Environmental impact of an industrial compressed air system with a solar powered compressor in South Africa
Almost 14% of the electricity generated by the national energy supplier (Eskom) in South Africa is sold directly to the mining sector and almost 20% is utilized directly by the compressed air systems of the mining sector. ...
Thermal and efficiency analysis of a single phase induction motor with Peltier devices
We present the results obtained from the thermal and efficiency analysis of a single phase induction motor with Peltier devices. A single phase induction motor is completely simulated in SolidWorks® and Matlab® Simulink®. ...
Design of an intelligent controller for a renewable energy efficient bulk storage tank
The national electricity supplier in South Africa is experiencing difficulty in providing the required electricity, due to compliance with environmental regulations and the continuous price increase of commercial fuels. ...
Efficiency analysis of an induction motor with field oriented control at a hot rolling mill
(Academic Journals, 2012)
In this paper, the efficiency analysis of an induction motor with field-oriented control (FOC) at a hot rolling mill in South Africa is presented. It is shown that the energy consumption of an induction motor at a hot ...
Air drying of fine coal in a fluidized bed
The demand for energy has continued to rise worldwide in line with population growth. The majority of South Africa’s electricity is supplied by coal-fired power stations. The amount of fine coal (-2 mm) generated at coal ...
Active surface area approximation in a lead-acid cell for optimal performance in renewable energy systems
In a renewable energy system, lead-acid batteries are required to last as long as possible whilst providing deep discharges and are usually charged in an intermittent manner. This type of operation is severely detrimental ...
