Properties of lignite from the Konya-Ilgin-Çavuşçu deposit and its potential use in a future power plant (Turkey)

The Konya-Ilgin-Çavuşçu lignite coalfield is located in the central part of Turkey. This coalfield has been mined in an open-pit manner by private companies. There is a single mined coal seam, the thickness of which varies between 1.10-37.15 m. A total of sixty five boreholes have been drilled in the area toward assessing the reserves. Confirmed and extractable reserves have been calculated by the polygon and isopach methods, depending on the boreholes drilled at different times. There is enough coal in the Ilgin-Çavuşçu coalfield to fuel a thermal power plant. © Czech Geological Survey

Concentration of major and trace elements in the miocene lignite from the Canakkale-Can coalfield

This study focuses on major and trace element concentrations of three lignite samples, of which two are from the working lignite seam and one from a feed coal to an thermal power plant. The anakkale-an lignite deposit is currently being mined by open-cast mining methods despite its high sulfur content. The production lignites are mainly consumed by an fluidized-bed thermal power plant with 2 160 MW capacity and less domestic heating and industrial factories around an. Major oxide compositions of the coal ash samples imply that the more abundant oxides are SiO2 and Al2O3 and less CaO and Fe2O3. Trace element concentrations in the samples on whole-coal basis show that three samples analyzed were enriched in V, and also concentrations of B, Sc, Sn, Th, Tl, and U in one sample that exceed the range values of most world coals

Importance of lignite deposits in Turkey's energy policy and measures taken for environmental protection

Turkey has about 8.4 Gt of lignite reserves, of which 3.9 Gt are exploitable. The majority of Turkish lignite deposits are worked in open-pit mines. Most of the known lignite deposits are of low calorific value and have high contents of ash, moisture and total sulphur. Almost approximately 97 % of the total reserves have calorific values below 3000 kcal/kg. The lignites having low calorific values are generally consumed by power plants. Those with relatively high calorific values are exploited for household and industry in the country. Lignite reserves which are important for energy demand of Turkey have been examined in this article
