What are Pulverizers in Power Plant?

These are used to reduce solid fuels, primarily coal, to fine particles before combustion. This increases the surface area, resulting in more efficient and thorough burning.

Types of Pulverizers

There are three types of pulverizers –

1. Ball and Tube Mills: Pulverizes coal using steel balls and revolving tubes.
2. Vertical Roller Mills: Large rollers crush coal against a spinning table.
3. Impact Mills: Uses hammers to grind coal into a fine powder.

Advantages

Here are some advantages of this machine –

• Improves combustion efficiency.
• Allows for greater control over combustion temperature and emissions.
• Enables the use of low-grade coals.

Applications

Here are some important applications of this machine –

• Used in power plants for coal fired boilers.
• Used in industrial processes necessitate fine coal powder.
