Flue Gas Analyzer

Emerson has launched the latest solution for combustion flue gas analysis, the Rosemount Analytical 6888 in-situ oxygen analyzer. The 6888 analyzer provides accurate measurement of oxygen remaining in flue gases coming from combustion processes such as boilers, incinerators, kilns, process heaters, and industrial heating furnaces. By maintaining the ideal level of oxygen in the flue gases, optimal efficiency is achieved and the lowest levels of NOx, CO, and CO2 are produced. The in-situ design of the 6888 places a zirconium oxide sensing element at the end of a probe, which can be inserted directly into a flue gas stream. Probe lengths are available from 18 inches to 12 feet, and a slip-mounting option enables mounting a long probe at any insertion depth. Signal conditioning electronics reside in the head of each probe, eliminating the need for expensive signal cable.

The 6888 is fully field-repairable. All active components can be replaced, including the diffuser/filter, sensing cell, heater and thermocouple, and all electronics cards. A dual-channel operator interface unit provides an easy-to-use method of setup, calibration, and failure diagnostics.
