Calorific Value. The calorific value of coal is measured for almost all coal samples. It is a measure of the heating ability of a coal and is needed to estimate the amount of coal needed to produce a desired amount of heat. Calorific values are also used to define coal rank in low and mediumrank coals below the rank of mediumvolatile ...

India, the world's third largest coal producing country, is expected to maintain strong dependency on coal for the coming few decades. The gross calorific value (GCV) of coal is a key yardstick for many end users purchasing coal from suppliers, as it provides a clear measure of the useful energy content of a coal. Several methods are available to predict GCV using either moisture content and ...

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.
