Measurement of Oxygen Concentration in Package Boiler Flue Gases
09/01/2020 · A Deep Learning Model for Measuring Oxygen Content of Boiler Flue Gas. Abstract: The oxygen content of boiler flue gas is a valid indicator of boiler efficiency and emissions. Measuring the oxygen content of boiler flue gas is time consuming and costly. To overcome the latter shortcomings, a novel deep belief network algorithm based hybrid prediction model for the oxygen content of boiler
01/05/2017 · 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
It should be noted that most boilers require higher flue-gas oxygen content at lower loads. This generally results from the fact that mixing is compromised in the burner at low loads. Additionally flue-gas oxygen content targets will be influenced by additional environmental controls such as nitrogen oxide control.

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. The ZR22G/ZR802G zirconia oxygen analyzer is ideally suited for package boilers thanks to its long service life and low maintenance, and is an effective tool for the reduction of fuel and electric power
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.
The total number of units of flue gas is 79 + 8 + 5 = 92. This allows us to work out the percentages of gases as displayed by the flue gas analyser. Carbon dioxide: 100 x 8/92 = 8.7%. Oxygen: 100 x 5/92 = 5.4%. So, my flue gas analyser would actually measure
