Carbon dioxide (CO2), which is the primary greenhouse gas produced from burning fossil fuels (coal, oil, and natural gas)
What are the major by products of the burning of coal?
Coal combustion products (CCP) are fly ash, bottom ash (or boiler slag), and flue-gas desulfurization gypsum. All have three fundamental properties: chemical composition, mineral composition, and particle size distribution.
What is a type of Fibre which is a byproduct of burning coal?
Boiler slag is produced in coal-fired power plants that use wet-bottom boilers. It forms from melted minerals left over from coal combustion. This molten ash is quenched with water to form a solid, black, glassy waste product, called slag. Boiler slag is commonly re-purposed as a useful combustion byproduct.

How dangerous is coal ash?
Coal ash is incredibly dangerous. Short-term exposure can bring irritation of the nose and throat, dizziness, nausea, vomiting, and shortness of breath. Long-term exposure can lead to liver damage, kidney damage, cardiac arrhythmia, and a variety of cancers.
What are two products of burning coal?
Coal combustion products include:
- Fly ash.
- Bottom ash.
- Boiler slag.
- Flue gas desulphurisation gypsum.
- Others types of material such as fluidised bed combustion ash, cenospheres, and scrubber residues.
Which is the best quality of coal and why?
Anthracite is the best quality of coal with least ash content. Anthracite is a hard, compact variety of mineral coal that has a high luster.
What are the effects of burning coal?
Burning coal emits large amounts of carbon dioxide into the atmosphere. Coal is composed almost entirely of carbon, so burning coal unleashes large amounts of carbon dioxide (CO2) into the atmosphere. These emissions have been shown to increase the greenhouse effect in the atmosphere and lead to global warming.
What is the end product of burning coal and where does it go?
When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.
What is the process of burning coal?
Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
What happens when coal reacts with oxygen?
Following chemical reactions takes place in the combustion of coal with the release of heat: C + O2 = CO2 + 8084 Kcal/ Kg of carbon (33940 KJ/Kg) S + O2 = SO2 + 2224 Kcal/Kg of sulfur (9141 KJ/Kg) 2 H2 + O2 = 2 H2O + 28922 Kcal/Kg of hydrogen (142670 KJ/Kg)
Does coal burn with flame?
What is the difference between the burning of a candle and the burning of a fuel like coal? May be you were able to guess right: candle burns with a flame whereas coal does not. Similarly, you will find many other materials burning without a flame.
Can ash cause cancer?
Some of the compounds found in coal ash can cause cancer after continued long-term ingestion and inhalation. When a natural disaster occurs, contamination from coal ash can affect drinking water systems. Public water systems monitor and control for these types of contaminants.
Can coal cause cancer?
Coal miners had significantly higher risk of any cancer, and those with 15+ years of experience had significantly higher risk of lung cancer.
How do you get rid of coal ash?
Some power plants may dispose of it in surface impoundments or in landfills. Others may discharge it into a nearby waterway under the plant’s water discharge permit. Coal ash may also be recycled into products like concrete or wallboard.
