Gross Calorific Value in Coal using AC600

<p>The gross calorific value of coal is a critical parameter for assessing fuel quality, determining total energy content, and assigning classification. It also supports calculations for sulfur load, regulatory fuel compliance, and material balances in industrial boiler systems.</p> <p>Using the LECO AC600, this application note guides you through coal sample preparation, execution of ASTM D5865 methodology, and the key method parameters—including calibration with benzoic acid, sulfur correction procedures, and automated measurement. Whether you're evaluating bituminous, high-volatile, or low‐volatile coals, the AC600 offers a streamlined and standardized workflow for gross calorific value determination.</p>
