Apr 10, 2019  Clean coal is an energy that can generally be used as fuel, the fine coal of bituminous coal is generally used for coking. The main reasons of washing coal are as bellow: 1. Improve coal quality and reduce emissions of coal-fired pollutants. Coal washing can remove 50%-80% of ash and 30%-40% of total sulfur (or 60%~80% of inorganic sulfur) in coal.

Preliminary Study of Calorific Value Increase on Lignite ...

The size of the coal also affects the calorific value of lignite coal. Four coal sizes applied in the study (80, 64, 16, and 6 mesh), indicates coal size 80 mesh has given the best calorific value improvement. Conversely, the smaller of the coal size, increase biosurfactant absorption. Thus, improve the washing capability of biosurfactants.
