BS EN 14181 calibration at ALSTOM Aghada

Posted on: April 29, 2010

As part of commissioning the new 430MW Combined Cycle Gas Turbine (CCGT) at Aghada, Ireland, Environmental Compliance was awarded the contract to perform the calibration of the newly installed MCERTS SICK MAIHAK MCS 100 E HW multi-gas analyser in accordance with BS EN 14181.

The project comprised of 2 stages, as prescribed in BS EN 14181, the first being a Functional Test audit, the second being parallel measurements using standard reference methods utilising Environmental Compliance’s MCERTS accredited FTIR analyser. The parallel measurements, spread evenly over 4 days, allowed a calibration function to be established for all determinands.

BS EN 14181 stipulates that standby fuels would require either a QAL2 or Annual Surveillance Test (AST), depending upon their usage over the year. As the site is expected to operate on the standby fuel oil for <10% of the time during the year, an AST was undertaken to verify that the calibration function, derived during the QAL2, is also valid for oil firing.
