At least at 75° or more moisture and ash can be separated easily but if coal sample is impure or one more element is added in then the temp. rises to 85° or more

Not actual answer
The moisture in coal is an important property which should be frequently analysed and monitored. It can be readily removed by evaporation at room temperature but moisture held within the coal itself, known as inherent moisture is difficult to remove.

Dear Swamini,
● Answer -
Coal sample is heated at 105-110 ℃ temperature for removal of moisture and ash.
● Explaination -
- Coal is the most common form of energy used on industrial scale.
- To remove ash and moisture, coal sample is first heated at 105-110 ℃ in silica crucible.
- Ash & moisture gets removed only pure coal remains in furnace.
- This is then dried, cooled and weight.
Thanks for the question...
