Why is coal crushed and ground into a fine powder before it is blown into the boiler furnaces?
Coal is crushed and ground into a fine powder before being blown into boiler furnaces primarily to improve combustion efficiency. Here's why:
Increased Surface Area: When coal is ground into a fine powder, its surface area increases dramatically. This allows it to burn much more quickly and completely when mixed with air.
Faster Combustion: Fine coal particles ignite faster than larger chunks. This ensures that the coal burns rapidly and releases heat more efficiently, which is essential for power generation.
Better Temperature Control: Pulverized coal allows for better regulation of furnace temperatures, improving the overall stability and efficiency of the boiler.
Reduced Unburnt Residue: Finely ground coal ensures more complete combustion, which reduces the amount of unburnt carbon in the ash and lowers waste.
Improved Heat Transfer: Complete and efficient burning of pulverized coal produces a consistent and intense flame, which enhances the heat transfer to the boiler tubes, producing steam more effectively.
- In short, pulverizing coal makes the combustion process more efficient, cleaner, and better suited for large-scale power generation.
