AFR Systems
Carbon Black Feeding Systems
What is Carbon Black?
Carbon Black is a fine, powder-like material produced from the incomplete combustion or thermal decomposition of heavy petroleum products such as coal tar, FCC tar, and ethylene cracking tar.
It is widely used in rubber, plastics, inks, paints, and chemical applications, and in cement plants it is increasingly used as an alternative fuel due to its high calorific value and excellent combustion characteristics.
Benefits of Using Carbon Black as AFR (vs. Coal)
- Higher TSR Potential: Carbon black offers a higher calorific value compared to traditional coal, improving the Thermal Substitution Rate when used as alternate fuel.
- Improved Kiln Efficiency: Finer material and higher volatile content ensure quick ignition and stable combustion.
- Reduced Fuel Cost: As a recovered waste material, carbon black provides a lower-cost energy source compared to imported coal.
- Lower Emissions Footprint: Helps reduce overall CO₂ emissions by replacing fossil fuels with waste-derived fuel.
- Consistent Fuel Quality: Processed carbon black has predictable heating value, improving AFR control and kiln stability.
Jumbo Bag Unloading
Jumbo Bag Unloading systems are designed to handle large quantities of carbon black that come in bulk bags (or jumbo bags). These systems offer a cost-effective and efficient solution for plants with limited space and those that require flexible handling options.
Working
- Bag Handling & Positioning: Jumbo bags are securely lifted and positioned above the unloading station using hoists or cranes.
- Dust-Controlled Discharge: Bag contents are discharged into the system via sealed spouts, preventing dust release and ensuring a clean working environment.
- Material Flow Regulation: Integrated valves or feeders regulate the flow of carbon black into downstream conveyors or hoppers.
- Integration with Storage/Feeding Systems: Unloaded material is directed to AFR feeding, batching, or storage systems for further processing.
- Safety & Ergonomics: Designed for operator safety with minimal manual handling and dust exposure.
Benefits
- Dust-free operation for safe handling of fine carbon black powders.
- Controlled material flow ensures consistent feed rates to downstream systems.
- Enhanced operational safety with reduced manual handling.
- Flexible integration into cement plant or AFR co-processing lines.
- Efficient handling of high-volume bags, minimizing unloading time and labour.
Bulker Unloading
Bulker Unloading systems are designed to unload carbon black from bulk transporters or bulk containers (bulkers). This system is optimized for high-capacity, cost-effective operations, making it a preferred choice for large-scale plants or facilities that need to handle large quantities of carbon black.
Working
- Bulker Connection: Bulk containers (bulkers) are connected to the pneumatic unloading system via sealed couplings.
- Vacuum/Pressure Conveying: Pneumatic conveyors transport carbon black from the bulker to storage silos or feeding systems.
- Flow Control: Valves and sensors regulate the material feed to prevent overloading and ensure continuous operation.
- Dust Containment: Cyclones, filters, and sealed lines maintain dust-free conveying throughout the system.
- Integration with Plant Systems: Material is delivered directly to AFR feeders, silos, or dosing systems, ready for co-processing or blending.
Benefits
- Fast, continuous unloading of bulk carbon black with minimal manual intervention.
- Dust-proof pneumatic conveying protects operators and the plant environment.
- High flexibility for direct integration into AFR feeding and storage systems.
- Consistent feed rates ensure smooth downstream processing.
- Reduced handling and labour costs, increasing operational efficiency.
RDF/Biomass Drying
Why Drying Matters
Moisture in RDF, biomass, or waste-derived fuels drastically reduces their calorific value, increases transport cost, complicates storage, and makes firing unstable. Our drying solution — using proven low-temperature belt and conveyor dryers from PH1— removes moisture efficiently, increasing heating value, improving storability, reducing transport weight, and enabling stable AFR firing in your kiln or furnace.
What We Can Dry (RDF / Biomass / Waste-derived Fuels)
- Refuse-Derived Fuel (RDF / SRF / MSW) including mixed municipal and industrial waste.
- Biomass feedstocks: wood chips, sawdust, bark, agricultural residues, bagasse, agro-waste, sludge, and other biomass or waste-derived materials.
- Industrial sludge, sewage sludge, paper sludge and other waste sludges — converting waste to usable dry fuel or RDF/SRF.
Benefits of the PH1 Drying Solution
- Increases Calorific Value & Fuel Quality: By reducing moisture content, the drying line enhances the calorific value of RDF/biomass, enabling higher AFR substitution and more stable combustion.
- Improved Storability & Handling: Dried material is lighter, easier to store, handle, and transport; reduced weight also lowers logistics costs.
- Consistent Fuel Quality Despite Variability: PH1 dryers are engineered to handle highly variable input materials (inhomogeneous waste/biomass) and adapt drying conditions accordingly.
- Energy-Efficient & Environmentally Friendly: Low-temperature belt and conveyor dryers reduce energy consumption; some variants recover heat or utilize waste heat sources, reducing OPEX.
- Better Combustion & Kiln Stability: Uniform moisture reduction and controlled drying improve combustion consistency, reduce clinker/refractory stress, and support reliable AFR usage.
Features of the Drying Systems
- Low-temperature belt / conveyor dryer technology: Suitable for mixed waste, RDF, biomass, sludge, and other feedstocks; ensures gentle, uniform drying without damaging material quality.
- Modular & Customizable Dryers: Dryer types (belt, conveyor, recirculating, mobile) chosen based on input material type, moisture content, throughput, and project needs.
- Heat source flexibility: Dryers can use waste heat, steam, thermal oil, or low-pressure hot water, depending on plant availability — optimizing energy use and lowering operating cost.
- Automated controls & monitoring: Moisture, temperature, and airflow are monitored and controlled to ensure consistent output and efficient drying.
- Dust and emission control options: Many designs include dust reduction, exhaust air treatment or condensation, making the drying process cleaner and environmentally compliant.
