Heat Recovery System for Hot-Dip Galvanizing WEDONE
The WEDONE Heat Recovery System captures usable thermal energy from hot exhaust gases generated by the galvanizing furnace. Instead of discharging all available heat into the atmosphere, the system transfers part of this energy to selected plant processes.
Recovered heat can be used to warm pretreatment baths, support drying operations, produce hot water or preheat combustion air, depending on the exhaust conditions and actual energy demand of the galvanizing plant.
• Recovers usable heat from galvanizing-furnace exhaust gas
• Reduces the energy required by suitable downstream processes
• Can heat pretreatment tanks, process water or drying air
• Combustion-air preheating options available
• Heat exchanger selected for gas temperature and contamination level
• Automatic temperature monitoring and operating controls
• Bypass and safety arrangements customized for furnace operation
• System capacity engineered around available heat and plant demand
• Can be integrated into new or existing galvanizing lines
• Supports lower operating costs and improved overall energy efficiency
Key Advantages
Typical Technical Parameters
● Non-standard customized design according to actual customer requirements.
● Heat-pipe flue gas heat exchanger can recover nearly 20% of furnace heat from combustion exhaust, equipped with a bypass loop for maintenance.
● Skid-mounted design for easy and fast installation on site.
● On-site piping with armored external thermal insulation to prevent heat loss.
● Integrated solvent heating system
Working Principle
The system collects high-temperature exhaust gas from zinc kettles, annealing lines, or furnace systems. Heat exchangers transfer this energy to preheat incoming air, water, or process materials, reducing the need for additional fuel. Advanced control systems ensure stable temperature regulation and optimal energy utilization, enhancing the overall efficiency of the galvanizing line.
Application in Hot-Dip Galvanizing
Heat Recovery Systems are widely used in zinc kettles, annealing furnaces, and RTO systems. By reclaiming thermal energy, they improve overall plant efficiency, reduce fuel usage, and contribute to environmentally sustainable galvanizing operations.
