Investigation of Chemical Properties of Coals on the Tendency of Spontaneous Combustion
Öz
Variations taking place in the chemical specifications (moisture, volatile matter, fixed carbon, calorific
value etc.) of the coal samples with two different particle sizes (35 and 200 mesh) on the effect of the self
ignition liability were examined. The coal samples in concern were preserved under different storing
conditions for a period of 16 weeks. These samples of coal were upheld in different mediums such as
nitrogen tank, deep freezer and oven under the pre-determined constant temperatures of -25, 18 and 30°C
respectively. In order to determine the tendency of spontaneous combustion for the coal samples, the
method of crossing point was used. As a concluding remark, it may be stated that there is an expressive
relation between the liability index (IFCC) and the chemical features of the coal samples.
