Subject content and scope of application
This standard specifies the classification and naming of coal according to the range of received base lower calorific value (Qe.ar). This standard applies to power coal and civilian coal. 2 Classification of coal calorific value
Coal calorific value is classified according to the following table
Name
Low calorific value coal
Medium-low calorific value coal
Medium calorific value coal
Medium-high calorific value coal
High calorific value coal
Extra-high calorific value coal
Note: When the coalfield geological exploration system is classified according to calorific value, the total moisture (M) can be used for calculation. Additional remarks:
This standard is proposed by the Ministry of Coal Industry of the People's Republic of China. This standard is under the jurisdiction of the National Coal Standardization Technical Committee. This standard was drafted and interpreted by the Beijing Coal Chemistry Research Institute of the China Coal Research Institute. The main drafters of this standard are Chen Wenmin, Liu Shuyun and Wang Zhiling. Approved by the State Bureau of Technical Supervision on September 24, 1994 18
