A pulverized coalfired 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.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.

Brown coal is calculated as the sum of subbituminous coal and lignite (Mills, 2011). Subbituminous coal is defined as nonagglomerating coal with a gross calorific value between 4165 and 5700 kcal/kg on moist ash free basis. Lignite is defined as nonagglomerating coal with a gross calorific value on moist ash free basis < 4165 kcal/kg.

· If the coal rakes of are not dispatched immediately, they will have to go on shutdowns, resulting in huge losses to them. On an average, the capacity of a paper mill in UP is 250 tonnes of paper per day which requires one rake of coal in a month. One rake of coal comprises 58 railway wagons carrying anywhere between 5,700 to 4,000 tonnes of coal.
