Level 1Assessment of Uncontrolled Sinter Plant Emissions.

摘要

The report gives results of sampling and analysis of uncontrolled emissions from two sinter plants,to characterize and quantify the particulate,organic,and inorganic species present. One plant used revert (waste products of other steelmaking operations) material (series 1);the other did not (series 2). In both plants,sampling took place in the windbox gas main before the emission control equipment,using EPA Level 1environmental assessment methodology. Samples from the sinter plant not using revert material were delayed in shipment for 2months and,therefore,received a reduced analytical effort. Particulate concentrations of 1405and 804mg/cu m and total organic emissions of 25.66and 4/84mg/cu m were found for series 1and 2,respectively. No known carcinogenic organic compounds were identified. Organics in both cases were largely high molecular weight materials. For series 1,concentrations of the different organic categories were in the same relative proportion as in the process feed sample,despite the fact that about 85% of the feed organic was destroyed. Analyses indicate that 12inorganic components and 5organic categories might exceed Air-Health MATE values if emitted uncontrolled.
