PULVERIZING PLANT In modern thermal power plant, coal is pulverized ground to dust like size and carried to the furnace in a stream of hot air. Pulverizing is a means of exposing a large surface area to the action of oxygen and consequently helping combustion. Pulverizing process consists 3 stages classified as: 1. Feeding 2. Drying 3.
