Advantages of Oxy-gas technology
and Saving energy

The Oxy-gas technology in Distributor and Forehearth reduce energy consumption till 60% and 80% NOx emission compare with Air-Gas technology.

Comparison data hypothesis: Traditional heating premix air/gas zone , 40 burners , 20 each side. Nozzle diameter 6.5 mm, manifold pressure max 20 mbar, natural gas flow for each burner 0.5 Nmc/h. Zone length approx. 2300 mm (skimmer block not included).

Combustion Skids Sketch


Glass Service Oxy-gas burners are a specially design for distributor and forehearth. The main features of those are:

Burners could be easy remove from operational position are reinstall by the calibrate hole.

The correct alignment from the burner block and the burner nozzle is recommended for the correct functionality.

Burners Software
Modelling Design

Burners are design with large use of CDF software mathematic modelling.

By the Math modelling the flame length and shape as well all the functionality parameter are simulate.

The special burners nozzle design include the oxy cleaning technology.
Low valve oxy flow surrounds the burner nozzle and does no allow contact between the combustion residual and the nozzle steel.

This technology remove the carbon deposit on the nozzle.

Burner block design

Burner block is an important part of the technology. The burner block design by Glass Service have a special dimensioning match correctly with the flame shape.

Oxy-Hydrogen Combustion

The oxy-gas skids can be easily applied to reduce emissions by substituting natural gas with hydrogen. Glass Service has already tested the low-power hydrogen-oxygen burner successfully for distributor and forehearth applications.

The natural gas skid technology, applied with thermal mass flow transmitters and flow control valves, is also suitable for hydrogen use.

Glass Service has already designed hydrogen combustion technology skids and solved the leakage issues related to materials, fittings, and equipment, making them ready for hydrogen use.

Not only can hydrogen alone fuel the combustion skids, but in the Green Transition, a blend of natural gas and hydrogen can also be applied.

The oxy-gas combustion technology in distributor and forehearth applications will be the first step towards achieving green hydrogen-oxygen combustion with zero CO2 emissions.

Forehearth and Refractories

The refractory design for the use of oxy-gas combustion technology in distributor and forehearth applications requires special attention to both the material and the shape of the upper structure. 

Glass Service’s experience and design are supported by CFD mathematical modeling of the upper structure and burner blocks.

 Detailed engineering and CFD mathematical modeling were applied to analyze the interaction between the flame and burner blocks, as well as the interaction between the flame and the refractories of the upper structure.

The design takes into account:
