Matimba Power Station
Matimba Power Station close to Ellisras, Limpopo Province, South Africa, is a dry-cooled coal-fired power plant operated by Eskom. Power generation The station consists of six 665 MW units with a total installed capacity of 3,990 MW. Turbine Maximum Continuous Rating is 35.60%. The power station was commissioned between 1988 and 1993. Matimba is the largest direct dry-cooled power station in the world. The use of dry-cooling technology has considerably reduced water consumption at the plant relative to those using wet-cooling systems. Matimba is fueled by the open cast Grootegeluk coal mine on the Waterberg Coalfield with about 14.6 million tons of coal a year via a conveyor system. The mine is also contracted to supply the new Medupi Power Station.

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. Some iron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megawatt

Ellisras
Lephalale (formerly Ellisras) is a coal mining town in the Limpopo province of South Africa immediately east of the Waterberg Coalfield. The town was established as Ellisras in 1960 and named after Patrick Ellis and Piet Erasmus who settled on a farm there in the 1930s. In 2002, Ellisras was renamed Lephalale by the provincial government of Limpopo, after the main river that crosses the municipality. Lephalale is divided into three main subsections, Ellisras, Onverwacht and Marapong. Lephalale is derived from the setswana language meaning "to flow". History 1550 to 1750 Late Iron Age cattle posts belonging to the Letsibogo ceramic facies have been found in the area. Some rock engravings at Nelsonkop have been recorded. 1930s The name Ellisras origins from a combination of the surnames of Patric Ellis and Piet Erasmus who settled in the 1930s on the farm Waterkloof 502LQ. Since the opening of the main route between Vaalwater and Stockpoort during 1929 a railway bus stop developed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal-fired Power Plant
A coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity. Worldwide, there are about 8,500 coal-fired power stations totaling over 2,000 gigawatts capacity. They generate about a third of the world's electricity, but cause many illnesses and early deaths, mainly from air pollution. A coal-fired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coal-fired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators. Thus chemical energy stored in coal is converted successively into thermal energy, mechanical energy and, finally, electrical energy. Coal-fired power stations emit over 10 Gt of carbon dioxide each year, about one fifth of world greenhouse gas emissions, so are the single largest cause of climate change. More than half of all the coal-fired electricity in the world is generated in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maximum Continuous Rating
In electrical engineering and mechanical engineering, the power rating of equipment is the highest power input allowed to flow through particular equipment. According to the particular discipline, the term ''power'' may refer to electrical or mechanical power. A power rating can also involve average and maximum power, which may vary depending on the kind of equipment and its application. Power rating limits are usually set as a guideline by the manufacturers, protecting the equipment and simplifying the design of larger systems, by providing a level of operation under which the equipment will not be damaged while allowing for a certain safety margin. Equipment types Dissipative equipment In equipment which primarily dissipate electric power or convert it into mechanical power, such as resistors, and speakers, the power rating given is usually the maximum power that can be safely dissipated by the equipment. The usual reason for this limit is heat, although in certain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grootegeluk Coal Mine
The Grootegeluk Coal Mine is an open cast coal mine within the Waterberg Coalfield of the Limpopo province of South Africa. It is operated by Exxaro. The mine is from Lephalale, and employs 2,000 people. Discovery In 1920, coal was found in the Ellisras Basin, but at first little was done to investigate the size of the resource. Between 1941 and 1952, 143 diamond-drill holes and two prospecting shafts were sunk to obtain a geological map of the Waterberg coalfield. In 1957 Iscor (later unbundled into Kumba Resources and Mittal Steel South Africa) bought surface rights on six farms located in the coalfield. In 1973 Iscor began detailed exploration of the deposits below the farms to determine the quality and quantity of coal. In 1979 Iscor obtained the mining leases on the farms and in 1980 established the Grootegeluk Coal Mine. The mine contains semi-soft coking coal, thermal coal and metallurgical coal. There is estimated to be 2,800 Mt of accessible coal out of a to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lephalale Local Municipality
Lephalale Local Municipality is located in the Waterberg District Municipality of Limpopo province, South Africa. The seat of Lephalale Local Municipality is Lephalale. Politics In the 2004 South African general election, the ANC won with an overwhelming majority of 88% (with 27,299 votes), while the Democratic Alliance (DA) and Freedom Front Plus (FF+, Afrikaans: VF+) only received 7% and 2% respectively. In the 2009 South African general election, the ANC's support fell to 82.0% (24,451 votes), while the DA increased their vote percentage to 8.5% (2,521 votes) and COPE, a newly formed party, gained 5.7% (1,697 votes) of the vote. The Freedom Front Plus, the now 4th largest part, lost some support to 1.61% (480 votes), albeit only 17 fewer votes. In the most recent 2014 South African general election, the ANC once again won overwhelmingly but again lost support, this time earning 73.8%.

Medupi Power Station
Medupi Power Station is a dry-cooled coal-fired power station built by Eskom near Lephalale in Limpopo province, South Africa. The name chosen for the station, Medupi, is a Sepedi word which means "gentle rain". With an installed capacity of 4,764 MW, when fully operational it should be the 8th largest coal-fired power station in the world. Original concept Medupi was conceived as Project Alpha in 2007, with only three units planned to total 2,400 MW and estimated cost of R32 billion. The design was changed at a late stage in 2007 and doubled in size to 4,764 MW. The boilers were envisaged to be supercritical in type, which would make them 38% more effective than other Eskom power stations. A dry cooled system was also intended to use less water than other coal-fired power stations in the fleet. Initial project costing was estimated at R69 billion but that was updated to approximately R80 billion by 2007. Parsons Brinckerhoff was appointed as the project engineer to oversee al ...
