Challenges faced during implementation of a compressed air energy savings project on a gold mine
(2014)Demand side management (DSM) initiatives have been introduced by Eskom to reduce the deficit between the electricity generation capacity and the electricity usage within the country. DSM projects enable Eskom to reduce ... -
Compressed air energy savings on an iron production plant
(North-West University (South Africa) , Potchefstroom Campus, 2016)In the past several decades, energy efficiency has become increasingly important. A large driver behind this is reducing greenhouse gases that are caused by the combustion of fossil fuels. Most electricity generated in ... -
Developing a dynamic control system for mine compressed air networks
(IEEE, 2014)Mines in general, make use of compressed air systems for daily operational activities. Compressed air on mines is traditionally distributed via compressed air ring networks where multiple shafts are supplied with compressed ... -
Energy efficiency opportunities in mine compressed air systems
(North-West University, 2009)Demand Side Management (DSM) is one of the most viable and sustainable short term methods to address the shortfall in electricity generation in South Africa. This is because DSM projects can be implemented relatively ... -
Expanding compressed air demand side management through selective level control
(North-West University (South Africa)., 2022)Compressed air is a resource which is used across the deep-level mining industry for a variety of purposes throughout the 24-hour mining cycle. It has been noted that compressed air is a particularly inefficient source ... -
Modernising underground compressed air DSM projects to reduce operating costs
(IEEE, 2014)Compressed air is an energy intensive utility that is frequently used in the deep level mining industry. Most compressed air networks are designed to ensure ample compressed air supply to consumers. This has created the ... -
Practical considerations in energy efficient compressor set-point control strategies
(IEEE, 2014)Compressed air supply and demand strategies have received significant attention since integrated demand management was initiated by Eskom. Due to the expensive nature of this vastly utilised energy carrier, every increase ... -
Practical low-cost method to sustain mine compressed air savings
(North-West University (South Africa), 2019)The future of the South African mining industry is uncertain as a result of declining ore grades, reduced gold production and increasing operational costs. However, the industry remains a significant contributor to the ... -
Simplified high-level investigation methodology for energy saving initiatives on deep-level mine compressed air systems
(North-West University, 2018)Marginal deep-level mines in South Africa are struggling due to current economic conditions. Reducing operating cost on these marginal mines will increase their profitability. Electricity is one of the fastest growing ...
