Experimental Study of Magnesium Production with Laser for Clean Energy Cycle

Nowadays the demand for energy increased rapidly duo to escalating population and global technological development. Consequently, the focus on non-conventional energy sources is increasing rapidly due to change in climates and unhealthy environment caused by fossil fuels. Solar energy is vital to fulfill this growing need of clean energy. The performance of the photovoltaic (PV) technology used for capturing sun’s radiation is directly affected by solar irradiation. The optimum performance of the PV systems would be possible if the solar panel is always orientated towards the direction of maximum radiations of sun. Hence, in order improve the performance of the PV, tracking of maximum radiation of the sun is extremely important. In this experimental study, solar tracking is done using a single axis solar sun tracker which not only provides accurate but also cost efficient solar sun tracking in comparison with an existing stationary system of same capacity. The results show that a single axis solar tracking systems have generated approximately 28.3% more compared to static systems and is also found to be more economic than a solar tracking system which uses microcontroller.

To improve the using efficiency of clean energy, in this investigation, three wind-heating devices, nonlayered-stirring heating device, layered-stirring heating device and layered extruded stirring heating device, were designed, fabricated and tested. The performance of these three devices was investigated experimentally. Results show that, under the experimental conditions, the layered extruded stirring heating device is the most efficient, and its heating efficiency reaches 46.4%. Then, the computational fluid dynamics (CFD) models were established base on these three devices. The comparative analysis of the simulation and experimental results, both obtained consistent heating law. This suggests that the use of the software CFD simulating the stirring heating device is feasible.

Slag Performance

An experimental study has been performed on the desulfurization performance of the original magnesium slag (from the process of magnesium production). The total content of CaO and Ca2SiO4 is near 90% in the slag, but its conversion rate is below to 30% as desulfurizer directly in the experimental conditions. The aim of this paper is to enhance the performance of the slag by the hydration treatment process. In the hydration process, the slag, additives and water are mixed proportionally in slurry, then dehydrated and dried. Compared different slag performance by TGA, the optimal hydration method is found. The results show that a much higher calcium conversion rate (about 40%) of the slag is obtained after the hydration process. By means of XRD, Sorptomtic Instrument and SEM, the related parameters of the original slag and the hydration treated slag are analyzed. It is found that the composition, appearance and surface area changed obviously. The principle is basically studied that the hydration may enhance the desulfurization performance of the slag.
