Performing a Combustion Analysis

Carbon dioxide (CO2) reading: The CO2 level in the flue gas provides an indication of the efficiency of the combustion process. If the production of CO2 is as high as possible with slight excess air (complete combustion), the flue gas heat losses are at their lowest. The CO2 reading is calculated from the O2 reading by the analyzer.

Why Oxygen Levels Matter in High Efficiency Boilers

For every pound of water vapor condensed there is approximately 1,000 BTUs of latent energy. Condensing extracts that latent energy from the combustion exhaust gas and heats the water with it, increasing overall boiler efficiency. High efficiency boilers require combustion gas calibration at start up.

Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the flame temperature and reduce NOx formation.
