Abstract

It has been known from the previous researchers that the use of the heat radiation reflector can improve the efficiency of the LPG stoves. Based on the radiation theory, the radiation energy is emitted radially in all directions. Therefore, a kind of method to guide the heat radiation is required to minimize the heat losses. One of the method is to add some fins to the reflector in order to capture the potential heat loss from the non-finned reflector. In this work, we use one fin line reflector made from a plate of stainless steel in the shape of cutted-cone. The boiling water test is used to investigate the efficiency of LPG stoves. We find that the efficiency of LPG stoves can be increased by adding one fin line reflector by about 5.21% and 1.75% than that one without reflector and non-finned reflector, respectively. The result of the temperature distribution shows that one fin line reflector enlarges the area of complete combustion.

Abstract

Machining is one of the processes in a manufacturing of a product. Manufacturing design is needed for improving the quality of a product. The desired manufacturing process is the achievement of a product with a smooth level of roughness and a short time. Bracket is one component of a series of machines. Work on bracket using CNC milling and Turning machine. The material used is aluminum alloy 6063. The main variables in this machining process are the speed of feeding, cutting speed and feeding motion. The results achieved in the machining process of this bracket are for the roughness on the surface of the N5 with Ra (ideal) = 0.4 μm of Ra (actual) = 0.410 μm. As for the roughness of N6 with Ra (ideal) = 0,8 μm obtained result Ra (actual) = 0,832 μm and 0,625 μm. Total machining time for one workpiece are 1 hour 57 minutes 25 seconds.
