Coal briquettes and their binders were always tested from the view of resistivity to transportation, loading and storage by measuring the abrasion index and strength to crushing. The binders used in coal briquetting also affect to the combustion properties of coal. Tuncbilek lignite sample and Polymer Laboratories PL-TGA 1500 thermogravimetric analyzer (TG/DTG) for the determination of the combustion properties of the sample were used throughout the research. Molasses, CMC, Sulphide Liquor, Corn Starch, Crude oil, Lime and Sodium Silicate were used as binders with a ratio of 10% by weight. Molasses and CMC decreased the activation energies of the samples and the residue at the end of the combustion. Crude oil, Sulphide Liquor and Corn Starch increased the calorific value of the samples, however they also increased the activation energies. II was observed that Lime and Sodium Silicate were the most disadvantageous binders by not only increasing the activation energies and residue at the end of combustion, but also decreasing the calorific values of the samples.
