Flue gas analysers usually display a CO/CO2 ratio. This shows the ratio of carbon monoxide and carbon dioxide in the exit flue (chimney) of the appliance. Generally when this level is below 0.004 the boiler is considered to be running efficiently. For oil or coal fired appliances the CO should not be above 200ppm.
How does a gas analyser work?
An infrared gas analyzer measures trace gases by determining the absorption of an emitted infrared light source through a certain air sample. Air with much of a certain gas will absorb more of a certain frequency, allowing the sensor to report a high concentration of the corresponding molecule.
Which is the best flue gas analyser?
- Testo 310 Flue Gas Analyser.
- Testo 327-1 Flue Gas Analyser.
- Anton Flue Gas Analyser — eVo2Kit3 Sprint.
- Kane Flue Gas Analyser (455)
- Regin Probe Regxa1.
What is analyser calibration?
Calibration of an analyzer or instrument establishes the quantitative relationship between an actual value of a standard, be it a pollutant concentration, a temperature, or a mass value (in ppm, oC or Φg, etc.) and the analyzer's response (chart recorder reading, output volts, digital output, etc.).
What are the different types of gas analyzers?
- Pellistor/Catalytic Bead (CB) Industrial Gas Analyzers.
- Point/Non-Dispersive Infrared (PIR/NDIR) Industrial Gas Analyzers.
- Tunable/Enhanced Laser Diode Spectroscopy (TLDS/ELDS) Industrial Gas Analyzers.
- Electrochemical (EC) Industrial Gas Analyzers.
Do I need a flue gas analyser?
A flue gas analyser (FGA) is a vital tool for any Gas Safe Register, OFTEC or HETAS qualified engineer when installing, commissioning, fault finding, repairing or servicing heating appliances. On modern gas appliances you can not see the burner flame.
What is the ideal CO2 content of flue gas?
Carbon dioxide - CO2 - is a combustion product and the content of CO2 in a flue gas is an important indication of the combustion efficiency. Optimal content of carbon dioxide CO2 after combustion is approximately 10% for natural gas and approximately 13% for lighter oils.
What are good combustion analyzer readings?
This is a byproduct of combustion and also displayed as a percent of flue gas volume. You could have a good efficiency with acceptable CO2 levels and spewing carbon monoxide up the flue. Many burner manufacturers look for a reading of between 8 1/2% to 10% in the flue gas.
What should the CO CO2 ratio be?
According to the literature, the ratio of carbon dioxide and carbon mono- xide (CO2/CO) for a transformer with a healthy cellulose insulation system should be between 3 and 11.
