Coal conveyor : This is a belt type of arrangement.With this coal is transported from coal storage place in power plant to the place near by boiler. Stoker : The coal which is brought near by boiler has to put in boiler furnance for combustion.This stoker is a mechanical device for feeding coal to a furnace.

The coal slurry was pre-treated with ultrasound for different time intervals (0–180 s) at 25 kHz frequency before flotation. A higher clean coal yield of 67% was attained at a pre-treatment time of 30 s during ultrasonic-assisted flotation, while only 59% clean coal yield was attained during conventional flotation.

In power generation, coal fineness is crucial to maintain flame stability, ensure combustion efficiency, and lower emissions to the environment. In order for the pulverized coal to react effectively in the boiler furnace, the size of coal particles needs to be at least 70% finer than 74 μm.
