Emerson Flue Gas Oxygen Analyzer Optimizes Combustion Efficiency

Emerson Process Management has enhanced the Rosemount Analytical 6888 In Situ Flue Gas O2 Analyzer with new diagnostics that help maintain optimum oxygen levels in flue gases, thereby optimizing the combustion efficiency of large boilers and industrial furnaces.

FF1409 EmersonProdThe 6888 incorporates a "calibration recommended" diagnostic with gas-switching solenoids embedded within the probe electronics, making automatic calibration easier than ever, and maintaining the best accuracy possible. The embedded diagnostic reduces the cost of providing and installing a separate solenoid box, and also minimizes the effort to wire and pipe between the probe and electronics. Additionally, the calibration recommended diagnostic removes the need to conduct calibrations on a schedule. The new analyzer also includes a "plugged diffuser/filter" diagnostic for applications that have fly ash or other particulate entrained in the flue gases, which further reduces personnel time and maintenance as well as helping to ensure accuracy.

Another new feature of the 6888 is a variable insertion option, which permits ideal placement of the probe into the flue gas duct. With standard length probes from 18" (.5m) to 12' (3.65m) in horizontal or vertical installation, the probe can be adjusted at any time on-line to characterize stratification across large ducts.
