Effect of different binders on the combustion properties of lignite -: Part I.: Effect on thermal properties

Coal briquettes and the binders were 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 the combustion properties of the coal. Combustion properties of the Tuncbilek lignite and different binders were analysed by thermogravimetric (TG/DTG) methods. Molasses, carboxyl methylcellulose (CMC), sulphide liquor, heavy crude oil, sodium silicate, cornstarch, lime, peridur, and bentonite, cement poly(vinyl acetate) were used as binders. It was observed that molasses and CMC decreased the residue content at the end of the combustion period, whereas, heavy crude oil, sulphide liquor and corn starch increased the calorific values of the samples.
