6. Lower air flow means and a greater tendency to plug with wet coal. 7. Lower air flow leaves more reserve fines in the pulverizer. 8. Also note that lower air flow leaves a deeper bed depth of coal, and thus a higher pulverizer d/p. Keeping the PA flow above minimum line velocity is a very important safety consideration. A

PULVERIZING PLANT / COAL MILL: In modern thermal power generation plants in order to achieve maximum burning efficiency coal is pulverized or ground in order to mix it with the hot air and then feeding to furnace in a stream of hot air. This helps increasing the surface area of the coal to action of oxygen and consequently helping combustion.
