Abstract: An off-gas analyzer for analyzing H2O vapor, CO, O2, CO2 and/or H2 in a furnace gas stream is fluidically coupled to a gas extraction probe. The analyzer includes an optical measurement cell having multiple sampling chambers, optically coupled to a laser. The analyzer measuring cell is housed within a heated cabinet having a heater operable to heat the interior thereof so as to maintain the extracted gas sample therein at a temperature about the condensation point of water. The analyzer allows for the analysis of the gas water vapour of wet off-gas samples.

Abstract: A system for measuring water and/or gaseous phase content of high temperature process gases includes a probe for gas sample extraction and cooling temperatures below those which probe filter or gas analyzer components degrade. A heated gas extraction tube provided within the probe interior operates to maintain the thermal stability of the cooled gas sample to preserve chemical integrity.

Abstract: An optically based combustion off-gas stream velocity sensor assembly is provided for detecting in real-time off-gas flow velocity and/or volume as it moves through a flue duct. The sensor assembly includes two paired coherent light emitters and optic sensors, positioned in a spaced orientation in the flow path direction. The light emitter/optic sensor pairs operate to emit and detect across the off-gas stream coherent light beam energy having a wavelength component corresponding to an absorption profile of an off-gas species component. The detection of non-absorbed portions of the emitted beam is used to identify and detect the movement of a flow species signature at different locations along the flue duct.
