Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed is considered the lowest rank of coal due to its relatively low heat has a carbon content around 25 to 35 percent. It is mined all around the world and is used almost exclusively as a fuel for steamelectric power generation.

The invention relates to a process for processing brown coal for combustion and/or gasification for the purpose of power generation, wherein the brown coal moist from the pit is firstly subjected to preliminary crushing and is subsequently comminuted. The milled coal is then fed to drying in a fluidizedbed dryer. The process is characterized in that the milling apparatus is followed by a

and power generation; and (b) brown coal (subbituminous and lignite), which is used mostly as onsite fuel. Coal has a wide range of moisture (240%), sulfur (%), and ash content (540%). These can affect the value of the coal as a fuel and cause environmental problems in its use. The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat
