Calculator: Flue Gas Analysis | Thermodyne Boilers

Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel. You can also refer to Thermodyne's Boiler Bible that provides you the general composition of above elements for various …

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, …

Feb 12, 2021 · 2-Calculate the Oxygen level (O2) in flue gas, if excess air is 25%. We have Excess air EA = O2 X 100 / (21-O2) 25 = O2 X 100 / (21-O2) O2 = 4.2%. 3-A Boiler's combustion system requires 5.5 kg of air for burning 1 kg of fuel, then calculate the total air required for complete combustion if its flue gas has 4.1% of O2. We have,

Boiler Efficiency - an overview | ScienceDirect Topics

*As an example: A natural gas fired boiler's flue gas was measured on a wet basis to be 6% O2 and 9% CO2, the corrections would be: % O2, dry basis = %, wet basis x F = 6% x 1.15 = 6.9% % CO2, dry basis = %, wet basis x F = 9% x 1.22 = 10.98% So to determine dry flue gas loss, one needs
