Benefits of oxy-fuel:
- Lower NOx-emissions (up to 80% lower than that of
conventional gas fired furnaces) Lower dust emissions (25%
lower)
- Improved productivity (much less gas-drawn heat is lost up in
furnace stacks)
- Significant improvement in product quality made possible
through improved melter control
- Improvement in energy efficiency

To meet the ever increasing economic challenges and stringent
specifications of the glass industry, Pressure swing adsorption systems
can give the right solution. Use of Oxygen as a fuel gives the glass
industry the much needed alternative to the traditional air-gas burners.
Oxy-gas firing as it is called is one of the best available technology
for reduction in the energy consumption in melting/refining. PSA, VSA or
Cryogenic techniques are generally used for Oxygen-fuel. Cryogenic
techniques are generally used for large scale production while
capacities requiring lower production PSA or VPSA can be used. The
following table displays the energy requirement for producing oxygen
through three different methods.
