ABSTRACT:
A sampling probe for enabling the analysis of gaseous species in a particle-laden flue gas. The sampling probe includes a tube for being inserted into a fluid stream of a particle-laden flue gas substantially perpendicular thereto to cause the fluid stream to separate and flow around the tube. The tube includes a first opening extending along a first axially extending face of the tube downstream relative to the fluid stream such that a portion of the gas enters the tube through the first opening for analysis within the tube, and a second opening extending along a second axially extending face of the tube such that the gas that enters the tube through the first opening exits the tube after analysis into the fluid stream through the second opening to allow analysis of the gas.
