Project Location: Key highway construction site in Uzbekistan
Commissioning Date: April 2026
Core Equipment: MFR-S1000G Dual-Fuel (Natural Gas/Pulverized Coal) Burner (dual-fuel system)
Application: Aggregate drying and heating at asphalt mixing plants
Key Achievements: Enables seamless one-button switching between fuels, reduces fuel costs per metric ton of material by 25%–30%, achieves aggregate temperature control accuracy of ±2°C, meets emission standards, and ensures a 100% first-attempt ignition success rate.
In April 2026, the gas-coal dual-fuel burner (Model: MFR-S1000G) for asphalt mixing plants—independently developed and manufactured by our company—achieved successful ignition on the first attempt at a key highway construction project site in Uzbekistan! After multiple rounds of rigorous load testing, the equipment demonstrated excellent performance across all metrics and has been successfully put into full-load commercial operation.
As a key supporting project for “Belt and Road” infrastructure development in Central Asia, the successful commissioning of ZOOMLINE Machinery’s burner equipment not only marks a further breakthrough for our company’s industrial thermal energy equipment in overseas markets but also successfully provides local construction machinery and highway construction clients with a low-cost, high-efficiency, and environmentally friendly benchmark solution for asphalt mixture production.
As a key hub in Central Asia, Uzbekistan has vigorously promoted the upgrading of its national highway network and infrastructure development in recent years, leading to a sustained surge in local demand for high-quality asphalt mixtures. However, during actual construction, local highway contractors generally face two major challenges:
In Uzbekistan, the supply of natural gas and coal exhibits marked seasonal variations. During winter, securing a stable natural gas supply is challenging and costs are high; conversely, during certain seasons, pulverized coal is abundant and offers significant price advantages. Traditional asphalt plants equipped with single-fuel burners are highly vulnerable to production halts and spiraling costs should a particular energy source become unavailable or its price spike sharply.
Central Asia has a typical continental arid climate characterized by extreme diurnal temperature variations and high levels of wind-blown sand and dust. This places extremely stringent demands on the ignition stability, temperature response accuracy, flow field control, and dust and wear resistance of thermal equipment. Under such conditions, conventional combustion equipment is highly prone to unstable temperature control, coking and wear, and frequent malfunctions.
To address these challenges, our overseas technical team conducted on-site inspections and data modeling to tailor a “dual-fuel (natural gas/pulverized coal)” intelligent hot-air combustion system for the client, thoroughly resolving the issues of energy dependency and climate adaptability.
The MFR-S1000G dual-fuel (natural gas/pulverized coal) burner, which has been successfully commissioned in Uzbekistan, integrates multiple proprietary core thermal energy technologies developed by our company, achieving a dual leap forward in both economic efficiency and process stability:
The system is equipped with a highly integrated smart control module that supports the efficient combustion of both natural gas and pulverized coal. Customers can seamlessly switch between fuels with a single button press based on local seasonal energy price trends and supply conditions. While ensuring continuous production, the comprehensive energy cost per metric ton of material can be reduced by 25% to 30%, significantly enhancing the project’s economic benefits.
The equipment employs advanced multi-stage air distribution design and flow field simulation technology, enabling thorough and uniform combustion of fuel within the drum. Even under the harsh conditions of Central Asia, where temperature fluctuations are extreme, the system can precisely control the drying and discharge temperature of asphalt aggregates within a tolerance of ±2°C. This effectively prevents over-burning or “sandwiching” of aggregates, significantly improving the compaction of the finished asphalt mixture and the quality of pavement laying.
To address the unique arid and dusty conditions of Central Asia, the combustion system features comprehensively reinforced sealing and dust-proof structures, as well as wear-resistant protection for key components. Additionally, by incorporating multi-stage low-NOx combustion technology, nitrogen oxide and dust emissions are significantly reduced, with emission levels fully compliant with both local Uzbek standards and international environmental standards.
Début avril 2026, ZOOMLINE’s team of overseas professional service engineers immediately traveled to the construction site in Uzbekistan to provide guidance on mechanical installation, verify electrical wiring, and conduct integrated system commissioning.
In mid-April, the equipment smoothly entered the trial operation phase and successfully passed the full-load continuous operation test. Real-time on-site monitoring data showed:
Ignition success rate: 100% (Both the initial trial run and subsequent multiple starts were successful on the first attempt)
Fuel Switching Time: The process was smooth and seamless, with no significant temperature fluctuations or pressure surges in the system
Operational Stability: Zero failure rate during continuous full-load operation
The site manager for the Uzbekistan project highly praised the technical performance of our equipment and the dedicated service provided by our engineering team:
“This MFR-S1000G dual-fuel (coal and gas) burner is perfectly suited to Uzbekistan’s actual energy conditions! Not only has it helped us mitigate the risks of rising prices and supply disruptions associated with relying on a single energy source, but its high level of intelligent operation and stable temperature control have provided an extremely robust thermal energy guarantee for the on-schedule progress of our entire highway construction project!
As infrastructure development in Uzbekistan and throughout Central Asia continues to advance, market demand for high-quality, energy-efficient, and intelligent thermal energy equipment for construction machinery is growing rapidly. The successful commissioning of this dual-fuel (coal and gas) burner at the asphalt plant has further solidified ZOOMLINE company’s reputation and brand influence in the fields of overseas industrial thermal energy and construction machinery support.
Looking ahead, our company will continue to deepen our presence in markets along the “Belt and Road” route. Driven by technological innovation and supported by a localized, rapid-response service network, we will provide global customers with more efficient, eco-friendly, and energy-saving comprehensive thermal energy solutions, jointly advancing the high-quality development of the Green Silk Road!
