- The most utilization of coal low rank which is the reservoir is abundant is as mixture with other high qualified coal. Then, there is a consideration to use it as fuel at power plants to ensure the world’s energy security. But the inherent moisture contents inside the coal make it become less economical. It has encouraged experts to find the technology to eliminate the moisture contents. This work used a new technology termed as Electromagnetic Dewatering Brown Coal (EDBC). The objective of this work is to study the effects of the strength of electromagnetic field and the temperature for the enhancement of coal product qualities. The indication is there will be the reduction of the inherent moisture contents and the increase of the value heating. The operating conditions are varying the voltage of 0, 4, 8, and 12, and the temperature of 50oC, 60oC, and 70oC. The results of this study show the increasing of heating value from 6,477 kcal/kg to 7,902 kcal/kg and the reduction of the inherent moisture content from 12.09 %(adb) to 2.64 % (adb).
