Fuel and air are premixed inside the burner before combustion, ensuring optimal efficiency. This prevents incomplete combustion and avoids secondary combustion in the regenerative chamber.

• Extends lifespan of heat storage components
• Low-oxygen combustion technology (5-10% primary air)
• Eliminates safety risks of traditional furnace mixing

Reduces exhaust temperatures from 1150°C to below 150°C, achieving over 90% fuel utilization efficiency and reducing greenhouse gas emissions by 30-50%.

• Fuel-rich/lean combustion technology
• Increases aluminum liquid surface blackness
• Maximizes energy recycling

Equipped with variable frequency drives (VFD) on fans to dynamically adjust induced draft, maintaining stable furnace pressure without pressure relief openings.

• Eliminates flame leakage and black smoke
• Constant air-fuel ratio during switching
• Prevents pollutant generation

Constructed with high-temperature resistant steel and sealing cylinders to minimize air crossover and maintenance requirements.

• Contrasts with traditional four-way rotary valves
• Reduces energy loss
• Minimal maintenance requirements

Automatically adjusts flame intensity based on furnace door position with a dedicated insulation mode for holding periods.

• 1/3 open → medium flame
• 2/3 open → low flame
• Fully open → main burner off (pilot remains)

Heat recovery chamber incorporates nano-insulation materials with fireproof and waterproof protection, ensuring 5-8 year service life.

• Effectively contains heat
• Ensures efficient reuse of residual energy
• Superior thermal performance
