Drying Technologies of Lignite Coals – IspatGuru

Methods of the drying of the lignite coals can be broadly divided into two groups. In the first group, the method of drying is known as evaporative drying. In the evaporative drying of the coal, the heat is provided to remove the water from the coal particle. The drying medium can be air, flue gas, or superheated steam.

Report on comparison among current industrial scale lignite drying

The cost of O&M for the dryers at Coal Creek Station were estimated at 0.35 $ per wet tonne of lignite processed or 350,000 $/y for a 113 t/h dryer. But other expenses due to fuel, auxiliary power consumption and other O&M costs were reduced through the use of pre-drying at both units by more than $20 million annually [32] .

Introduction. Lignite is considered to be a lowest-rank coal with high moisture and volatile content [1]. A very large proportion of the 'non-caloric content' – water, which is sometimes as high as 60%, absorbs a great amount of heat to evaporate during the combustion process, leading to a lower caloric value of lignite than that of the black …
