Rev. 5 – June 2005

Introduction

The Bacharach Flue-Gas Sample Conditioning System consists of the following components:

Probe with Peltier Cooler

Condensate Pump with Water Trap

Power Supply

The function of this system is to remove water vapor from the flue-gas sample, thus preventing the formation of water droplets inside the probe hose. If water droplets were to form inside the hose, a portion of the gas sample could be absorbed by the water, thus resulting in lower- than-actual readings of NO2 and SO2.

Water vapor is removed from the flue-gas sample by passing the sample through a Peltier Cooler where the sample is chilled, which in turn, causes the water vapor contained in the gas sample to be removed from the sample.

The water that was extracted from the gas sample is then pumped out of the Peltier Cooler and into a water trap.

The now dry, conditioned flue-gas sample is then sent to its associated combustion test equipment for analysis.
