Natural Gas Regenerative Burner System 3500Kw Regenerative Burners Nano Energy Saving

Nano energy saving regenerative combustion system for aluminum melting furnace

• Air-Gas Ratio: Air and natural gas are mixed in optimal proportions within the burner for complete combustion, eliminating excess combustion and preventing heat storage damage. Unlike traditional systems, our method ensures safety and efficiency by mixing before furnace entry.
• Waste Heat Recovery: With furnace temperatures reaching 1150°C, our system reduces exhaust temperatures below 180°C, recovering residual thermal energy into heat storage drums. This maximizes waste heat utilization compared to traditional systems with exhaust temperatures above 250°C.
• Furnace Pressure Control: Frequency-controlled fans automatically adjust induced draft to maintain optimal pressure, eliminating flame spraying, black smoke, and the need for pressure relief vents.
• Three-Way Valve Technology: Utilizes high-temperature resistant steel for opening/closing cylinders, ensuring zero air leakage and minimal maintenance requirements.
• Safety Performance: Comprehensive safety configuration includes multiple valve components (two shut-off valves and one natural gas filter valve) with automatic safety detection. System performs self-checks within three seconds of startup, immediately cutting gas and sounding alarms for any abnormalities.

Reasons: Poor insulation, heat leakage due to poor sealing, aging burner/incomplete combustion, ash accumulation, and equipment aging.

Solution:

• Insulation: Inspect and repair furnace body insulation layer to reduce heat loss
• Sealing: Replace furnace door/observation window seals to prevent air and heat leakage
• Combustion: Regularly clean burner carbon deposits, calibrate air-fuel ratio, ensure complete combustion; maintain stable gas pressure (0.4-0.6 MPa)
• Operation: Reduce unnecessary shutdowns, maintain continuous production; avoid frequent small-batch melting

Reasons: Erosion of ignition gun, non-discharge electrode, flame detection position deviation, combustion air fluctuation, gas pressure instability, damaged burner brick.

Solution:

• Ignition System: Replace ignition gun/electrode, adjust flame detection probe position
• Gas/Combustion Air: Stabilize gas pressure, clean combustion air pipeline filter, reduce pressure fluctuations
• Burner Brick: Replace damaged burner bricks to enhance flame rigidity

• Temperature/furnace pressure
• Gas pressure/combustion status
• Furnace lining/sealing
• Degassing system
• Cooling water

• Daily: Clean slag from furnace mouth/flow channel; inspect burner, ignition system, and seals
• Weekly: Verify thermocouples/temperature control instruments; clean crystallizer water gap scale; check filter plate integrity
• Monthly: Comprehensive inspection of lining thickness/cracks; calibrate casting speed and traction synchronization; replace aged sealing rings/gaskets
• Annually: Overhaul furnace body (repair/reline furnace lining); comprehensive inspection and maintenance of casting machinery and electronic control system

• High Temperature Protection: Wear high temperature resistant clothing, protective face masks, and heat-insulating gloves to avoid burns
• Explosion Protection: Strictly prohibit gas leakage with regular leak detection; prohibit moist materials inside furnace to prevent explosions from water-aluminum contact
• Emergency Response: Equip with dry powder fire extinguishers and dry sand
