Oxidizing reactions as energy source are discussed, based on theoretic
al considerations and operational results, The energy yield for post-c
ombustion is evaluated with data from four furnaces in operation, The
energy yield from post-combustion ranges from 4 to 2 kWh per Nm(3) of
oxygen, representing a range of 4 to 18 Nm(3) oxygen injected for post
-combustion.
