Trial Burns

Trial burns provide regulatory agencies with the data to issue operating permits. Consequently, trial runs are directed to show that plants achieve the RCRA limits under the desired operating conditions. These RCRA limits are:

A destruction and removal efficiency (DRE) of greater than 99.99% for each of subject principal organic hazardous constituents (POHCs). (Note: the Toxic Substance Control Act [TSCA] requires that incinerators burning PCB and dioxin-containing waste achieve 99.9999% DRE.)

A particulate emission of less than 180 mg per dry standard cu meter (0.08 grains/dry ft) of stack gas (corrected to 7% O2)

Hydrogen chloride (HCl) emissions less than 4 lb/hr (2.4 kg/hr) or greater than 99% removal efficiency

Trial burns test the plant's operating conditions and ability to meet the three RCRA limits. The EPA recommends three or more runs under any one set of conditions, with varying conditions, or with different waste feed characteristics.
