Products Description
Low-Temperature Coal Pyrolysis Plant
The Low-Temperature Coal Pyrolysis Plant is an independently-developed batch-type horizontal-rotary pyrolysis unit by Aotewei for low-rank coal upgrading. It is applicable to feedstocks such as lignite, bituminous coal and coal slime. Through oxygen-isolated low-temperature pyrolysis technology, raw coal is converted into coal tar, coal gas and semi-coke. It realizes co-production of multiple products to maximize coal-resource value. Flexible capacity options are available for coal-resource bases and coal-chemical demonstration projects.

Features
① Low-temperature oxygen-isolated pyrolysis for guaranteed product quality
Adopts strict oxygen-isolated low-temperature pyrolysis process to prevent excessive cracking of coal-tar components. It produces high-quality coal tar and high-strength semi-coke and realizes graded conversion of organic substances in coal.
② Horizontal rotary reactor for even material heating
Horizontal rotary reactor with external-gear-ring transmission. Coal particles keep tumbling during pyrolysis to avoid local over-heating and caking. It accepts coal feedstock with wide particle-size range and delivers stable pyrolysis performance.
③ Multi-stage composite condensation system for high tar-recovery rate
Integrates cyclone dust-removal, tubular condensation and oil-mist-capture units. It effectively separates coal dust from volatile matters, reduces tar carry-over loss, improves coal-tar yield and delivers low-ash clean-grade tar.
④ Independent coal-gas circulating combustion system for energy recovery
Purified pyrolysis coal gas is fed back to combustion chamber as heating fuel to greatly cut external-fuel consumption. Adjustable air-fuel ratio enables stable and controllable furnace-temperature.
⑤ Modular composite structure for flexible expandable configuration
The main reactor, dust-removal, condensation and gas-combustion modules are independently engineered. Customers may add coal crushing-screening, semi-coke cooling and deep tar-filtration modules later according to project budget and raw-coal conditions.
Advantages
① Multi-product co-production for sound comprehensive economic returns
One single unit yields three high-value outputs: coal tar, semi-coke and pyrolysis coal gas. Semi-coke can be sold for metallurgy, carbon-material production or as clean fuel. Coal tar can be further refined into heavy fuel oil. Diversified revenue mitigates market risks brought by single-product price fluctuation.
② Broad coal-type adaptability to fully utilize low-value coal resources
Compatible with lignite, long-flame coal, non-caking coal and coal slime. It upgrades low-rank coal which is hard for long-distance transport and direct combustion, and realizes on-site value-adding for coal-mine waste resources.
③ Atmospheric-pressure operation with high-level safety
The whole plant runs under atmospheric pressure without high-pressure hazards from pressure vessels. Real-time monitoring sensors for temperature, pressure and flue gas are fitted together with abnormal-alarm functions to enhance operational safety.
④ Self-produced coal-gas heating lowers operating costs
Most heat comes from combustion of self-generated pyrolysis gas. Only a small quantity of auxiliary fuel is required for initial ignition. Long-term fuel expenditure is greatly reduced compared with systems relying fully on external fuel.
⑤ Easy-to-maintain structure for extended service life The reactor is fabricated from high-temperature-resistant pressure-vessel steel plate. Key rotating components adopt wear-resistant alloy treatment. Manholes and inspection ports are reserved for convenient regular internal inspection and slag-cleaning work.

Application Scenarios
- Coal-mine resource-base projects: Deployed adjacent to open-pit or underground coal mines to locally process on-site low-rank coal and coal slime. Produced semi-coke and coal tar are sold outward, cutting long-distance raw-coal transport costs and improving overall mine profitability.
- Coal-chemical deep-processing enterprises: Serves as pre-treatment unit for coal deep processing to recover coal-tar in advance. Semi-coke is sent to subsequent gasification and combustion procedures to build a circular coal-chemical industrial chain.
- Municipal & industrial clean-fuel projects: Produces premium smokeless semi-coke as substitute for raw bulk coal for industrial boilers, civil heating and ore smelting, assisting local authorities in clean-energy transition.
- Coal-resource-oriented industrial parks: Acts as core pyrolysis unit inside coal-chemical parks, matching with tar distillation and carbon-material deep-processing enterprises. It shares park utilities and enjoys preferential park policies.
- Coal-technology R&D & demonstration bases: Used for coal-pyrolysis process research, adaptability tests for various coal types and new-technology demonstration. It supports multi-parameter experimental tests for coal samples.
Packing & Shipping
Packing Method:
Reactor surface is coated with high-temperature anti-rust paint and wrapped with heavy-duty waterproof tarpaulin with pre-reserved lifting lugs. Gear rings, supporting rollers and wearing parts receive separate anti-collision protection. Electric-control cabinets, sensors and precision instruments are packed in shock-proof and moisture-proof plywood wooden crates. Pipes, gaskets, fasteners and spare parts are sorted and fixed on export pallets. English-language operation manuals, process-flow drawings, assembly drawings and detailed packing lists are supplied together.

FAQ
Q1: What coal types are suitable? What is the regular processing capacity?
A: Mainly applicable to lignite, long flame coal, non caking bituminous coal and coal slime. Standard single batch throughput ranges from 6 10 tons. Highly caking coking coal is not suitable. A coal sample analysis report is required for accurate product yield prediction.
Q2: What products can be obtained from raw coal pyrolysis and what are the yield ratios?
A: Output varies with raw coal quality. Reference range: coal tar 6 12 %, semi coke 55 70 %, pyrolysis coal gas 12 20 %. Output proportions differ significantly among various coal types.
Q3: Does the equipment require non stop 24 hour running?
A: This is batch type equipment. Intermittent production is allowed according to raw coal supply and product sales conditions. Continuous non stop operation is not mandatory.
Q4: What site and foundation requirements are there for installation?
A: A 120 220 ㎡ hardened workshop area is required. Medium load concrete foundation is needed (higher load bearing requirement than plastic / tyre pyrolysis plants). Geological data shall be provided for foundation drawing design. Good ventilation and drainage systems are necessary for the site.
Q5: Can coal crushing screening and semi coke cooling systems be added at a later stage?
A: Yes. The equipment reserves interfaces for front end coal pre treatment and back end semi coke post processing modules. Auxiliaries can be added without modifying the main reactor body.
Q6: What are the warranty terms?
A: 1 year whole set warranty for non human caused damage; 3 year warranty for main reactor body. Consumable wearing parts are supplied at cost price on a long term basis.
