Explore our premium selection of ASME certified, highly efficient pyrolysis reactor designs engineered for variable solid wastes.
Plastic pyrolysis is a advanced thermochemical process that cracks polymer chains into valuable hydrocarbons under high-temperature conditions (typically 350°C to 500°C) in the complete absence of oxygen. As municipalities and global enterprises face tightening regulations on landfilling and incineration, the demand for cheap plastic pyrolysis reactors that balance economic viability with extreme engineering standards has skyrocketed.
By leveraging custom thermal degradation mechanics, waste polymers including High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE), Polypropylene (PP), and Polystyrene (PS) are volatilized inside our hermetically sealed rotary kiln reactors. The gaseous hydrocarbons are then routed through a multi-stage condenser configuration, yielding high-quality pyrolysis oil, non-condensable syngas (recycled to heat the reactor itself), and solid carbon black residue.
Founded in 1968, Huayuan Tech has established itself as an elite pioneer in waste-to-energy and waste tire and plastic scrap pyrolysis technology. Spanning a massive modern production zone of 209,335 square meters with a total plant workshop area of 98,680 square meters, we host a workforce of over 500 seasoned professionals, with engineering and technical specialists representing 34% of our entire staff.
Huayuan Tech is uniquely equipped with state-of-the-art A-class boiler manufacturing facilities and comprehensive pressure vessel production and testing equipment. Over the decades, we have acquired critical certifications, including the national A-class boilers and A2-class pressure vessel manufacturing licenses, alongside D1D2 pressure vessel design certificates. Our systems have successfully met ISO9001, ISO14001, OHSAS18001 standards, and the prestigious United States ASME certification.
Huayuan Tech has evolved from a pure pressure vessel fabricator into an integrated service provider encompassing research, development, manufacturing, sales, technical consulting, thermal energy systems optimization, contract energy management, and financing. We leverage our engineering heritage to design highly efficient waste plastic and scrap tire pyrolysis machines.
By implementing a closed-loop design, our systems recover combustible non-condensable gases to feed the combustion chamber directly. This slashes primary fuel consumption, drastically lowering operating costs for global waste management firms. Whether you run batch, semi-continuous, or fully continuous systems, our reactors deliver optimized heat transfer and high-efficiency carbon black discharge.
Procuring pyrolysis hardware from a top-tier Chinese factory offers unmatched structural advantages, cutting-edge thermal engineering, and optimized capital expenditures.
Chinese heavy manufacturing hubs provide immediate access to specialized boiler-grade steel plates (such as Q245R, Q345R, and 310S stainless steel) at significantly reduced material costs. This allows us to offer cheap plastic pyrolysis reactors without compromising structural thickness or heat resistance.
Leading factories like Huayuan Tech adhere to strict international pressure vessel codes. With national A-class boiler licensing and American ASME stamps, our plastic pyrolysis reactors pass the most stringent safety inspections in North America, Europe, and Australia.
With massive workshop footprints (98,680 sqm of indoor manufacturing space at Huayuan) and specialized automatic submerged arc welding lines, we deliver faster lead times and higher weld precision compared to smaller global competitors.
Trace the development journey of Huayuan Tech as we evolved from a regional boiler repair workshop into a global high-tech pyrolysis powerhouse.
Huayuan Technology initiated development of basic boiler technologies in limited factory workshops.
Restructured as Linyi County Boiler Manufacturing and Repair Factory under the Linyi County Industrial Bureau.
Renamed Linyi Boiler Factory. Merged with Linyi Auto Parts Factory and relocated to Tongda Road for expansion.
Successfully restructured into Linyi Boiler Co., Ltd., laying the foundation for modern corporate management.
Obtained national A-level boiler manufacturing license, ISO certifications, and launched our first batch model waste tire pyrolysis systems.
Moved to our current 220-acre facility in Zaoyuan Town Industrial Park. Commenced R&D on continuous-feed pyrolysis technologies.
Successfully commercialized the continuous screw-running pyrolysis system. Obtained national High-Tech Enterprise status and ASME certificate.
Our manufacturing processes are audited annually to meet the highest safety, environmental protection, and thermal pressure standards worldwide.
From regional waste plastic sorting plants to high-volume refinery-grade feedstocks, we adapt our thermal reactors to fit local ecological landscapes.
Integrating municipal solid waste (MSW) sorting lines with rotary kiln pyrolysis reactors to redirect municipal plastic waste away from saturated landfill sites, converting negative-value waste into profitable fuel oil.
Providing heavy industrial companies with semi-continuous carbon black refining plants and waste heat boilers, allowing onsite energy recovery while keeping emissions well below local legal thresholds.
Partnering with petrochemical giants to produce high-purity plastic pyrolysis oil. This oil serves as a circular cracker feedstock to manufacture brand-new food-grade packaging polymers.

Our reactors successfully handle a wide range of plastic polymers, including Polyethylene (PE), Polypropylene (PP), and Polystyrene (PS), which yield high-quality, high-viscosity oil. However, polymers containing chlorine or nitrogen (such as PVC and PET) must be limited or pre-sorted out. Processing PVC releases highly corrosive Hydrochloric Acid (HCl) gas, which requires custom de-chlorination pretreatments to protect the reactor shell.
Oil yield depends heavily on the feedstock composition. Pure PE and PP plastics can produce an oil yield of up to 80% to 90%. Mixed municipal plastic wastes typically generate between 50% and 70% oil yield, with the remainder being converted into non-condensable syngas (15% to 20%) and solid carbon black (10% to 15%).
Huayuan Tech reactors feature dual safety fail-safes: automatic pressure relief valves, a water lock sealing system to prevent gas backflow, real-time temperature and pressure monitoring sensors at multiple zones, and an explosion-proof dry-type flame arrestor. Our A-class boiler-level quality ensures the reactor vessel resists high-pressure build-ups.
Plastic melts into a highly viscous mass before vaporization, which can lead to severe coking on the inner walls. Our reactors utilize continuous inner scraping blades and advanced rotary dynamics. These keep the liquefied polymer in constant motion, facilitating uniform heat transfer and preventing localized overheating and carbon build-up.
With proper operational maintenance, our reactors fabricated from high-grade Q245R steel have a service life of 6 to 8 years. Fully continuous models equipped with premium alloy steel liners can operate efficiently for over 10 years before requiring structural shell maintenance.
