The working end is a separate part of the Float Furnace. Glass flows through the canal, where it can be e. g. stirred, into the working end for additional conditioning and to establish a laminar glass flow to the float bath or tin bath. The temperature conditioning, of the working end, cools the glass from a temperature of 1315°C (2400°F) at the entrance to 1065°C (1950°F) at the exit.
To improve the temperature uniformity and control HAL High Velocity Burner for Working Ends produces heat in dense loads that circulates the working end for thorough heat and cooling uniformity at the desired rates, enabling faster uniformity. These High Velocity burners function well with ambient combustion air. Nozzles are available in Nickel free high temperature steel.
The burners are ideal for installation on a dedicated Burner Block for an easy mounting to the working end. The High Velocity Burner will work with ultraviolet flame detectors and direct spark allows flexibility in designing the control system. Our high velocity burner incorporates multi-stage combustion for low NOx. Specifically designed nozzles provide cool NOx inhibiting first stage combustion. Final combustion occurs in the second stage area where combustion products exit at velocities of over 80m/s for medium velocity and 120m/s for high velocity.
