Abstract

Efforts to improve the performance of the motor fuel is to add a cyclone before the carburetor that functions to increase the homogeneity of the mixture of air and fuel. In this study, conducted aerodynamic testing in line with Internal Flow Double Cyclone skewed Wall (IFC2SW) to be able to know how big the flow characteristics of the velocity field that arises after passing IFC2SW. The main parameters that will be used as an indicator is that the velocity profile obtained from the measurement of total pressure and static pressure in the duct cross section. Results showed that the characteristics of the velocity field after passing IFC2SW evenly along both the center channel and the channel wall.Keywords : Cyclone, Internal Flow Cyclone Double Skewed Wall

Abstract

Nozzle is one of the most critical component in a pressure vessel because of its sensitivity to thermal fatigue. The fatigue life of a top head nozzle of crack gas drier is calculted based on ASME NB—3216.1 module during fluctuative temperature cycle. The life of ten locations at the nozzle are caculated using two dimensions axisymmetric model. ABAQUS and ANSYS are used to analyze thermal fatigue. The life calculation result of the ten locations is infinite.Keywords : nozzle, thermal fatigue, ASME

Abstract

Fossil fuel reserves are depleting to be anticipated by looking for alternative energy sources. Alternative energy that many developed and researched today is agricultural waste biomass fuel is formed into briquettes. In this research, briquettes are made from dregs the pith of sago in the four of form, namely : cylinders, blocks, cubes and prisms, with and without adhesive sago starch with the presentation of 5% and 10%.This research aimed to determine the effect form briquettes on the combustion rate and determine the physical properties of briquettes without carbonization process, with or without the addition of sago starch as an adhesive which include moisture content, ash content, volatile matter, fixed carbon and heating value.The results research that the form of briquettes affects the combustion rate where the fastest combustion speed was on briquettes form beams, cube and Prism. Percentage adhesive of sago starch affects the early combustion time where time is needed to ignite the briquettes greatest for percentage 10% and the lowest adhesive for briquettes without adhesives. Adhesive sago starch is also very influential on the moisture content, ash content, volatile substances, fixed carbon and heating value. Adhesive sago starch is also very influential on the moisture content, ash content, volatile matter, fixed carbon and heating value. The addition of adhesive sago starch lower heating value.Keywords: Briquettes, sago, Physical Properties, Combustion.
