What is a Pyrolysis Chamber?

DOING pyrolysis chamber is a specially designed reactor or enclosed space used to thermally decompose organic materials (such as tires, plastics, rubber, oil sludge, coal tar residue, MSW and biomass waste, etc.) at low temperatures in the absence of oxygen. Under controlled temperature and pressure conditions, the molecular structure of the waste materials breaks down into smaller molecules, generating valuable products such as pyrolysis oil, carbon black, and synthetic gas.

What Can DOING Pyrolysis Chamber Produce?

Pyrolysis Oil (HFO):

Pyrolysis oil, derived from waste materials, boasts a high calorific value and excellent flammability. It's a kind of heavy fuel oil, also called HFO. Its calorific value typically ranges between 40–45 MJ/kg. This oil can serve as industrial fuel for boilers, cement plants, glass factories, steel mills, and other energy-intensive industries. Additionally, DOING has developed a pyrolysis oil distillation technology that further refines pyrolysis oil into non-standard diesel through decolorization and deodorization processes. This non-standard diesel meets diesel engine fuel standards and can power heavy machinery such as trucks, trailers, forklifts, agricultural equipment, and mining vehicles.

Applications of pyrolysis oil

Carbon Black:

Carbon black, produced in powder form during pyrolysis, has a calorific value exceeding that of coal (approximately 25–30 MJ/kg). It can be directly used as solid fuel or pressed into pellets for applications in industrial heating, power generation, and other fields. Furthermore, after activation and processing, carbon black can be used as a reinforcing agent in rubber products or as a filler in plastics and coatings.

Syngas:

Syngas, a mixture of hydrogen, methane, and carbon monoxide, has a calorific value comparable to natural gas (typically 15–20 MJ/m³). After treatment, the syngas can be directly recycled to heat the reactor.

Charcoal:

Charcoal, made from biomass pyrolysis process, has a wide range of applications, spanning from fuel and industrial processes to art and even medicine. It's used as a fuel for cooking and heating, in metallurgy as a reducing agent and in steel production, and in chemical processes. Furthermore, charcoal is used in agriculture, horticulture, activated charcoal making and cosmetics, etc.

The Unique Features of DOING Pyrolysis Chambers

Oxygen-Free Environment: Safe and Stable Operation

The pyrolysis chamber operates under an oxygen-free condition, ensuring no air enters during feedstock loading, heating, and residue discharge. This design not only prevents oxidation and combustion of waste materials but also minimizes safety risks such as explosions. By maintaining a stable internal environment, the pyrolysis chamber ensures consistent reaction outcomes.

Flexible Temperature Control: Precision Adaptation to Various Materials

The pyrolysis chamber can operate within a wide temperature range (typically 300–550°C). By adjusting the temperature, it can efficiently process different types of waste materials. For example, pyrolysis of plastic waste typically occurs at 350–450°C, while rubber waste pyrolysis is optimized at 400–500°C. Precise temperature control ensures maximum resource recovery from waste materials.

Diverse Feeding Systems: Broad Feedstock Compatibility

DOING pyrolysis chambers feature advanced feeding systems capable of handling a variety of raw materials, including plastic, rubber, tires, oil sludge, household waste, medical waste, biomass materials and more.

Heating Mechanisms: Efficient Energy Utilization

The pyrolysis chamber employs direct or indirect heating methods (e.g., fuel oil, natural gas, or pyrolysis fuel oil). Direct heating enables rapid temperature increases, while indirect heating ensures even heat distribution. This dual heating mechanism not only improves heating efficiency but also reduces energy consumption, enhancing the economic viability of the pyrolysis process. Batch and semi-continuous pyrolysis chambers utilize direct heating, while fully continuous pyrolysis chambers utilize indirect heating.

Advanced Gas and Liquid Collection Systems: Maximizing Resource Recovery

The pyrolysis chamber is equipped with a highly efficient gas and liquid collection system. During pyrolysis, volatile gases are separated and condensed into liquid fuel, while residual gases undergo purification and recycling. This system maximizes resource utilization, ensuring that every drop of pyrolysis oil and cubic meter of synthetic gas is effectively recovered.

Robust Emission Control: Environmental Protection Compliance

DOING pyrolysis chambers integrate cutting-edge environmental protection technologies, such as patented exhaust gas deodorization devices and flue gas desulfurization/denitrification systems. These technologies filter harmful substances (e.g., CO₂, SOₓ, NOₓ) from exhaust gases, ensuring emissions meet global environmental standards.

Diverse Design Options: Meeting Diverse Industrial Needs

DOING pyrolysis chambers offer four design types to cater to varying scales and requirements:

Batch Pyrolysis Chamber（1Ton-20Ton/Batch/Set）

Suitable for small-scale to big industrial scale applications (e.g., one batch per furnace per day). This design is ideal for pilot projects or small waste processing facilities, offering simplicity and ease of operation. If you have relative small budget, you can choose it. Besides that, Henan Doing Company also offers multiple sets of batch pyrolysis plants for industrial scales operation, the annual waste treatment capacity of the pyrolysis lines can achieve more than 30,000tons.

Semi-Continuous Pyrolysis Chamber （10-20Ton/Day/Set）

Designed for medium-scale industrial operations, this chamber achieves higher processing efficiency than batch systems. It strikes a balance between equipment investment and operational output, making it a cost-effective choice for many enterprises.

DOING semi-continuous pyrolysis chamber

Continuous Pyrolysis Chamber（15-50Ton/Day/Set）

Tailored for large-scale industrial applications, this design enables continuous feedstock input and product output. It boasts advanced environmental protection and automation features, significantly reducing labor costs and operational risks while meeting high-capacity waste processing demands.

DOING fully continuous pyrolysis chamber

Skid-Mounted Pyrolysis Chamber（100Kg-1Ton/Batch/Set or Customized Capacity）

A compact, integrated design that combines pyrolysis equipment with a mobile skid. This configuration enhances equipment mobility and flexibility, allowing for rapid deployment at different waste processing sites. It is particularly suitable for temporary or decentralized waste processing scenarios.
