Coal System. Coal received from the mines is stored in the coal yard adjacent to the power plant. It is then conveyed on a daily basis to the boiler and stored in a ‘Coal Silo’. ‘Coal feeders’ continuously feed the required amount of coal to the ‘Coal Pulverisers’. Coal Pulverisers grind the coal to a very fine powder to make it
A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.
