Paper Title
REDUCING THE NEGATIVE ENVIRONMENTAL EFFECTS OF COAL FIRED POWER PLANT

Abstract
In Turkey, which is dependent on foreign sources in terms of oil, natural gas and hard coal, the reserves of lignite, which is the most important fossil fuel source, are approximately 19.32 billion tons. 79.1 million tons of lignite were consumed in 2022. All of the consumed lignite was produced from domestic sources and 83.5% of this consumed amount was used in electricity production in thermal power plants. 30.9% of our country's electricity production is obtained from coal. Only 14.9% of this is obtained from domestic sources, while the remaining 16% is from imported coal. Despite the high external dependency in energy in Turkey, one of the main reasons why very low amounts of electricity are obtained from domestic lignite is that a significant portion of these reserves are low-rank, have high ash and sulfur content. The average sulfur content is over 2% and the average calorific value is around 1200-1300 kcal/kg. Therefore, the use of these lignitesin energy production without purification causes severe negative effects on the environment. The effective evaluation of Turkish domestic lignite reserves, which have the greatest potential as a primary energy source, is important for the country's economy. However, the low rank, high ash and sulfur content of lignite reserves restrict their use. In this project, to reduce the negative environmental effects of these lignites, the enrichment of low rank, high ash and sulfur lignites is studied by flotation methods.
