Applications of Lignite Grinding Machines in Power Generation
Power generation is one of the largest and most important applications of lignite, and lignite grinding machines play a vital role in this process. The quality and fineness of the ground lignite powder directly affect the efficiency and environmental performance of lignite - fired power plants.
In lignite - fired power plants, the primary method of converting lignite's chemical energy into electrical energy is through combustion. Lignite grinding machines are used to reduce lignite into fine powders before it is fed into the boiler. The finer the lignite powder, the larger the surface area available for combustion.
This increased surface area allows for more efficient and complete combustion of the lignite, resulting in higher heat release and improved power generation efficiency. When lignite is ground into a fine powder, it mixes more thoroughly with the combustion air in the boiler, ensuring that all the combustible components of the lignite are oxidized, which maximizes the energy extraction from the fuel.

Modern lignite - fired power plants often use advanced combustion technologies, such as pulverized - coal - fired (PC) boilers and circulating fluidized - bed (CFB) boilers. In PC boilers, the finely ground lignite powder is injected into the boiler furnace along with preheated air. The high - velocity air - powder mixture is ignited, and the lignite burns rapidly in suspension. The fineness of the lignite powder is critical in PC boilers as it affects the ignition and combustion stability. If the lignite powder is too coarse, i
