What is it for?
Our proven and patented combustion technologies based on enriching air with pure oxygen will support your needs for making furnaces in the glass and metal industries more energy and cost efficient while also reducing pollutants.
Oxy-combustion at a glance
Air is the most common oxidizing agent in most industrial processes. Combustion occurs due to the reaction of oxygen and combustible molecules like fuel or natural gases. The process of enriching air with pure oxygen is oxy-combustion. This is done to reduce fuel consumption and combined with complete removal of nitrogen from the air, the reduction is more effective. It also helps reduce carbon dioxide and nitrogen oxide emissions that are harmful to humans and the environment.
Several methods enrich air with oxygen and generate optimum heat transfers to the molten product:
- Adding oxygen to air before injection into the furnace
- Direct Oxygen injection into the furnace using lances
- Using oxy-fuel burners for distribution and injection of pure oxygen and fuel
In metallurgy, oxygen is used as a main gas in many applications such as the manufacture of nickel, zinc, steel, copper and aluminium. As a strategic partner for several global metallurgy companies, we offer two ways of supplying our gases to our customers - Pipeline and packed offers. Transportation of gas via pipeline is used when large volumes of gas is required. This is done to negate the environmental impacts of overland shipping as a secure option.
BOOSTAL is our performance enhancement solutions to help companies which require lower volumes of gas. It consists of oxygen, and a full range of advanced technologies for non-ferrous metals, foundries and steel. Our on-site experts l help determine how BOOSTAL solutions can minimise environmental impacts.
Our exceptional R&D Team has developed Nexelia and ALGASS for oxy-combustion in glass making. It includes oxygen delivery, patented burners and additional value-added services.
Gases used for Oxy-combustion
Gas applications under Oxy-combustion
Oxygen enrichment for debottleneckingWe offer Oxynator, our gas-gas mixing device using cross-flow radial injection. This reduces the mixing distance and prevents high oxygen concentrations near air inlet pipe walls.
Oxygen enrichment of recovery boilersRecovery boiler capacity limits pulp production. Air Liquide with JANSSEN, has developed an enrichment technology for oxygen combustion that allows you to increase capacity safely by 10 to 20%.
Oxy BoostingPure oxygen combustion through Oxy Boosting is done by introducing a glass furnace to boost productivity and extend the furnace's lifetime before refurbishment.
Full oxygen glass fusionAir Liquide introduced the HEATOX technology to the market for the preheating of oxygen and fuel gas. This technology generates increased energy efficiency and helps position oxy-combustion as the benchmark technology for glass melting.
Oxygen FeedersThe glass, once produced in the melting furnace, is conveyed to the forming machines by distribution channels called “feeders”. The molten glass is maintained at temperature by Air Liquide’s burners supplied with gas and air at ambient temperature.
Reburning and Polishing of surfacesAir Liquide supplies oxy-natural based gas and oxy-hydrogen based combustion technologies to polish the product surface and remove the defaults present in glass.
Combustion (heating)To support combustion applications such as ladle heating and billet/slab reheating, we offer oxygen as well as related equipment and services.
Ladle metallurgy furnaceWe supply argon and nitrogen for the ladle metallurgy furnace to stir and refine the melted steel. We help the refinement of melted steel in the ladle metallurgy furnace by supplying Argon and Nitrogen.
