An Investigation of Evaluation Possibilities of Muş-Elmakaya Lignite

Abstract

Lignite is the most important source of energy in Turkey. Turkish lignite is 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, evaluation possibilities of Muş-Elmakaya lignite are investigated. For this purpose, experimental studies were performed with lignite samples taken from a lignite field in Muş-Elmakaya, Turkey. First, petrographic analysis, major element analysis, and proximate analysis of lignite samples were done. Afterwards, washability properties of lignite samples were determined. Evaluation of the washability properties was done by using washability number, calorific value, and sulfur content of the clean coal obtained from float-sink tests and the obtained results were presented.
