| Abstract: | ABSTRACT In this study, the effects of particle size, moisture, briquetting pressure, and preheating temperature were investigated on briquetting without binder of S?rnak Asphaltite, having a particle size of—20 mm, 46.22% ash, 5.83% total sulphur content, and 4900 kcal/kg calorific value. At the end of the briquetting experiments; mechanical strength values of briquettes produced in optimum conditions (particle size, ? 1 mm; moisture, 3.6%; pressing value, 4 t/cm2; amount of lime, 12%) have the properties of first-class briquettes according to Turkish standards. The mechanical strength values of produced briquettes were affected positively in optimum conditions with preheating to 80°C. In combustion experiments using an upper burning stove, the combustion efficiency of briquettes, which contain 50.54% ash, 16.08% fixed carbon, 33.38% volatile matter, and 4.80% total sulphur have been calculated as 60%. During the combustion, sulphur content in smoke gas and particle emissions were determined as 2.34% and 3 mg/m3, respectively. |
