  Suggestions regarding moisture and ash content in coal

  Ash content determination in coal relies on weighing, with a high accuracy, about one gram of dry coal in a crucible and putting the sample into a cold furnace. Next, the crucible is heated up to 450–500oC within 1 hour. After 2 hours of heating at this temperature the roasting temperature is increased to 700–750oC. At this temperature the ...
