(Test Method)Standard Test Method for Gross Calorific Value of Coal and Coke
Standard Test Method for Gross Calorific Value of Coal and Coke
SIGNIFICANCE AND USE
5.1 The gross calorific value can be used to compute the total calorific content of the quantity of coal or coke represented by the sample for payment purposes.
5.2 The gross calorific value can be used for computing the calorific value versus sulfur content to determine whether the coal meets regulatory requirements for industrial fuels.
5.3 The gross calorific value can be used to evaluate the effectiveness of beneficiation processes.
5.4 The gross calorific value can be required to classify coals according to Classification D388.
SCOPE
1.1 This test method pertains to the determination of the gross calorific value of coal and coke by either an isoperibol or adiabatic bomb calorimeter.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 8.

3. Terminology
3.1 For additional definitions of terms used in this test method, refer to Terminology D121.
3.2 Definitions:
3.2.1 adiabatic calorimeter—a calorimeter that operates in the adiabatic mode and may or may not use a microprocessor. The
initial temperature before initiating the combustion and the final temperatures are recorded by the operator or the microprocessor.
3.2.2 automated calorimeter—a calorimeter which has a microprocessor that takes the thermometric readings and calculates the
Calibration Value and the Heat of Combustion Values.
3.2.3 British thermal unit [Btu]—is the amount of heat required to raise the temperature of one pound - mass [lbm] of liquid
water at one atmosphere pressure one degree Fahrenheit at a stated temperature. The results of combustion calorimetric tests of
fuels for steam power plants may be expressed in terms of the 1956 International Steam Table calorie (I.T. cal) which is defined
by the relation, 1 I.T. cal = 4.1868 J. The Btu used in modern steam tables is defined by the means of the relation, 1 I.T. cal / g
= 1.8 I.T. Btu / lb. Thus, 1 I.T. Btu / lb = 2.326 J / g.
