Kömür Bileşenlerinin Kalorifik Değer Üzerindeki Etkisi Üzerine Değerlendirme

Coal quality is generally defined based on the ash contents. It is well known that the calorific value of coal is negatively affected by the increase on ash contents. However, the attitude of calorific value is not only dependent on ash content, it is also controlled by proximate and ultimate coal analysis components such as moisture, volatile matter, fixed carbon, total carbon, hydrogen, nitrogen and sulfur content. In addition, coal petrography is also worth to be counted as a factor controlling the calorific values of coal. In this study the relationships between the factors of proximate and ultimate analysis components and calorific value of coals have been discussed through some known coal examples from Turkey.
