PLC Control Regenerative Burner Combustion System Touch Screen Regenerative Burners For Aluminum Melting Furnace
PLC control regenerative burning system for aluminum melting furnace
Regenerative combustion system is automatic operated by PLC, a multicolour touch screen displays aluminium temperature, furnace chamber temperature & regenerative bed air exhaustion temperature digitally.
Temperature of the flue gas exhausted through regenerative burner is lower than 200℃, flue gas which is less than 10% is exhausted from the bypass flue which is for furnace pressure controlling, the sum discharge temperature is lower than 250℃.
Ignites with natural gas.
Compressive air pressure is 4-6kg/cm2, consumption is 35m3/min.
Main power supply is 380V, 50Hz.
FAQ
1. What are the key points of daily inspection?
Temperature/furnace pressure, gas pressure/combustion status, furnace lining/sealing, degassing system, cooling water.
2. What is the regular maintenance cycle?
Daily: Clean the slag from the furnace mouth/flow channel; inspect the burner, ignition system, and seals.
Weekly: verify thermocouples/temperature control instruments; clean the scale in the water gap of the crystallizer; check the integrity of the filter plate.
Monthly: Conduct a comprehensive inspection of the lining thickness/cracks; calibrate the casting speed and traction synchronization; replace aged sealing rings/gaskets.
Every year: overhaul the furnace body (repair/reline the furnace lining); conduct a comprehensive inspection and maintenance of the casting machinery and electronic control system.
3. Safety precautions?
High temperature protection: Wear high temperature resistant clothing, protective face masks, and heat-insulating gloves to avoid burns.
Explosion protection: Leakage is strictly prohibited in gas furnaces, and regular leak detection is required; moist materials are prohibited inside the furnace to prevent explosions caused by water encountering aluminum liquid.
Emergency response: Equip with dry powder fire extinguishers and dry sand.
