The Spontaneous Combustion Liability of Akcelik Lignite, Tekirdag/Turkey

摘要

In the present work, the spontaneous combustion liability of the lignite samples obtained from Sahinkoy open pit of Akcelik MiningrnCompany in Tekirdag, Turkey was determined. In order to bring out the susceptibility of the coal samples in concern to self-heating, thernmethod of crossing point temperature (CPT) was utilized. The samples were initially minimized to the required amount by cone andrnquartering and then their particle size were reduced under 74 μm by the use of jaw crusher and ball mill respectively. During thernexperimental works, 35 g of coal samples were exposed to the oxidation under the airflow rate of 100 cc/m for a total of 6 CPT tests.rnFor the disclosure of the risk indices of spontaneous combustion inclination belonging to the coal samples exercised throughout thernexperimental works, an empirical formulae revealed by Feng, Chakravorty and Cochrane was employed.
