Spiral Furnace with SPW Burner

Aiming to improve energy efficiency

By recovering the waste heat of the conventional spiral furnace without discharging it and reusing it as combustion air for the burner, we have achieved a dramatic improvement in energy utilization efficiency.

Comparison with conventional furnace

Spiral furnaces are designed to optimally circulate heat according to the crucible used by the customer, taking into consideration the space inside the furnace and the pressure inside the furnace.
Furthermore, by providing a flow path to circulate exhaust heat, we succeeded in maximizing the heat exchange function of the burner.
In addition, the exhaust heat path is provided inside the furnace to reduce heat dissipation, further enhancing the energy-saving effect.
