LIGNITE COAL
Lignite, also known as brown coal, is a soft, brown sedimentary rock that is the lowest grade of coal. It is formed from naturally compressed peat and has a high moisture content, low carbon content (about 22-25%), and a lower heating value compared to other types of coal. Its main use is in power plants for electricity generation.
Primary Uses
Electricity Generation :
The vast majority (around 79%) of mined lignite is burned in thermal power plants to generate electricity
Synthetic Natural Gas and Liquid Fuels :
Its high volatile matter makes it easier to convert into synthetic gases and liquid petroleum products through processes like gasification and liquefaction.
Agriculture :
Lignite or its fly ash can be used as a soil amendment to improve soil quality and suppress plant pests.
Industrial Applications :
It is used in certain industrial heating processes, such as cement and paper production. Amine-treated lignite (ATL) is also used in drilling mud to reduce fluid loss during drilling operations.
Brick Units :
lignite is used in brick units, both as a fuel source for firing the bricks and, more commonly, its ash (lignite fly ash) is used as a raw material in the brick manufacturing process. When the bricks are fired in a kiln, the admixed lignite burns, providing internal heat throughout the brick body. This reduces the amount of external fuel needed for the kiln, leading to energy savings in the manufacturing process.
