TRT Axial Flow Rotor Blades are specifically designed for investment in converting the energy released from Blast Furnace Top Gas Recovery Turbines (TRT) into rotational inertia (mechanicals). They have been precision-engineered with unique aerodynamic characteristics that help to maximize the potential for conversions, as well as minimize erosion due to the deterioration of the high-temperature, high-impurity combustion products.

Key Differentiators:

• Material Strength: Made from high-temperature resistant alloys, they outperform standard stainless steel blades in longevity under extreme thermal stress. 
• Aerodynamic Efficiency: Optimized for axial flow, these blades provide up to 5% higher turbine efficiency compared to radial or mixed-flow designs. 
• Versatile Application: Ideal for both dry and wet gas recovery units in steel plants, including large furnaces up to 5050 m³. For example, the 33 MW dry gas recovery units at Zhanjiang Steel’s No. 1 and No. 2 blast furnaces use these blades. 
• Adaptable Parameters: Adjustable blade angles and profiles allow operation under high-temperature and high-impurity industrial gas conditions, outperforming standard off-the-shelf designs in durability and efficiency. 

Specification Evolution

High-Temperature Material Enhancement
TRT Axial Flow Rotor Blades utilize advanced high-temperature alloys, offering significantly better thermal resistance and service life than conventional stainless steel blades used in standard turbine systems.

Optimized Axial Flow Design
Compared with radial and mixed-flow blades, the axial flow structure delivers smoother gas transmission and improved aerodynamic efficiency, helping maximize BFG energy recovery.

Expanded Industrial Compatibility
Designed for both dry and wet TRT systems, these blades are suitable for large-scale blast furnaces up to 5050 m³ and can be customized for different operating environments. Conventional blades are typically limited to standard turbine applications.

Higher Energy Conversion Efficiency
Through optimized blade profiles and adjustable parameters, TRT Axial Flow Rotor Blades can improve turbine efficiency by up to 5% under the same operating conditions.

Improved Resistance to Harsh Gas Conditions
The enhanced blade structure provides stronger resistance against erosion caused by high-temperature, impurity-rich blast furnace gas, reducing maintenance frequency and extending operational cycles.

These blades are uniquely suited for modern steel plants aiming to maximize energy recovery from blast furnace gases while minimizing downtime and maintenance costs.
