Because of the heterogeneity of coal, gravimetric feed systems have a number of advantages over volumetric systems when it comes to achieving optimized combustion in pulverized coal fired power plants, with lower emissions. Gravimetric systems are widely used in the USA, volumetric feeders currently predominate in Europe, but with the
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.
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.. 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.
