Next, the gas and water mixture enter the pump. The pump contains no valves or packing and will handle the dirtiest of samples without any detrimental effect
Exiting the pump under positive pressure, the sample mixture is forced through a mixer which contains a series of baffles which function to thoroughly scrub the sample gas.
At the next stage of conditioning, the sample solution enters a separa- tor where water is gravitated to drainage. The scrubbed flue gas sample then exits the separator through a sample outlet and enters a
The sample gas stream, having passed the final filtration trap, flows into a tee. Here, the stream is divided with most of the sample gas being vented to atmosphere, while the balance is routed to the oxygen analyzer section. Total flow rate is approximately 20 to 30 SCFH. A back pressure control valve is adjusted to permit proper flow past the oxygen analyzer sensor where the percentage of oxygen concentration in the flue gas sample is determined and displayed on the oxygen analyzer meter.
Following oxygen analysis, the sample passes to the combustible analysis section.
