in the combustion zone of a thermal vapor incinerator, as measured by the temperature
device, is more than 28 oC below the design combustion zone temperature.
All 3-hour periods during which the average Regenerative Thermal Oxidizer (RTO) gas stream
temperature in the combustion zone was below 1350 "F are listed in Table l.
