What is the major air pollutant found in coal?
The major air pollutants found in coal are carbon dioxide and methane.
What is bad air in coal mining?
It is air that is bad
How does the carbon in coal become part of the carbon dioxide in the air?
When coal is burnt the chemical change combines carbon from the coal with oxygen from the air to produce carbon dioxide.
Which substances is obtained by heating coal in absence of air?
When coal is heated in the absence of air, it undergoes a process called destructive distillation or pyrolysis, resulting in the formation of substances such as coal gas, coal tar, and coke.
What is the meaning of adb in coal specification?
ADB stands for Air Dried Basis in coal specification. This term refers to the moisture content of coal after it has been air dried under specific conditions. It is used to standardize coal analysis and compare the energy content of different coal samples.
What element in the air is needed for coal dust to burn?
Oxygen is the element in the air that is needed for coal dust to burn. When coal dust is exposed to oxygen and heat, it can ignite and burn.
When coal is heated in the absence of air what is the gas called?
The gas produced when coal is heated in the absence of air is called coal gas. It is a mixture of various gases such as methane, hydrogen, carbon monoxide, and carbon dioxide.
Why must coal be heated in the absence of air to change into coke?
Coal needs to be heated in the absence of air to turn into coke because oxygen in the air would react with the coal and burn it, preventing the transformation into coke. Heating the coal in the absence of air allows the volatile components to be driven off, leaving behind a more solid and pure carbon structure, which is coke.
What is coal carbonization?
Coal carbonization is a process where coal is heated in the absence of air to produce coke, a fuel used in steel manufacturing and other industrial processes. This process involves the conversion of coal into different byproducts like coke, coal gas, and coal tar. It helps to increase the energy content and purity of coal, making it more suitable for certain applications.
What mineral found in coal?
Sulfur is a common mineral found in coal. Its presence in coal can lead to sulfur dioxide emissions when the coal is burned, contributing to air pollution.
What are some good and bad about coal?
The good about coal is that it is a source of energy while the bad is that it pollutes air.
What is the advantage and disadvantage of Coal?
Advantage: Coal is abundant and relatively cheap to mine and use for energy production. Disadvantage: Burning coal releases harmful pollutants into the air, contributing to air pollution and climate change.
