Combustion analysis of the oil furnace. Part 1, draft and smoke

18/11/2013 · This is the first in the series on combustion analysis for the oil furnace. It covers checking draft and setting smoke with the smoke pump. This video is part of the heating and cooling series of training videos made to accompany my websites: and to pass on what I have learned in many years of service and repair.

Carbon dioxide concentration in air coal combustion may vary from 12 to 15 vol%, in natural gas combustion from 3 to 10 vol%, while in fuel oil and biomass from 3 to 8 vol% . Post Combustion capture of flue gas streams at atmospheric pressure can be achieved by several physical and chemical separation methods, such as absorption, membranes, adsorption and cryogenic processes.

Why do we need a draft regulator? | Fuel Oil News

Draft regulators or barometric dampers are devices used to regulate the draft on oil-fired furnaces, boilers, and water heaters. Yes, even water heaters! I cant tell you how many times I have seen water heaters installed without a draft regulator installed, and a stack temperature over 900° or 1,000° F, and a draft over the fire that (as we used to say) would suck the chrome off a bumper.

Typically, when a -.005 to -.02 WC is measured over the fire, stack draft will be in the -.02 to -.04 WC range for gas fired power burners and -.04 to -.05 for oil fired burners. Stack draft has been commonly used to set up barometric controls and evaluate draft conditions, however, it does not necessarily guarantee correct over fire

Typically for a natural gas boiler oxygen readings may be in the range 3% to 5%, for an oil boiler 5% to 8% and for a coal fired boiler 8% to 10%. The efficiency of modern condensing gas boiler can be over 100% as heat is extracted from the incoming air. A traditional brick built coal fired boiler may only be 50% efficient.

Carbon dioxide. This is a byproduct of combustion and also displayed as a percent of flue gas volume. If you measure only carbon dioxide without considering the oxygen, carbon monoxide could be present in the flue gases. You could have a good efficiency with acceptable CO2 levels and spewing carbon monoxide up the flue.

Boiler/Burner Combustion Air Supply Requirements and Maintenance

A periodic boiler flue-gas analysis is the best indicator that an adequate supply of combustion air exists. This, and any necessary burner adjustments, should be performed by a trained technician with the proper equipment to measure the amount of excess oxygen and/or carbon dioxide and ppm of carbon monoxide.

Thus, if you calculate a stoichiometric methane combustion with air, the actual (wet) concentrations of CO2 and H2O in the flue gas will be 9.5 vol.-% CO2 and 19 vol.-% H2O, while the dry value for the CO2 concentration will be 11.73 vol.-%. The latter value is the one you need to compare with measured data.
