When conducting a trial burn, it is necessary to make a number of measurements to adequately define the performance of the incinerator. In addition to flue gas emissions for particulate matter, HCl, and selected organics, it is also necessary to measure selected organics in the waste feed, incinerator operating temperature, stack gas volume flow, waste feed rate, and many other important parameters. A relatively small, but important segment of this trial burn sampling and analysis universe is addressed in the paper. The sampling and analysis procedures receiving the most attention until recently have been those for organic compounds. The knowledge base and availability of detailed procedures is still expanding. Recently, concerns about metals emissions have caused further research into sampling technology in that area. Accordingly, the principal sampling and related analytical methods to be discussed will be Method 0010, Method 0030, and the new Multiple Metals Train.
