Specifications of rotary kiln for calcined petroleum Coke

Rotary kilns reliably calcine oil coke. This equipment transforms raw green coke into high-grade calcined coke. Calcined coke is important for light weight aluminum smelting anodes and various other commercial usages. The kiln operates at very heats. These temperatures remove unpredictable issue and moisture. The process likewise boosts coke density and electrical conductivity.

Rotating kilns for calcined petroleum coke been available in various sizes. Usual covering sizes range from 3 meters to over 4.5 meters. Lengths commonly range 50 meters and 80 meters. The kiln shell is made of strong steel plate. A thick refractory lining protects the inside. This lining withstands intense warmth and chemical reactions. The kiln rotates slowly. Turning rate is flexible. Rate control takes care of the material’s traveling time inside. The kiln rests on a mild slope. Gravity helps relocate the coke via television.

Optimum operating temperature is crucial. The most popular area gets to around 1300 ° C to 1400 ° C. Temperature control is specific. Numerous burners offer the warm. These burners typically utilize gas or gas oil. Some styles approve alternate gas. The coke relocates counter-current to the warm gases. This ensures effective heat transfer. The coke invests 30 to 60 mins inside the kiln. This moment is the house time. Residence time ensures total calcination.

Manufacturing capacity depends on kiln dimension and running parameters. Capacities vary from 10 tons per hour to over 50 bunches per hour. The kiln drive system makes use of durable electric motors and transmissions. Assistance rollers bring the kiln’s weight. Thrust rollers maintain the kiln positioned appropriately. Exhaust gases leave via a big air duct. These gases go to a pollution control system. Dedusting systems capture great coke fragments. Air conditioning systems deal with the hot calcined coke discharge.

Applications of rotary kiln for calcined petroleum Coke

Rotating kilns play an important function in making calcined oil coke. This product is crucial for numerous sectors. The kiln warms green oil coke to high temperatures. This eliminates unpredictable issue and wetness. The result is a pure carbon item with high density and conductivity.

The light weight aluminum sector utilizes calcined petroleum coke greatly. It functions as a carbon source in anodes for aluminum smelting. These anodes conduct power in decrease cells. High quality coke ensures efficient smelting. It also expands anode life. This decreases production expenses for light weight aluminum manufacturers.

Steel making advantages too. Calcined petroleum coke functions as a recarburizer. It includes carbon back into liquified steel. This enhances steel strength and solidity. Factories rely on it for casting mold and mildews. It aids attain exact carbon levels in final steel items.

Titanium dioxide manufacturing requires calcined coke. It fuels the chlorination process. This process converts titanium ore right into titanium tetrachloride. High-purity coke guarantees clean reactions. It stops contamination in the final white pigment.

Graphite electrode manufacturing requires calcined coke. Electrodes conduct power in electric arc heating systems. These heaters thaw scrap steel. Coke supplies the carbon backbone. It offers electrodes thermal stability and conductivity. This allows efficient steel recycling.

Various other fields use calcined petroleum coke. Carbon raisers employ it in iron spreading. It changes carbon content in liquified iron. Chemical processes use it as a lowering agent. Some gas applications exist yet are less usual due to its value.

Rotary kilns enable regular coke high quality. Their design allows accurate temperature control. This ensures uniform calcination throughout the material. Industries rely on this integrity for their procedures.

5 FAQs of rotary kiln for calcined petroleum Coke

Rotary kilns process raw petroleum coke into calcined coke. This removes volatile components. It makes the material suitable for industrial uses. Many people have common questions about this process.

What does a rotary kiln do for calcined petroleum coke?
Rotary kilns heat raw petroleum coke to very high temperatures. They turn slowly. This movement exposes the coke evenly to the heat. The heat drives off moisture and volatile matter. The result is calcined petroleum coke. Calcined coke has higher carbon content. It is more stable.

What temperature is needed inside the kiln?
The temperature inside the kiln is critical. It typically ranges from 1200 to 1400 degrees Celsius. This high heat is necessary. It ensures complete removal of volatiles. It also changes the coke’s crystalline structure. This gives calcined coke its key properties.

Is the process energy efficient?
Modern rotary kilns focus heavily on energy efficiency. They recover heat from the exhaust gases. This recovered heat preheats incoming raw coke. It also heats combustion air. This reuse significantly reduces overall fuel consumption. It lowers operating costs.

What maintenance do these kilns require?
Rotary kilns need regular maintenance. The extreme heat and abrasive coke wear down the refractory lining. This lining protects the kiln shell. Inspections happen frequently. Worn refractory bricks get replaced. The kiln’s drive system and seals also need monitoring. Proper upkeep prevents unplanned shutdowns. It ensures continuous production.

How does the kiln affect final product quality?
Kiln operation directly impacts coke quality. Consistent temperature control is vital. Uneven heating creates inconsistent calcination. The rotation speed and feed rate must be stable. These factors influence the coke’s density and electrical conductivity. Good process control delivers uniform, high-grade calcined coke.
