This standard specifies the determination method of the re-absorption moisture of improved coal, including the definition of terms, method summary, reagents, instruments and equipment, coal sample preparation, test steps, result statement, method precision and test report, etc. It is suitable for the determination of the re-absorption moisture of low-rank coal after upgrading. Methods The re-absorption moisture is calculated according to the measured value of the coal sample mass and total moisture under specific temperature and humidity conditions, and the re-absorption time of the coal sample - Linear dispersion of the re-absorption moisture is used to reflect the water re-absorption situation.
