Which of the following is NOT a part of coal handling and coal preparation system in thermal power plant?

  • A.Ball mill
  • B.Crusher
  • C.Separator
  • D.Chimney

Answer: D

The chimney is not a part of the coal handling and preparation system in a thermal power plant. It belongs to the draught and flue gas system, and it carries the gases away at a height.

A ball mill (to grind coal), a crusher (to break lumps) and a separator (to remove iron and sort the coal) are all parts of the handling and preparation system. So the fourth option is the answer.
