Top 10 Questions for Coal Pulverizing Operator Interview

1. Explain the process of coal pulverization in a coal-fired power plant?

Coal pulverization is the process of grinding coal into a fine powder. This powder is then used as fuel in a coal-fired power plant. The process of coal pulverization involves several steps:

• The coal is first crushed into smaller pieces.
• The crushed coal is then fed into a pulverizer, which grinds the coal into a fine powder.
• The pulverized coal is then transported to the boiler, where it is burned to produce heat.

2. What are the different types of coal pulverizers?

Ball mill pulverizer

• A ball mill pulverizer consists of a cylindrical shell that is partially filled with steel balls.
• The coal is fed into the mill, and the balls crush the coal into a fine powder.

Roller mill pulverizer

• A roller mill pulverizer consists of two or more rollers that rotate against a stationary grinding plate.
• The coal is fed into the mill, and the rollers crush the coal into a fine powder.

3. What are the factors that affect the efficiency of a coal pulverizer?

• The type of coal being pulverized
