Combustion

Our solutions for combustion processes

In metal and glass casting and finishing processes, energy consumption, fuel costs and gas emissions present major obstacles to sustainability and productivity. Air Liquide has a wide range of solutions to improve efficiency and profitability.

Combustion at a glance

Oxygen is an important part in the primary smelting process. Air is commonly used as a source of oxygen for combustion to heat industrial furnaces. Oxy-combustion is based on the enrichment of air with pure oxygen to improve the efficiency of the smelting process. By using oxygen instead of air, the nitrogen content is reduced, which does not participate in combustion, and by reducing the nitrogen content, heat losses are reduced, while the temperature and reaction rate are increased. Additionally, with oxy-combustion systems, fuel consumption is significantly reduced, and therefore the generation of carbon dioxide and nitrogen oxide.

Our offer

Air Liquide has developed a range of oxy-fuel technologies that harness the power of pure oxygen instead of air in burners to heat furnaces for superior production efficiency (BoostAL TM ).

We are proficient in oxy-fuel technologies, for example in proprietary burner design and furnace heating modelling. We harness this knowledge and put it to work for our customers through a tailored approach, from conception to commissioning and full operation of their furnaces.

Combustion Applications

Glass Finishing

Glass is a completely recyclable and sustainable material. Due to population and infrastructure growth, the demand for glass is constantly growing. Therefore, the challenge has arisen to increase production efficiency so that the process remains sustainable and productive.

Quality is another key challenge. When newly produced glassware rolls off your production lines, it often has a host of blemishes such as sharp edges, cut marks and others caused by your molds. Now more than ever, manufacturers are looking for reliable processes to mitigate these defects and improve their production performance.

Air Liquide offers solutions for glassware surface reheating and edge melting after the forming process. The technology is designed to erase marks created by the edges of bottle molds or to polish the sharp edges of table glasses. This gives glass products, including fine items such as dinnerware, perfume bottles, and crystal glasses, a smooth, shiny appearance.

Nexelia for Glass Finishing provides an oxy-fuel solution with high-performance equipment where there is no need to waste precious time during the last stage of your process, as a high temperature oxy-flame achieves fast in-line polishing. Simultaneously, quality is significantly increased by reducing the number of defects and rejects, thus increasing the production rate.

Oxy-combustion

Additionally, with oxy-combustion systems, fuel consumption is significantly reduced, and therefore the generation of CO2 and NOx.

Air Liquide's oxy-fuel technologies are well suited for argon oxygen decarburization (AOD) and electric arc furnaces (EAF). Air Liquide supplies oxy-fuel solutions to maximize the productivity of Electric Arc Furnaces (EAF) in steel mills. Oxygen is supplied to increase the heating potential through oxy-fuel burners in the furnace.
