Abstract:
A sampling system for separating gaseous samples from a gas stream containing particulate matter and transporting the gaseous samples to a location outside of the flowing gas stream comprises an inertial filter mounted on the end of a hollow probe, the inertial filter positioned within the flowing gaseous stream. The inertial filter comprises a filter media mounted within a tube such that a portion of the particulate-containing gaseous steam flows through an annular space between the filter media and the tube wall, the gas to be sampled passes through the filter media into an inner space and the filtered gas is then delivered through the hollow probe to analytical devices external to the space containing the flowing gas stream, such as a flue stack.
