Combustion analysis of the gas furnace
As with oil furnaces, the proper mixture of fuel and air are necessary for combustion to be complete and as much heat as possible is released.
Also, incomplete combustion can cause the release of carbon monoxide or other toxic gasses.
The procedure is to use an analyzer to determine the amount of carbon dioxide, the amount the amount of unburned oxygen, the temperature of the gasses and the amount of carbon monoxide in the flue gas. By comparing the percentages of the gasses, combustion efficiency can be determined.
Tools like shown in the above pics are used for the analysis.
Many years ago, furnaces could be fired with wood, coal, oil or gas.
When gas was used, combustion analysis was of the flue gas was necessary to assure proper combustion. Large gas burners used on commercial or industrial boilers still use combustion analysis to set their burners.
Beginning around 1960, the gas designed furnace was developed.
These units did not require analysis. If the gas pressure was set to factory specs, all that was required was to manually adjust the primary air at the burners.
This does not mean that there is no value to combustion analysis on these units.
A carbon monoxide detector can sometimes detect a cracked heat exchanger.
The analysis can be useful when you can't find out why there is a burner problem.
