Characterization of Long-Term Toxic Emissions from Municipal Sludge Incineration - Project Plans and Status

摘要

Emissions testing is to be conducted on four municipal sludge incinerators over longer periods of time than normal. Three multiple hearths and one fluid bed are to be included and testing is scheduled during April, May, and June 1987. Measurements are planned over the short term under smooth compliance testing type conditions and over longer times in order to include typical varying conditions. Variations that might be encountered include startup, shutdown, temperature excursions, feed rate changes, and downtime during maintenance on part of the dewatering system. Metals and organics are both of interest, including products of incomplete combustion. Closing of material balances is desired where possible. The comparisons between short-term and long-term operation could point the way to more realistic testing and regulating of sludge incineration in the future.
