Analyser increases oxygen measurement accuracy

Emerson Process Management has introduced AccuMax technology to enhance boiler and furnace efficiency and reduce emissions, by improving oxygen measurement accuracy

A new feature of the Rosemount Analytical X-Stream O2 analyser helps customers maintain accurate oxygen measurements.

With today's sustained fuel price increases, boiler and furnace operators are examining ways to reduce oxygen in their flue gas to achieve higher efficiencies and lower nitrogen oxide and greenhouse gas emissions.

Accurate flue gas oxygen measurements are critical to attaining these goals.

"Numerous variables can create inaccuracies in oxygen measurements resulting in less efficient combustion control and wasted fuel," said Doug Simmers, product manager for Emerson Rosemount Analytical Gas Division: "Extensive testing regarding these variables led to the development of AccuMax technology for the X-Stream O2 analyser, which offers industry leading accuracy and stability".

The performance-enhancing AccuMax technology includes an internal mechanical assembly that stabilises cell temperature, increasing oxygen measurement accuracy.

AccuMax also incorporates a Calibration-Recommended Diagnostic which identifies when the probe requires calibration, eliminating the need to schedule calibrations on a periodic basis.

According to Simmers, "The Calibration-Recommended Diagnostic saves time and calibration gas, and ensures that the operator always has an accurate analyser.

These savings can pay back the analyser purchase price in just a few weeks".
