Determination of Fugitive Coal Dust Emissions from Rotary Railcar Dumping. Volume 2. Appendices A-H

摘要

TRC Environmental Consultants, Inc. conducted 72 field tests to determine particulate emission levels for a rotary railcar coal dumper operated by the Potomac Electric Power Company. Approximately 60 parameters were monitored as part of the testing program. These parameters related to particulate emissions, meteorology, and coal properties. The railcar dumper was situated inside of a shed. No other control devices were in operation during the test program. Emissions were measured at the entrance and exit doorways of the shed using the mass flux technique. Background levels were accounted for using the upwind/downwind technique. The amount of particulate material that deposited within the shed was also recorded. The study resulted in the determination of emission levels that were one to two orders of magnitude less than those cited in the literature. These emission levels were found to correlate the strongest with the moisture content of the coal and whether the coal was washed or unwashed.
