Oxygen Service Offerings for Air-Fuel Furnaces 


Improve your process efficiency with our oxygen service portfolio

Depending on your individual needs and challenges in your glass melting process, industrial gases can contribute significantly and assist you in meeting your individual productivity, emission control, cost and capacity needs. Our oxyfuel combustion portfolio allows for the use of oxygen instead of air. Our experienced team will work with you closely to establish the configuration and supply mode best suited to optimize your individual targets.

Our oxygen service offerings include:

  • Oxygen Enhanced Nitrogen Oxide (NOx) Reduction
  • Zero-port Boost 
  • Reverse Hot Spot Boosting
  • Oxygen Support Service

Oxygen Enhanced Nox Reduction 

Reduce NOx emissions by injecting additional oxygen through high-pressure lances to create a more intense, directional flue gas recirculation effect within your furnace. By doing so, the main burner system produces a diluted, staged combustion process. The fuel dilution leads to a more homogeneous flame and a reduced flame temperature. Flame temperature has a direct impact on NOx levels, lowering emissions significantly and reducing the concentration of hydrocarbon radicals in the furnace. The reduction in hydrocarbons and the improved heat transfer rate also limits NOx formation.

Zero-port Boosting

Using oxyfuel burners to boost the melting capacity of glass furnaces is a proven technology, especially in float furnaces. Furnaces with conventional zero-port oxyfuel technology can boost pull rates, quality levels and furnace life when 10-15% more energy is fed into the furnace in the critical melting area.

Reverse Hot Spot Boosting

Reverse hot spot boosting is beneficial for customers that operate end-port fired regenerative furnaces. And it can be applied to unit melters or recuperative furnaces. Reverse hot spot boosting is compatible with all types of glass. It can help reduce emissions to meet regulation targets and increase furnace pull rates. 

Oxygen Support Service 

We offer a temporary installation designed to ensure continuity of oxygen service during maintenance or repair work. This emergency support service is offered in collaboration with Hotwork International and offers a turnkey option. This is beneficial if you are working with a plugged regenerator or have a leaking recuperative heat recovery system. Oxygen lances and all supporting supply equipment are delivered to your site for the duration of the maintenance work, allowing you to make all necessary repairs without production loss.
