Yuke Oil-Coal Dual-Purpose Burner Case Study: Cutting Energy Costs
Case Details
Background and Heating Challenges
Industrial processing plants continuously seek ways to lower operational expenses without sacrificing heat output or product consistency. A major manufacturing facility previously operated clean oil and natural gas heating systems across its primary production lines. While these fuels provided reliable combustion, sharp price increases drastically inflated the plant's overall energy overhead.
To protect profit margins, facility management decided to transition toward more affordable fuel sources. However, standard coal systems often struggle with incomplete combustion, low thermal efficiency, and excessive emissions. The plant needed an advanced heating setup that could burn coal efficiently while retaining the flexibility of oil firing. To solve this challenge, the facility upgraded its heating system to the Yuke oil-coal dual-purpose burner.
The Solution: Direct Coal Injection and Cyclone Combustion Technology
The Yuke oil-coal dual-purpose burner combines fuel versatility with advanced combustion engineering to maximize heat generation from pulverized coal.
Direct Coal Injection Technology
Rather than relying on indirect coal feeding methods, the Yuke burner employs direct coal injection technology. Pulverized coal enters the combustion zone directly under controlled air transport, ensuring rapid ignition and immediate heat response. This direct feed approach boosts overall thermal efficiency and reduces energy transmission losses during operation.
Cyclone Burner Head Design
To ensure complete combustion of the injected coal powder, the burner features a specially engineered cyclone burner head:
-
Rotational Airflow: The cyclone structure creates a strong vortex pattern as coal powder and secondary air enter the burner tip.
-
Extended Residence Time: The swirling movement holds coal particles in the high-temperature zone longer, allowing full volatile release and complete carbon burn.
-
Optimized Flame Stability: The cyclone air pattern establishes a stable ignition core, maintaining steady heat distribution across the combustion chamber.
| Heating Method | Operating Cost Comparison | Primary Efficiency Feature |
| Natural Gas Firing | Highest baseline cost | Standard gas burner nozzles |
| Oil Firing | ~3x higher than Yuke coal firing | Standard oil atomization |
| Yuke Oil-Coal Dual Burner | Lowest operating cost | Direct injection & cyclone burner head |
Key Advantages and Operational Benefits
Installing the Yuke oil-coal dual-purpose burner provided the processing plant with three core operating advantages:
-
Massive Cost Savings: Transitioning to coal-firing mode slashed fuel expenses by roughly two-thirds compared to oil firing and by nearly four-fifths compared to natural gas firing.
-
Superior Thermal Efficiency: Direct injection paired with cyclone combustion ensured full coal burn, achieving high heat recovery rates with minimal unburned carbon waste.
-
Dual-Fuel Flexibility: The dual-purpose design allows plant operators to switch between fuel oil and pulverized coal based on fuel market prices and operational needs.
Measured Results and Impact
Following the commissioning of the Yuke oil-coal dual-purpose burner, the facility logged significant performance improvements across all operational metrics:
-
Energy Expenditure Drop: Fuel overhead dropped by approximately 66% compared to oil and nearly 80% compared to natural gas, resulting in immediate cost recovery.
-
Higher Heat Output: The cyclone burner head design maximized coal burn rates, delivering steady, high-temperature heat output for production lines.
-
Enhanced Plant Flexibility: Dual-fuel capabilities ensured continuous operation regardless of natural gas supply shifts or oil price spikes.
By combining direct coal injection with a cyclone-designed burner head, the Yuke oil-coal dual-purpose burner delivered superior thermal efficiency, flexible operational control, and substantial long-term fuel savings.
