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.

Effect of different binders on the combustion properties of lignite - Part II. Effect on kinetics Altun, Naci Emre; Kök, Mustafa Verşan (2001-10-16) In this research kinetic analysis of the Tuncbilek lignite and its mixture with different binders (molasses, CMC, sulphide liquor, heavy crude oil, sodium silicate, cornstarch, lime, peridur, bentonite, cement and poly(vinyl-acetate)) were analysed by thermogravimetric (TG/DTG) methods. Two different kinetic models (Arrhenius and Coats-Redfern) were used to determine the activation energies of the samples studied. The concept of weighed mean activation energy was applied to determine the overall reactivity ...
Focusing on the combustion properties of binder added coal Hicyilmaz, C; Altun, Naci Emre (2000-10-18) 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, Cru...
Effect of Heating Rate on Thermal Properties and Kinetics of Raw and Cleaned Coal Samples Energy Sources Kök, Mustafa Verşan; Hiçyılmaz, Cahit (2003-01-01)
Effect of particle size on coal pyrolysis Kök, Mustafa Verşan; Karacan, Ozgen; Hicyilmaz, Cahit (1998-01-01) This research comprises the effect of particle size on coal pyrolysis by thermogravimetry (TG/DTG). All the experiments were conducted at non-isothermal heating conditions with a heating rate of 10 degrees C min(-1). in the temperature range of 20-600 degrees C, under nitrogen atmosphere. Different fractions of Cayirhan coal coal showed differences in TG/DTG curves, peak temperatures and residue values. The Arrhenius model is applied to determine the kinetic parameters from TG/DTG curves.
Effect of hydrogen on fatigue behavior of a cadmium coated high strength steel Güleken, Ümran Başak.; Gürbüz, Rıza; Department of Metallurgical and Materials Engineering (2019) C Despite the associated health and safety concerns of Cadmium, this material remains the most commonly used fastener plating material in aerospace applications. The plating operation is done by a well understood and common electrodeposition process. If a cadmium plated part has high strength (1000 MPa and above) then in order to prevent hydrogen embrittlement it must be baked at 191°C for 23 hours, within 2 hours after plating. Yet it has been seen that parts fail due to hydrogen embrittlement during servi...
