New Rosemount Analytical 6888A O2 Combustion Analyzer Improves Boiler Efficiency and Burner Optimization – Key Components of the New EPA MACT/GACT Rule Compliance.
The EPA boiler MACT/GACT rule compliance date for area source (GACT) boilers is here (April 2014). Many companies have delayed implementing upgrades to controls due to the EPA delay in issuing their final ruling. Although thousands of boilers will not be impacted by these rules, many will and they include biomass fueled boilers for the first time.
Rosemount Analytical’s new 6888A in-situ oxygen analyzer can help run your process more efficiently by utilizing their advanced zirconium oxide cell technology for your boiler or your process heater. The zirconium oxide cell was developed by Westinghouse which later became Rosemount Analytical and is the most durable and reliable cell for O2 measurement in industry today.
A Calibration Recommended Diagnostic
The measurement of cell resistance is the major indicator of cell health in the 6888 and this relates strongly to overall accuracy. The 6888A used in conjunction with the Xi Enhanced Interface electronics provides a calibration recommended diagnostic which could be a visual indication from the Xi, or a relay output to the DCS. If the 6888 is connected to an optional automatic calibration system, the relay can also trigger a calibration. An operator can also check cell impedance by the 4-20mA signal wires via HART protocol and may be displayed through a hand-held communicator.
Unnecessary Calibrations also Mean Saving Money
With the new MACT/GACT rules many companies will now only be required to perform a general tune-up of their existing boiler(s). The calibration recommended diagnostic of the Rosemount Analytical 6888 with Xi Enhanced Interface electronics can reduce the amount of time normally associated with performing routine inspections and/or calibrations. Unnecessary calibrations also mean saving money on required calibration gases which can be costly, not to mention the cost of the instrument technician’s time to perform the task. And now the 6888 analyzer comes with an integral automatic calibration option (available with the Xi electronics) for a completely automatic calibration sequence.
