Landfill Biogas Sierra Instruments

+

Landfill gas is very humid, at low pressure (20 40 mBarg) and about 4060°C (100F) when it is produced by the landfill. Most companies are interested in measuring the biogas as it leaves the landfill, but this is difficult. Low pressure makes differential pressure (dP) devices like orifice plates unsuitable since dP devices require a fairly large differential pressure to operate. Also, …

The pressure sensor measures the vacuum on the header which, via a programmable logic controller and VFD, controls the frequency and voltage supplied to the motor. This in turn controls the speed at which the blower impeller(s) operate. The VFD can speed up or slow down the blower to maintain a consistent vacuum on the GCS. With such controls, technicians can more …
