What is Tire Aerobic Calcination Equipment?

Waste tire disposal is a persistent environmental challenge, and aerobic calcination offers a solution with the help of specialized equipment. In this blog, we’ll explore the key equipment used in the aerobic calcination of tires–pyrolysis furnace.

Rotary Kilns

Rotary kilns are the core equipment in tire aerobic calcination. They are long, cylindrical, slightly inclined vessels that rotate slowly. Tires, along with any necessary additives, are fed into one end of the kiln. As the kiln rotates, the tires move gradually through it. The interior of the kiln is heated to high temperatures, typically in the range of 800 – 1200°C, by burners located at the discharge end. The oxygen – rich air is introduced into the kiln, enabling the tires to undergo combustion. The slow rotation ensures that all parts of the tires are evenly exposed to heat and oxygen, facilitating complete combustion. This equipment is highly efficient in handling large volumes of tires and can operate continuously, making it suitable for industrial – scale tire disposal.

Combustion Chambers

Adjacent to the rotary kiln, combustion chambers play a crucial role. They are designed to support and enhance the combustion process. After the tires start to burn in the rotary kiln, the partially combusted gases and particles enter the combustion chamber. Here, additional air is introduced to ensure that any unburned hydrocarbons and other combustible materials are completely oxidized. The combustion chamber is equipped with advanced burner systems that can precisely control the temperature and air – fuel ratio. This precise control not only maximizes the combustion efficiency but also helps in reducing the formation of harmful pollutants such as carbon monoxide and unburned volatile organic compounds.

Heat Exchangers

Heat exchangers are an essential part of the tire aerobic calcination setup. Their primary function is to recover the heat generated during the combustion process. There are two main types of heat exchangers used: recuperative and regenerative. Recuperative heat exchangers transfer heat from the hot exhaust gases to the incoming air or other heat – absorbing fluids. This pre – heats the incoming air, which is then used in the combustion process, reducing the energy consumption required to heat the air to the combustion temperature. Regenerative heat exchangers, on the other hand, use a heat – storing medium, such as ceramic bricks. The hot exhaust gases heat up the medium, and then the incoming air is passed through the heated medium to be pre – heated. By recovering and reusing the heat, heat exchangers make the aerobic calcination process more energy – efficient and cost – effective.

Dust Collection Systems

During the aerobic calcination of tires, a significant amount of dust and particulate matter is generated. Dust collection systems are installed to capture these particles and prevent them from being released into the atmosphere. Bag filters are a common type of dust collection equipment. They consist of a series of fabric bags through which the exhaust gases pass. The dust particles are trapped on the surface of the bags, and clean air is allowed to escape. Another option is electrostatic precipitators, which use electrostatic forces to attract and collect the dust particles. These systems are crucial for meeting environmental regulations and ensuring clean air emissions from the tire aerobic calcination process.


The equipment used in tire aerobic calcination (pyrolysis furnace) is a complex and integrated system. Rotary kilns, combustion chambers, heat exchangers, and dust collection systems work together to ensure efficient, environmentally friendly, and energy – conscious disposal of tires. As technology continues to evolve, these equipment will likely become even more advanced, further improving the sustainability of the tire – disposal process.
