An Assessment of Malatya-Arguvan Lignite and Southeastern Anatolia Region Lignites (Turkey)

Abstract

Turkish lignites are usually low in heating value and burning characteristic with high sulfur and ash content. They are unable to conform to air protection regulation requirements if burned as mined. Generally, they are used in power plants causing environmental problems. In this study, assessment possibilities of Malatya-Arguvan lignite are investigated and washability properties of Eastern and Southeastern Anatolia region lignites are discussed. For this purpose, experimental studies were performed with lignite samples taken from a lignite field in Malatya-Arguvan, Turkey. First, proximate analysis of lignite samples was made. Afterwards, washability properties of lignite samples were determined. Assessment of the washability properties was made by calculating some of the popular indices, such as index of washability, washability number, and near gravity material index, and the obtained results were presented.
