High-velocity galvanizing furnaces are widely used in hot-dip galvanizing plants to heat and maintain molten zinc at uniform and controlled temperatures. These furnaces are ideal for applications in steel structures, automotive components, pipes, and tubing industries.
High-velocity burners generate intense turbulence, ensuring efficient heat transfer, excellent temperature uniformity, and consistent galvanizing quality. This advanced system helps reduce fuel consumption, minimize zinc dross formation, and extend galvanizing kettle life, resulting in lower operating costs and improved productivity.

Our operations are supported by a skilled and experienced technical team that ensures precision design, robust fabrication, and strict quality control.
We are committed to timely project delivery and complete customer satisfaction. Backed by a modern manufacturing facility at Taloja, near Mumbai—the financial capital of India—we deliver customized, energy-efficient, and cost-effective galvanizing solutions to meet diverse industrial requirements.
The combustion system comprises of High Velocity Dual Fuel burners, mounted on the furnace on diagonally opposite corners. The burners fire horizon¬tally along the kettle sides into the formed combustion space, causing the resultant hot products of combustion to flow rapidly around the kettle giving rise to a high degree of heat transfer through the kettle walls to the zinc.
All the burners are fitted with air orifice meters. This enables gas and air flow rates to be monitored accurately and adjusted via variable orifice valves. These meters guarantee accurate air/fuel mixture ensuring continual economic operation. The complete system is modulated by PID controller which recognizes the drop of 0.1°C and provides the signal to increase or decrease the heat input to the chamber.
A high velocity galvanizing furnace is designed to provide uniform, efficient, and controlled heating of molten zinc in hot-dip galvanizing plants. The system integrates advanced burner technology, intelligent controls, and high-performance insulation to ensure consistent galvanizing quality with reduced energy consumption.
High-velocity burner technology generates powerful and turbulent gas flow within the furnace chamber. This turbulence ensures superior heat transfer, rapid heating, and uniform temperature distribution across the zinc kettle, delivering optimum process performance and coating consistency.
In pulse firing mode, burners operate in controlled bursts instead of a continuous flame. This improves fuel efficiency, enhances heat transfer, reduces temperature overshoot, and helps lower NOx emissions, making the system more energy-efficient and environmentally friendly.
The furnace is equipped with PLC / HMI / SCADA-based control systems to manage burner ignition, flame safety, furnace gas temperature, and molten zinc temperature. These systems also incorporate safety alarms such as zinc leak detection, over-temperature protection, and fault diagnostics for reliable and safe operation.
The furnace structure is heavily insulated using ceramic fiber modules and refractory linings. This minimizes heat loss, improves thermal efficiency, and contributes to lower operating costs and extended equipment life.
