Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Flyash is a fine powdery residue obtained from the combustion of pulverized coal in thermal power plants.
Step 1: In thermal power plants, coal is burned to produce heat energy.
Step 2: This heat energy is used to convert water into steam, and steam is used to generate electricity.
Step 3: During combustion of pulverized coal, fine ash particles are carried along with flue gases.
Step 4: These fine ash particles are collected using electrostatic precipitators or other collection systems.
Step 5: This collected fine ash is called: \[ \text{Flyash} \] Therefore, the waste/by-product obtained during burning of pulverized coal is: \[ \boxed{\text{Flyash}} \]
