Future of lignite resources: a life cycle analysis ...

Sep 23, 2016  Lignite is divided into fuel lignite (use for fuel) and raw lignite (use for drying) with a ratio of about 1:12, and the hot flue gas generated by fuel lignite is used to dry raw lignite. The entire drying and compression process is a single process with only one product, i.e., lignite briquette.

Lignite - Wikipedia

Lignite is brownish-black in color and has a carbon content of 60-70 percent on a dry ash-free basis. However, its inherent moisture content is sometimes as high as 75 percent and its ash content ranges from 6–19 percent, compared with 6–12 percent for bituminous coal. As a result, its carbon content on the as-received basis (i.e., containing both inherent moisture and mineral matter) is ...
