how to measure the boiler flue gas oxygen content

CHAPTER 3 COMBUSTION CALCULATION

Equally, Oxygen (O2) levels should be in the region of 3-5% for gas appliances and 5 - 8% for oil & solid fuel appliances - Any other levels suggests an inefficient use of energy,wasting fuel and money, or a potentially unsafe situation where too much CO is created through oxygen deficiency. Flue Temperatures for gas appliances should be less than 200 degrees centigrade or less than 300 degrees centigrade

Flue gas carbon dioxide and oxygen - Ian Braithwaite, BSc

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.

Measurement of Oxygen Concentration in Package Boiler Flue

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.

Measurement of Oxygen Concentration in Package Boiler Flue

This Oxygen concentration and humidity at high temperatures consists of a ZR22G detector equipped with a long-life and highly reliable zirconia sensor, and a converter ZR802G equipped with digital communication and data log functions. ZR22G and ZR802G can be measured directly and continuously without a sampling device.

Flue Gas Oxygen Measurement - GasLab.com

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. While there are many combustion analyzers on the market, all of them include an oxygen sensor. For example the AlphaSense O2-A2 is a common electrochemical oxygen sensor used in many models of combustion analyzer. The benefit of this sensor is that it is low-cost,
