In July, 2026, Henan ZOOMLINE Machinery Equipment Co., Ltd has successfully delivered a complete MFR-S2000 pulverized coal burner system to a leading road construction enterprise in Ethiopia. The integrated system—comprising a heavy-duty hammer crusher, coal hopper, two high-efficiency coal pulverizers, and the flagship MFR-S2000 pulverized coal burner—will be paired directly with the client’s existing asphalt mixing plant (asphalt batch mix plant) for continuous highway construction operations.
This delivery marks another strategic milestone for ZOOMLINE in the African construction machinery market, showcasing the superior cost-effectiveness, high combustion efficiency, low slagging features, and extended operational lifespan of the MFR-S series coal-fired burner.
As a major economic hub in East Africa, Ethiopia is rapidly expanding its road and transport infrastructure. This growth has created substantial demand for high-capacity asphalt mixing plants. However, aggregate drying and heating require massive amounts of thermal energy, traditionally generated by liquid fuels like heavy fuel oil (HFO), diesel, or natural gas.
For import-dependent nations like Ethiopia, volatile global oil prices and supply chain disruptions severely impact road contractors. Furthermore, underdeveloped natural gas pipelines frequently cause costly project delays.
Heavy Financial Burden: The Ethiopian contractor’s existing asphalt batching plant relied on fuel oil, with fuel costs exceeding 60% of total operating expenses.
Need for Fuel Conversion: To safeguard profit margins, the client sought a dependable asphalt plant burner retrofitting solution using localized pulverized coal to drastically cut energy expenditure.
Tailored to the client’s production capacity and local operating conditions, ZOOMLINE’s MFR-S2000 pulverized coal burner system delivers key technical and economic benefits:
Coal powder remains significantly cheaper than diesel or heavy oil. Industry data demonstrates that converting an asphalt plant to a pulverized coal burner can reduce fuel costs by 60% to 70%. With a maximum thermal output of 14,000 kW and a consumption rate of 700–2,250 kg/h, the MFR-S2000 easily fulfills the continuous thermal energy demands of large-scale asphalt plants.
Standard coal burners require coal crushed to 200 mesh for complete combustion, demanding high-power grinding equipment. ZOOMLINE MFR-S series utilizes advanced German semi-open pulverized coal combustion technology, achieving thorough combustion at just 100 mesh. This significantly lowers electricity consumption, reduces pulverizer wear, and lowers fuel preparation costs.
Conventional coal burners rely on internal refractory bricks, which frequently crack under thermal shock, leading to high maintenance costs and extended downtime. ZOOMLINE MFR-S series features a combustion chamber built with imported heat-resistant steel plate, completely eliminating brick replacement. Furthermore, the specialized air-flow design prevents slag accumulation on inner walls, eliminating the need for daily clinker removal.
Achieving a burnout rate exceeding 98%, the MFR-S2000 ensures rapid ignition and complete coal powder combustion. This high energy conversion efficiency minimizes fuel waste and significantly lightens the filtration load on the asphalt plant’s bag-house dust collector.
Beyond asphalt mixing plants, the MFR-S series burner is widely applicable in rotary drying kilns, industrial boilers, and slag grinding systems, providing high adaptability for future project relocation.
ZOOMLINE provided a complete, turnkey pulverized coal processing and combustion system rather than standalone equipment:
Hammer Crusher: Crushes lump raw coal to <25 mm, optimal for pulverizer feeding.
Coal Hopper: Serves as an automated buffer and feeding unit, ensuring a consistent fuel supply.
Dual Coal Pulverizers (45 kW Class): Efficiently grind coal to the target fineness and convey it to the burner via direct airflow.
MFR-S2000 Pulverized Coal Burner: Generates precise, intense thermal energy directly into the asphalt plant’s drying drum.
This closed-loop system allows fast, plug-and-play installation without requiring third-party coal preparation equipment.
To guarantee quick production startup in overseas markets, ZOOMLINE provided end-to-end service support:
Logistics & Scheduling: Utilizing mature shipping channels to Africa, equipment arrived safely and on schedule.
Technical Installation & Commissioning: Engineers provided both remote oversight and hands-on site support to optimize system parameters.
Operator Training: Client personnel received comprehensive training on coal preparation, flame regulation, preventive maintenance, and troubleshooting.
The successful deployment of the MFR-S2000 coal burner system in Ethiopia reinforces ZOOMLINE’s position as a reliable supplier of asphalt mixing plant thermal equipment and energy-saving burner solutions. By helping clients replace expensive fuel oil with cost-effective coal, ZOOMLINE continues to empower road construction projects worldwide with sustainable, high-efficiency heating technologies.
