Aluminum Melting

praxair oxygen-enhanced technology for Aluminum Melting

Inject productivity into your operation

Aluminum Melting Flame Praxair has developed and commercialized several proprietary oxygen-injection techniques, oxy-fuel combustion systems, and aluminum melting burners that enhance the productivity and efficiency of aluminum melting furnaces. Oxygen injection increases the heat available in the furnace for melting by reducing the heat loss due to hot nitrogen in the flue gas. Oxy/fuel combustion for secondary aluminum melting provides many benefits compared to conventional air/fuel combustion. These benefits include:

  • Increased flame temperature

  • Increased productivity

  • Reduction in flue gas

  • Fuel savings 

The reduction in the flue gas volume and particulate material entrainment with oxy-fuel combustion greatly reduces the cost and complexity of off-gas cleaning systems.
