Predrying coal – technologies and economicsSep 24, 2014· Predrying coal – technologies and economics. Lignite is an important fuel for power generation in many parts of the world. The major issue is that the high moisture content of lignite results in low thermal efficiencies and high CO2 emissions of lignitefired power plants.
Drying Technologies of Lignite Coals – IspatGuruJul 20, 2018· The drying or dewatering of the lignite coals decreases the problems caused by the high moisture content. This reduces the burden on the coal handling system, conveyers and crushers. Also, since dried coal is easier to convey, this reduces maintenance costs and increases availability of the coal handling system.
