Answer»

Correct ANSWER is (a) Pulverized fuel is blown into BOILER room

For explanation: As the casing of the PULVERIZER is under pressure, the leakage of fine coal through the mill casing CAUSES the pulverized fuel to be blown out into the boiler room. The fan used with this mill handles only air THEREFORE the blades erosion by coal particle is eliminated.
