Windbox TT Burner

​The Windbox TT Burner (Tangential Tilt Burner) by SAI VLS is a specialized, high-precision combustion component designed for large-scale industrial boilers and thermal power plants. It acts as the critical housing and distribution hub for air and fuel, ensuring that the combustion process is stabilized and efficient.
​Built with heavy-duty fabrication techniques, the Windbox TT Burner is engineered to withstand extreme thermal stresses while maintaining precise control over the “fireball” within the boiler furnace through its unique tangential tilting mechanism.

The Windbox TT Burner is best suited for Utility-Scale Power Plants and Large Industrial Processing Facilities (such as paper mills or chemical plants) that utilize tangential firing boilers. It is the ideal solution for operators looking to improve Superheat and Reheat steam temperature control and those seeking a rugged, low-maintenance combustion system capable of handling high-capacity thermal loads.

Benefits of the Windbox TT Burner
​Enhanced Thermal Efficiency:
By optimizing the air-fuel ratio and distribution, the burner ensures complete combustion, reducing fuel waste and increasing heat output.
​Dynamic Combustion Control:
The tilting (TT) capability allows operators to adjust the vertical position of the fireball, providing better control over steam temperatures.
​Reduced Emissions:
Precise air distribution helps in lowering NOx and CO emissions, assisting industrial facilities in meeting environmental compliance standards.
​Durability and Longevity:
Manufactured using SAI VLS’s robust fabrication standards, these burners are resistant to high-temperature oxidation and mechanical wear.
​Process of the Windbox TT Burner
​Air Integration:
Primary air (carrying fuel) and secondary air (for combustion) enter the windbox from the boiler’s air ducts.
​Distribution:
The internal vanes and dampers within the windbox distribute the air to individual burner nozzles.
​Tangential Injection:
The fuel and air are injected at an angle toward the center of the furnace, creating a rotating vortex or “fireball.”
Combustion Stabilization:
This rotating motion ensures maximum residence time for fuel particles in the high-temperature zone, ensuring thorough ignition and heat release.
