Advantages and Disadvantages of Pulverized Coal Firing
Pulverized coal is used in modern thermal power plants. It is a powdered form of coal i.e., coal that is grounded into a dust-like size. The pulverized coal is then conveyed to the furnace by way of a stream of hot air. An important purpose of pulverization is to expose a large surface area to oxygen, thus aiding in the burning …Web
