Rotary Reactor for Pyrolysis Plants
Rotary Reactor for Pyrolysis Plants
The Rotary Reactor is the heart of a pyrolysis system, specifically engineered for the thermal decomposition of organic materials in an oxygen-free environment. This high-efficiency rotating drum reactor facilitates the conversion of waste materials such as plastic, rubber, biomass, or tire waste into valuable end products like pyrolysis oil, syngas, and carbon black. Its rotary design ensures continuous mixing and uniform heat distribution throughout the reaction chamber, leading to optimized yield and enhanced thermal efficiency.
Constructed from high-grade alloy steel or stainless steel, the rotary reactor is designed to withstand extreme temperatures and corrosive environments, offering durability and long operational life. The drum is typically mounted on rollers and slowly rotated by a heavy-duty drive system. This rotation ensures even heating, prevents localized hot spots, and avoids material buildup.
Harsha Engineers India customizes rotary reactors to meet the specific requirements of pyrolysis operations, providing systems that can handle various feedstocks, batch or continuous operation, and integration with condensation units, gas cleaning systems, and control panels for complete process automation.

A Rotary Pyrolysis Reactor operates on the principle of thermal decomposition. The rotating reactor receives waste materials like tires, plastic, rubber, biomass, and so on and heats them in an oxygen-free environment. This controlled process breaks down long-chain molecules into useful by-products like fuel oil, syngas, carbon black, and steel wire (in the case of tires). The rotary motion ensures uniform heating, continuous mixing, and consistent output quality.
- Plastic Pyrolysis Plants – convert plastic waste into fuel oil and gas.
