Ladle Preheating Technology for Metal Production
Ladle Preheating for Increased Efficiency & Reduced Emissions
During combustion, flue gases are mixed into the combustion reaction zone to dilute the reactants. This distributes the combustion process, delays the release of heat and lowers the peak flame temperatures – all of which reduce NOx emissions without compromising efficiency. Mixing flue gases into the flame also disperses energy throughout the entire vessel, ensuring faster, more uniform heating. The dispersed flame contains the same amount of energy but distributes it much more effectively throughout the vessel. Our OXYGON ladle preheating system is available in two versions for different vessel sizes and different levels of flexibility to meet your operation's needs and safety standards.
OXYGON® 400 Preheating System: Capacities from 1 to 20 tons
OXYGON 400 preheating system is a plug & play system that is mounted on the vessel lid and has a nominal power of 400 kW. It is ideal for customers looking for a simple, efficient method of preheating typical foundry vessels with capacities from 1 to 20 tons. The accompanying control system automatically controls the ladle temperature by using an ON/OFF control of the semi-flameless combustion process. When the full power is off during a heating operation, the pilot burner is burning, ensuring the operational safety.
Benefits:
- Predictable, consistent ladle temperature
- Maximum refractory lifetime through controlled combustion
- Greater energy efficiency and lower emissions
- Reduced number of ladles in operation
Features:
- Integrated burner pilot and UV cell
- Leak testing for safety
- Simpler installation vs. air/fuel systems with recuperative/regenerative technologies
- Flow trains for fuel and oxygen
- Semi-flameless combustion
- Programmable heating curves for drying and reheating
- ON/OFF modes
OXYGON® XL Preheating System: Capacities from 30 to 150 tons
The OXYGON XL preheating system is based on the same technology as OXYGON 400 system, but comes with a more advanced control system, as well as a 1.5 MW burner suitable for vessels with capacities from 30 to 150 tons.
The OXYGON XL plug & play system is mounted on the vessel lid and the accompanying control system automatically regulates the combustion process, seamlessly switching between semi-flameless and completely flameless combustion modes when the temperature rises well above the self-ignition point of the fuels.
Benefits:
- Predictable, consistent ladle temperature
- Maximum refractory lifetime through controlled combustion
- Greater energy efficiency and lower emissions
- Reduced number of ladles in operation
- Increased ladle lining lifetime has also been documented
Features:
- Integrated burner pilot and UV cell
- Leak testing for safety
- Simpler installation vs. air/fuel systems with recuperative/regenerative technologies
- Flow trains for fuel and oxygen
- Seamless switching between semi-flameless and flameless combustion
- Variable combustion ratio for modern refractory materials
- Continuous power and ratio control
- Programmable heating curves for drying and reheating
- App for remote monitoring and scheduling (for iPhones, iPads and other mobile devices)
- Integration of advanced burner control system into existing process landscape
