Rosemount Analytical 6888 In Situ Flue Gas O2 Analyzer

Wednesday, 20 August, 2014 | Supplied by: Emerson Automation Solutions



The Rosemount Analytical 6888 In Situ Flue Gas O2 Analyzer has been enhanced with new diagnostics that help maintain optimum oxygen levels in flue gases, thereby optimising the combustion efficiency of large boilers and industrial furnaces. The enhancements help decrease maintenance requirements and improve measurement accuracy.

The product incorporates a ‘calibration-recommended’ diagnostic with gas-switching solenoids embedded within the probe electronics, making automatic calibration easier. The embedded diagnostic reduces the cost of providing and installing a separate solenoid box, and also reduces 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 analyser also includes a ‘plugged diffuser/filter’ diagnostic for applications that have fly ash or other particulate entrained in the flue gases.

Another feature is a variable insertion option, which permits ideal placement of the probe into the flue gas duct. With standard length probes from 0.5 m to 3.65 m in horizontal or vertical installation, the probe can be adjusted at any time online to characterise stratification across large ducts.

Easy to use and integrate, the product is fully field repairable. All active components can be replaced, including the diffuser/filter, sensing cell, heater and thermocouple and all electronics cards. The device offers HART and Foundation fieldbus digital communications and can be configured with the optional Smart Wireless THUM adapter for wireless operation.
