Show The metals data from the Ogden test show that a substantial amount of metals are captured by the bed material, and that metals emissions are minimal except for zinc and copper. These are the test data summaries from the California full-scale hazardous waste combustors. All data were taken under more or less steady state conditions. Several conclusions may be made from this data. CONCLUSIONS Data were presented from full-scale hazardous waste combustors in California. The following conclusions may be drawn from this data: * Data from California facilities show that a Destruction and Removal Efficiency (DRE) of 99.99%, HCI removal of 99%, and particulate emissions of 0.08 grains/DSCF can be achieved if there is adequate residence time, combustion temperature, excess oxygen and adequate air pollution control equipment. * For a range of facilities, factors that influence combustion (temperature, residence time, stoichiometry) do not significantly influence DRE at the levels of concern (above 99.99%). * For a range of facilities, factors that indicate combustion efficiency (levels of CO and Total Unburned Hydrocarbons In the stack gas) may correlate with DRE, and with each other. * For some isolated facilities, data may correlate between factors that influence or indicate good combustion and with the measure of combustion efficiency, DRE.
