The Gas Engine Protector that never sleeps

Rapid changes in landfill gas quality can damage the engines it powers. To keep watch, Viridor has installed static automatic gas analysis and reporting equipment supplied by Geotech at its Whitehead landfill site near Manchester.

Every ten seconds the equipment measures gas concentrations and outputs the data. Control circuits receive the data and are set to shut down the engine before any damage could occur.

Viridor Whiteheads LFG engine`s protection is now totally dependent on its Geotech equipment. Describing the installation, power plant supervisor, Mark Woollams said, "Protection of our LFG engines is now totally dependent on the static gas analyser. We ran a pilot and are confident we can depend on it totally to protect our engines from damage."

To ensure gas analyser accuracy an auto-calibration system routinely purges and calibrates the equipment. The data from the auto- calibration is also collected by the data loggers enabling a full verification audit trail.
