Gas Detection
Gas Engine Protector Never Sleeps

by a fast-changing gas mix. Gas thresholds are set at three percent maximum for O2 with three levels for methane of warning at 55 percent, maximum of 60 percent and a sitevariable minimum of 30-40 percent. When
reached the LFG engine is automatically shutdown and gas diverted to flare on site.
Viridor Whiteheadâs LFG engineâs protection is now totally dependent on its Geotech static gas analyser set automatically to sample, analyse and report 8640 times a day, every day. The readings are data logged and
provide gas output statistics available via secure Internet access for Viridor at any location where there is an Internet connection.
Describing the installation, power plant supervisor, Mark Woollams said, âProtection 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.â
To ensure gas analyser accuracy an autocalibration system routinely purges and calibrates the equipment. The data from each auto-calibration is also collected by the data loggers enabling a full verification audit trail for all gas analysis readings and calibrations.
