Flue gas carbon dioxide and oxygen - Ian Braithwaite, BSc

In residential furnaces, optimum fuel-air ratio results in the oxygen level being reduced from 21% (fresh air) to between 8.5-10% oxygen by volume after combustion. To test the oxygen level, a tool called a combustion analyzer is used to measures the amount of oxygen remaining in the flue exhaust gas.

Combustion Oxygen Measurement Calls for a | Power Engineering

Optimizing air intake for boiler operation requires continuous measurement of the oxygen concentration in the flue gas. The typical package boiler is a water tube boiler or flue and smoke tube boiler with a capacity of 5 to 20 t/h (average steam generation capacity). The most widely used fuels are heavy oil, light oil, kerosene, and gas.

Why Oxygen Levels Matter in High Efficiency Boilers

Oxygen: 100 x 5/92 = 5.4% . So, my flue gas analyser would actually measure 5.4% oxygen and display this and 8.7% carbon dioxide. No more calculations will be done here: an exercise for the enthusiastic student is to put the numbers into a spreadsheet and produce a graph like the one shown here. Modern boilers have their combustion settings adjusted for particular values of carbon dioxide.

Flue gas - Wikipedia

May 01, 2017 · During the running of utility boiler, the flue gas oxygen content is one of the most important factors that affects boiler efficiency, and it affects each other with other thermal economic parameters such as flue gas temperature, unburned carbon in fly ash and slag and coal consumption of power supply. So it's a key parameter to optimize the combustion process of fuel in utility boiler through combustion
