You are at Linde LienHwa Industrial Gases in Taiwan
Glass Melting

Different technologies are available to suit individual furnace and production conditions.

You can choose among the following:
  • Oxygen enrichment
  • Oxygen lancing
  • Oxyfuel boosting
  • All Oxyfuel

All of these technologies are based on the replacement of air with oxygen. Thanks to the elimination of nitrogen and the higher concentration of oxygen, the flame temperature is increased.

These technologies also improve the effectiveness of the gas jet due to the higher concentrations of carbon dioxide and water in the vicinity of the flame. These gases drastically increase the thermal radiation.

Heating for metal fabrication

Examples of heating include flame straightening, flame hardening, hot forming and heating in conjunction with welding. The flame is used for melting purposes in flame brazing, and for fusing purposes with flame sprayed coatings. With oxyfuel cutting and gouging, the flame heats to ignition temperature in order to start and maintain the cutting process.

Hydrocarbons such as methane, ethylene, acetylene, propane, and propylene or hydrogen are used as fuel gases for flame heating. The flame temperature and intensity depends on the fuel gases used and oxygen mixing ratio. Acetylene and hydrogen flames can be set to a normal or reducing atmosphere whereas all other common fuel gases have an oxidizing flame.
