#0183;#32;It''s measured in British thermal units (Btu) or millijoules per kilogram (MJ/kg). A Btu is the amount of heat that will warm approximately gallonsa pound of waterby 1 degree Frenheit at sea level. MJ/kg represents the amount of energy stored in a kilogram. This is an expression of energy density for fuels measured by weight.
Physical Properties of Coal. Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Coal like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it.
Avariety of low rank coals have been treated by mechanical thermal expression (MTE). Under identical conditions, the percentage water 10 removal decreased in proportion to the water content of the raw

The results showed that the clean coal yield after MTET at the 9 MPa and 200#176;C condition was % higher than that of untreated coal under the same flotation conditions. Both hydrophilic oxygen functional groups and porosity of the lignite decreased after MTET, increasing the absorption efficiency of oil collector on the lignite surface and the probability of bubbleparticle attachment.

#0183;#32;Mechanical thermal expression (MTE) was a process developed for the energy efficient dewatering from high moisture content lignite. A significant amount of researches on many different aspects of the MTE process had been carried out by researchers in CRC for Clean Power from Lignite and Monash University in Australia and Dortmund University in Germany [5], [6], [7], [8], [9], [10],
#0183;#32;Mechanical thermal expression (MTE) which combines the benefits of both hydrothermal and press dewatering was developed by Strau#223; et al. . By compressing the lignite at elevated temperatures, the lignite dewaters more quickly and more effectively than at ambient conditions, but also with lower wastewater contamination than for hydrothermal dewatering.
#0183;#32;Mechanical thermal expression (MTE) is a pressure dewatering process, which is carried out at elevated temperatures. The process is being investigated as a means of lowering greenhouse gas emissions from existing lignite fired power stations by reducing the moisture content of lignites.

Mechanical thermal expression (MTE) is a dewatering technology ideally suited for the dewatering of internally porous biomaterials. For such materials, the combined application of temperature and compressive force in the MTE process enhances the collapse of the porous structure, resulting in effective water removal.
