chair" arrangements. These require some ingenuity of design, since the tyre must fit the shell snugly, but also allow thermal movement. The tyre rides on pairs of steel rollers, also machined to a smooth cylindrical surface, and set about half a kiln-diameter apart.
Drive Girth gear & Pinion:
The kiln is usually turned by means of a single Girth Gear surrounding a cooler part of the kiln tube, but sometimes it is turned by driven rollers. The gear is connected through a gear train to a variable-speed electric motor. This must have high starting torque to start the kiln with a large eccentric load. A 6 x 60 m kiln requires around 800 kW to turn at 3 rpm. The speed of material flow through the kiln is proportional to rotation speed, and so a variable speed drive is needed to control this.

Rotary kilns are a primary source of CO2 emissions. There seems no attempt to try to make them fuel efficient. Why isn't this inside an insulated building shell to retain process heat? Why isn't end-of-process cooling air being collected and used to warm the incoming material? Why are these open air where it is exposed to rain, which requires more fuel to maintain process temperature?

Hi all
I request for your help to teach me how to produce calcined petroleum coke We have a factory producing calcined coke using a rotary kiln, and when we produce it, it wastes too much, about 45% is lost. Can you tell me how much the inlet and outlet temperature of the furnace should be, the rotation speed of the furnace, and even the air required by the furnace, and how much the damper between the furnace and the incinerator should be. thank you
