For every 12 g of carbon burned, 44 g of CO2 are produced
Exactly! This is the fundamental stoichiometric relationship between the combustion of carbon and the production of carbon dioxide (CO2).
In other words:
When 1 atom of carbon (C) reacts with 1 molecule of oxygen (O2), 1 molecule of carbon dioxide (CO2) is formed.
The atomic mass of carbon is 12 g/mol and that of oxygen is 16 g/mol. So the molar mass of CO2 is 12 + 16*2 = 44 g/mol.
This means that for every 12 g of carbon burned, 44 g of CO2 are produced.
This relationship is crucial for understanding the environmental impact of burning fossil fuels. The combustion of coal, oil, and natural gas releases large amounts of CO2 into the atmosphere, contributing to climate change.
To estimate the amount of CO2 produced by a wood stove that consumes 5 kg of wood per hour, we need to make some considerations:
- Composition of wood: Wood is mainly composed of carbon, hydrogen, and oxygen, but its exact composition can vary depending on the type of wood. On average, we can assume that about 50% of the mass of wood is carbon.
- Combustion efficiency: Not all the carbon in the wood is converted into CO2 during combustion. Some may remain as ash or be released as other carbon compounds, such as carbon monoxide (CO). The combustion efficiency depends on the type of stove, temperature, and the amount of oxygen available. We can assume a combustion efficiency of 80%.
Calculation:
- Carbon burned:
- 5 kg of wood * 50% carbon = 2.5 kg of carbon
- Carbon actually converted into CO2:
- 2.5 kg of carbon * 80% efficiency = 2 kg of carbon
- CO2 produced:
- For every 12 g of carbon burned, 44 g of CO2 are produced.
- 2 kg of carbon = 2000 g of carbon
- CO2 produced = (2000 g carbon / 12 g carbon) * 44 g CO2 = 7333.33 g CO2
- CO2 produced = 7.33 kg CO2
So, a wood stove that consumes 5 kg of wood per hour produces about 7.33 kg of CO2 in one hour.
Note: This is an estimate. The actual amount of CO2 produced may vary depending on the factors mentioned above.
An ETC GROUP SRL AH 250 soot remover can reduce 19,243 kg CO2/year
Starting data:
- Wood stove that consumes 5 kg of wood per hour and produces 7.33 kg of CO2 per hour.
- ETC GROUP SRL AH250 soot remover with CO2 reduction efficiency greater than 90%.
- Stove operating for 8 hours a day.
Calculations:
- CO2 reduced per hour: 7.33 kg CO2 * 90% = 6.597 kg CO2
- CO2 reduced per day: 6.597 kg CO2/hour * 8 hours/day = 52.776 kg CO2/day
- CO2 reduced per year: 52.776 kg CO2/day * 365 days/year = 19,243.04 kg CO2/year, rounded to 19,243 kg CO2/year
- CO2 reduced per year by 150 removers: 19,243 kg CO2/year/remover * 150 removers = 2,886,450 kg CO2/year, equal to 2,886.45 tons CO2/year
Additional notes:
- The actual reduction in emissions will also depend on other factors, such as the type of wood used, the combustion efficiency of the stove, and proper maintenance of the remover.
- It is also important to consider other pollutants emitted by wood combustion, such as fine particulate matter (PM10 and PM2.5), which can have significant impacts on human health and the environment.
