Description:
The PM10 ambient air particulate concentration standardhas created a need for updating measurement methods for PM10 emissions (nominally 10 um aerodynamic diameter and smaller) from stationary sources. Condensable emissions can be a significant portion of stack emissions. Further, since these substances primarily condense to particles less than 10 um in diameter, they form a greater percentage of the PM10 fraction than of the total particulate matter emissions. Therefore, the need arises for developing a source test method which includes the condensable component of emissions. A review of possible techniques was conducted to determine current methodology and to make recommendations for research. Research is recommended on two approaches. One is a dilution method which simulates plume formation by mixing stack gases with conditioned ambient air and the other is an adaptation of utilizing the Method 5 back-half catch.
