of values are shown in the table: one set for nonhalogenated emission streams and
another set for halogenated emission streams. The combustion temperature and resi-
dence time values listed are conservative and assume adequate mixing of gases in the
incinerator and adequate oxygen in the combustion chamber. The criteria in Table 3 are
not the only conditions required for achieving the specified destruction efficiencies. For
a given destruction efficiency, HAP emission streams may be incinerated at lower tem-
peratures with longer residence times. However, the values provided in Table 3 reflect
temperatures and residence times found in industrial applications. Based on the required
