This paper provides a summary of performance information gained from hazardous waste incineration testing supported by USEPA. The data and results presented focus on twelve (12) environmental performance evaluations conducted on industrial and commercial waste incinerators from 1974-1984. Specific installations tested included liquid injection units, rotary kiln-plus-afterburner furnaces, controlled air units, and the Vulcanus ships which utilize large, unscrubbed liquid injection units. Pumpable liquids, gases, bulk solids, and containized solid-liquid materials were studied. Some units were 'off-site commercial' waste disposal facilities, while others were 'on-site, dedicated' units used for process waste streams or dedicated research installations. These results have shown that well-designed and operated incinerators of typical sizes incinerating a wide variety of organic chemical wastes are capable of meeting current regulatory requirements with some exceptions. Most units investigated were successful in meeting the waste destruction and removal (DRE) requirement, while other requirements such as acid gas (HCl) control and particulate control were occasionally not met with some of the lower technology pollution control systems.
