This involves the simultaneous milling and drying of raw coal immediately before combustion in a beatertype mill, aerated by the hot flue gas drawn off at 900 1000°C from the upper levels of the furnace chamber. Such predrying requires a boiler substantially larger to cope with the large quantity of evaporated water.

Bituminous. The next stage of coal is hard and a shiny, smooth black color, with a high Btu rating. It also contains a sticky substance known as bitumen, which is used when making asphalt, but this sticky coal makes it tricky to undergo coal drying processes before being burned. Much of this coal is used for energy production as it does not ...

Fig. 1 illustrates the primary components at WAC in a process flow diagram. The plant design is based on the Shell Coal Gasification Process (SCGP) in which pulverized fuel mix is converted to synthesis gas (syngas) under substoichiometric conditions in a dry feed slagging entrained flow gasifier at elevated temperatures between 1500 and 1800 °C.. The gas is subsequently cooled for cleaning ...
The high moisture content results in higher CO 2 emissions per unit of energy produced and is responsible for high capital and transport costs as well as other technical problems such as reduction in coal friability and difficulties in its blending and pneumatic transportation.
