Bituminous. The next stage of coal is hard and a shiny, smooth black color, with a high Btu rating. It also contains a sticky substance known as bitumen, which is used when making asphalt, but this sticky coal makes it tricky to undergo coal drying processes before being burned. Much of this coal is used for energy production as it does not ...

coal drying equipment and impact of fuel moisture on plant performance and emissions are discussed. The improvement in boiler and unit performance, achieved during the test by removing 6 percent of fuel moisture was in the to percent range. This performance improvement is primarily due to a reduction in moisture evaporation loss, lower

With the rising cost of energy and fuel oils, clean coal technologies will continue to play an important role during the transition to a clean energy future. Victorian brown coals have high oxygen and moisture contents and hence low calorific value. This paper presents an alternative non evaporative drying technology for high moisture brown coals based on osmotic dewatering.
