622 Oxygen-Enhanced Combustion
As high as 30% of the total mass of waste processed
wassludge. As the ratio of sludge was increased, the
incinerator temperatures decreased (prior to using oxy-
gen enrichment). The two main benets of using oxygen
enrichment in this application were reducing both the
ue gas volume and the unburned carbon.

experimentally measured the effects of
oxygen-enriching the combustion air in an MSW incin-
erator using a thermogravimetric analysis where dif-
ferent atmospheres as a function of temperature with
a constant heating rate were tested.

The waste mass
loss was the primary variable of interest. The ...
