Why is coal pulverized?

Coal is pulverized primarily to improve its combustion efficiency. Here's why:

Increased Surface Area: Pulverizing coal turns it into a fine powder, greatly increasing its surface area. This allows it to burn more quickly and completely than larger chunks.

Improved Combustion: Fine coal powder mixes better with air, making combustion more efficient. This helps generate more heat energy from the same amount of coal.

Consistent Burning: Pulverized coal provides a more uniform and controllable burn, which is essential in power plants to maintain steady steam production and electricity generation.

Better Heat Transfer: In boilers, finely ground coal allows better heat transfer to water, improving the efficiency of steam production.

Reduced Waste: Complete combustion reduces the amount of unburned carbon in ash, leading to less waste and lower emissions.
