How much CO2 is in a flue gas?
Typical flue gases from natural gas-fired power plants may contain 8-10% CO2, 18-20% H2O, 2-3% O2, and 67-72% N2; typical flue gases from coal-fired boilers may contain 12-14 vol% CO2, 8-10 vol% H2O, 3-5 vol % O2 and 72-77% N2.
How do you calculate the volume of a flue of gas?
As shown in Figure 1.1, the dry stoichiometric flue gas flow rate (m3/s) is obtained by multiplying the heat release (MW) by a fuel factor (m3/MJ).
Is flue gas denser than air?
Combustion of a fuel gas creates a flue gas with higher density than the fuel gas and the combustion air.
What is CO2 density?
1562 kg/m3

How do you separate CO2 from flue gas?
CO2 can be separated from other gases by cooling and condensation. Cryogenic separation is widely used commercially for streams that already have high CO2 concentrations (typically >90%) but it is not used for more dilute CO2 streams.
How do you get CO2 from flue gas?
CO2 can be removed from the flue gas of existing pulverised coal fired power stations by retrofitting a new process which recovers the CO2 as a pure liquid by distillation. The boiler is modified to burn the fuel in a CO2 and Oxygen mixture instead of air.
What is flue gas velocity?
Continuous flow measurement which facilitates stack velocity, volumetric flow and pollutant mass release calculations when linked to gas and dust CEMS.
What is boiler flue gas?
Flue gas refers to a chemical byproduct substance that is generated as a result of a combustion reaction that has escaped through long pipes such as those in boilers, furnaces or steam generators. Flue gas may also be referred to as exhaust gas and may act as a reactor agent for atmospheric corrosion.
What is calculated by flue gas analysis?
3. Which of the following is calculated by flue gas analysis? Explanation: The only practical way for determining the amount of air used in furnace is to analyse the flue gas for the constituents CO2, CO an O2.
What is the percentage of CO2 in flue gas?
Typical flue gases from natural gas-fired power plants may contain 8-10% CO 2, 18-20% H 2 O, 2-3% O 2, and 67-72% N 2; typical flue gases from coal-fired boilers may contain 12-14 vol% CO 2, 8-10 vol% H 2 O, 3-5 vol % O 2 and 72-77% N 2.
What are the main components of the flue gas in pulverised coal combustion?
The main components of the flue gas in pulverised coal combustion for post- combustion capture are CO2, N2, O2and H2O, and air pollutants such as SOx, NOx, particulates, HCl, HF, mercury as well as other contaminants. The most widespread method of post-combustion capture of CO2is by solvent absorption.
Does coal combustion produce more wet flue gas than natural gas?
The data were obtained by stoichiometric calculations. The total amount of wet flue gas generated by coal combustion is only 10 percent higher than the flue gas generated by natural-gas combustion (the ratio for dry flue gas is higher).
What are the flue gases measured in a gas test?
The flue gases analysed will be one or more of carbon dioxide, carbon monoxide and oxygen. If carbon dioxide alone is measured it is possible to draw erroneous conclusions, as the level will peak at stoichiometric and reduce in both the excess air and air deficiency regions.
