Installation Model 76002.5.6 Purging the AnalyzerIn general, purging the analyzer is not required unless one of thefollowing cases apply:• A combustible gas component is contained in sample gas.• Corrosive gas is contained in the atmospheric air at theinstallation site.• The same gas as the sample gas component is contained inthe atmospheric air at the installation site.In the above situations, the inside of analyzer should be purgedwith instrument air or N 2 . Use a purge flow rate of about 1 L/min.Use a filter to remove dust or mist from the purge gas.2.5.7 Sample Gas PressureThe sample gas pressure at the outlet should be atmosphericpressure.2.5.8 Example configuration of gas sampling systemA typical system configuration with five component gas analysisfor monitoring combustion exhaust gas from boiler, refuse incinerator,etc. is shown in Figure 2-8. Contact Teledyne for specific applicationsystem configuration or further information.The system shown is comprised of:• Model 7600—with dual measuring unit option and externalzirconia oxygen sensor.• Gas Extractor—with stainless steel filter of standard mesh 40μm equipped with integral heater.• Mist Filter—to remove condensate, mist and dust from thesample before it enters the analyzer.• Safety Drain Trap—with two compartments for positive andnegative pressure. It monitors and adjusts the sample gaspressure.• Gas Aspirator—to aspirate the sample gas.• Electronic Gas Cooler—used to dry the sample gas to a dewpoint of approximately 2°C (35.6°F).Teledyne Analytical Instruments 30
Infrared Gas AnalyzerInstallation• Solenoid Valve—for introducing calibration gas andOFF/ON flow of sample gas.• Membrane Filter—PTFE filter for rempval of fine dustparticles.• Flowmeter—adjusts and monitors the sample gas flowrate.• Standard Gas—a bank of calibration gases used for settingzero and span of the analyzer for each species monitored.• Zirconia Sensor— an external zirconia sensor is used formeasuring the oxygen concentration in the sample gas. Someinstruments use a built-in paramagnetic oxygen sensorinstead aof an external zirconia sensor.• NO 2 /NO Converter—added to the NO analysis circuit whichuses an efficient catalyst for converting NO 2 to NO foranalysis.Figure 2-8: Five-Component Analysis SystemTeledyne Analytical Instruments 31
