A scientific study conducted in a Thermal Power Plant of Afşin-Elbistan has shown that the calorific value of lignite could be increased around 30 percent, which will boost the electricity production capacity of thermal power plants. "Coal Drying and Enrichment Project," which has successfully undergone tests, was jointly prepared by the Ministry of Energy and Natural Resources and the Scientific and Technological Research Council of Turkey (TÜBİTAK). As a part of the study, lignite, or brown coal, firstly goes through a vacuuming process in specially designed boilers. The coal is held in boilers for a while so that its humidity decreases and it could gain high calorific value. The system, which was designed to increase the efficiency of thermal power plants, will allow for a significant increase in electricity production. During an interview, project coordinator Harun Bilirgen said that high humidity and ash content of lignite lowers the coal's calorific value, which poses a trouble for electricity production in thermal power plants. According to Bilgeren, the project, which aims to reduce investment and production costs in energy, would also make a positive contribution to the environment, as it extricates waste and incombustible elements of coal, which lessens pollutant emulsion. Bilirgen also noted that the project has already begun attracting international attention and that they aim to commercialize it.
