In this work, the elemental analysis results such as carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and sulfur (S) were used for calculated higher heating values (HHVs) of 26 lignite samples from different areas of Turkey. The lignite samples have been tested with particle size of 0-0.05 mm. The HHVs of 26 lignite samples obtained from different Turkish sources were experimentally determined and can be calculated from the equation-based modeling. The HHVs (MJ/kg) of the lignite samples as a function of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), and sulfur (S) was calculated from the following equation: [image omitted] of which the correlation coefficiens for the equation was 0.9891. HHVs calculated from the equation showed mean deviation of +0.1.
