Abstract :

Investigation of the development and characterization of briquette from sesame stalk and waste paper as binder was examined for production of fuel briquettes. The raw sesame stalk was characterized by the following properties: moisture content (3.63%), fixed carbon (17.50%), volatile matter (72.82%) and ash content (6.05%). Briquettes were produced by mixing carbonized sesame stalk with waste paper in weight percentage ratios of 90:10, 80:20, 70:30, 60:40 and 50:50 at three different average particle sizes of sesame stalk (1, 3 and 5mm).From the experiment, the results of all sesame stalk briquettes fall in the range of bulk density (526.21-535.62Kg/m3), shatter resistance (88.02-89.07%), volatile matter (64.01-69.20%), ash content (10.46-14.25%) and calorific value (25.167-28.00MJ/Kg). The combination of 5mm average particle size of sesame stalk and 10% waste paper percentage gave the optimal volatile matter of 69.20%, ash content 10.46% and calorific value 28.00MJ/kg. From the results of the present study, it may be concluded that calorific values of briquettes obtained were enough to produce energy content for combustion and due to this about 40% consumption of petcoke of Dashen cement factory with sesame stalk fuel briquette can reduce about 2,410 tons of CO2 per year emitted from combustion of fossil fuel petcoke and that can affects the environment.
