Air drying of fine coal in a fluidized bed
(SAIMM, 2015)
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
(IFAC, 2014)
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 ...
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 ...
Thermal and efficiency analysis of a single phase induction motor with Peltier devices
(Emerald, 2012)
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 and heat flow analysis of a commercial energy efficient in-line water heating system
(Emerald, 2014)
In this paper, the authors provide the design, heat flow analysis and pressure analysis of a commercial energy efficient in-line water heating system in South Africa. The designed commercial in-line water heating system ...
Environmental impact of an industrial compressed air system with a solar powered compressor in South Africa
(Sage, 2012)
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. ...
Measurement and verification baseline development and service level adjustments for fridge plant systems
(2009)
In this article the authors provide an overview of a fridge plant system and discuss the data requirements and data selection for baseline development. The baseline development is divided into two scenarios: 1) where ...
Influence of chemical pretreatment on the internal structure and reactivity of Pyrolysis chars produced from sugar cane bagasse
(American Chemical Society, 2012)
The characterization of char obtained from the vacuum pyrolysis (8 kPaabs, 460 °C, 18 °C/min) of sugar cane bagasse followed by steam gasification (60 wt % of steam, 700−900 °C) was studied. The influence of different ...
Environmental impact of an industrial compressed air system for solar power in South Africa
(Multi-Science Publishing, 2012)
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. ...
Design of an intelligent controller for a renewable energy efficient bulk storage tank
(2015)
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. ...
