Emissions Assessment of Conventional Stationary Combustion Systems. Volume I. Gas-and Oil-fired Residential Heating Sources.

摘要

Emissions from gas-and oil-fired residential heating sources were assessed through a critical examination of existing emissions data,followed by the conduct of a phased measurement program to fill gaps in the emissions data base. Initially,five gas-fired and five oil-fired residential sources were selected for testing. Mass emission rates of criteria pollutants,trace elements,and organics,including polycyclic organic matter (POM),were determined. Subsequent evaluation of the test program led to a decision to conduct additional tests at one gas-fired and two oil-fired sites. The principal objective of this second test program was to determine the effect of burner on/off cycle on emissions. Particulate sulfate, SO2,and SO3emission data were also obtained at the oil-fired sites. The results of the emissions assessment indicate that residential sources are of potential significance based on multiple source severity factors calculated for an array of houses burning gas or oil. Pollutants for which multiple source severity factors exceed 0.05,the level which may be potentially significant,are NOx from gas-fired sources and SO3,NOx,and Ni from oil-fired sources.
