Description:
Measurements of PM-10 particulate matter emissions from stationary sources were performed using two sampling approaches currently under development. PM-10 particulate matter is defined as all particles nominally 10 micrometers aerodynamic diameter and smaller. Aerodynamic inertial particle sizing devices are used in both approaches. The emission gas recycle (EGR) approach used new instrumentation and, as the duct sampling nozzle flow rate was adjusted to remain isokinetic, conditioned recycled emission gas was adjusted coincidentally and added prior to the sizing device: the combined recycle and sample flow at all sampling points in the traverses was the constant required by the sizing device. This satisfied the previous conflict of varying isokinetic flow and constant sizing device flow. The simulated Method 5 (SIM-5) approach used existing instrumentation and a new sampling protocol. Both approaches use multiple points in the sampling plane. EGR and SIM-5 compare favorably with each other and with the reference measurements at the sites.
