20.1 Combustion Using Oxygen-Enriched Air
Progress in combustion technologies with fossil
fuel made possible use of oxygen for combustion in
industrial processes, reducing drastically CO

and
NO

emissions as well as allowing for higher pro-
ductivity at highest possible level of product quality.

Since the economy of oxyfuel combustion is depen-
dent on the cost of oxygen, the availability of low-
cost oxygen is critical to the application economy as
well. Development of lower-cost oxygen separation
techniques allows at present use of oxidizer with
almost 100% content of oxygen.

It is known that rising oxygen concentration in the
oxidizer ...
