Abstract

Differential Scanning Calorimetric (DSC) applications in coal sciences have expanded rapidly. Various researchers observed that some of the methods to determine spontaneous heating are time consuming, tedious and do not give reproducible results. DSC instruments are usually employed under identical experimental conditions to track the reaction type (i.e., endothermic or exothermic), to calculate kinetics and heat flow rates. Application of DSC for determination of spontaneous heating of coal and suitability in this area is described.
