Medupi Power Station, a Greenfields coalfired plant project located on the west of Lephalale, Limpopo Province, South Africa is currently under construction as part of Eskom's new build programme set to address the electricity demand and supply challenges facing the country.
Figure 12 shows the Rankine cycle on a temperatureentropy diagram for a steam power plant. The solid red lines are for a coalfired power plant; the largedash red lines are for a nuclear plant. The condensed steam is pressurized with a pump from Point 1 to Point 2 and is then heated up in a boiler to reach from Point 2 to Point 3.
The client. In July 2011 when Hitachi Power Africa needed assistance changing the contract structure on the new Medupi power station in Limpopo Province, South Africa, Shanahan Engineering was more than happy to help. Upon completion, the new drycooled coal fired power station with its six boilers each powering an 800 MW turbine producing 4800 ...

The turbines at coal fired power stations are steam driven. The steam is produced using highly purified water demineralised water. This water needs to be recovered due to the high costs involved in its production and also to save water. When the spent steam leaves the turbine it is at a very low pressure and high volume.
Based on regional averages, retrofitting dry cooling systems in lieu of wet cooling towers decreases total annual plant water consumption at existing coal and gasfired power plants by 93% and 100%, respectively, while increasing the levelized cost of electricity generation by approximately 12% and 18%, respectively.
Matimba Power Station is a coalfired power plant that is located in Limpopo. The mine is operated by Eskom, and it is billed to provide 3,990 Mega Watts, which is achieved by six 665 MW units. Matimba Power Station is dry cooled, which means that it does not require so much water to cool it, and also it does not pollute the environment.
The following page lists all coalfired power stations (including lignitefired) that are 3,000 MW or larger current net capacity, which are currently operational or under construction. If a station also has units which do not burn coal, only coalfired capacity is listed. Those power stations that are smaller than 3,000 MW, and those that are only at a planning/proposal stage may be found in ...
ter consumption in Chinese thermal power plant is shown in Table 1. Table 1. Water consumption in Chinese thermal power plant Year 2000 2005 2010 Water consumption, m3/(s⋅GW) In order to control water consuming of coal fired power plant, some provisions of regulations and standards are proposed, as shown in Table 2。 Table 2.
The Medupi Power Station uses direct drycooling systems due to the water scarcity in the Lephalale area and is the fourthlargest coalfired plant and the largest drycooled power station in the world. The power plant incorporates supercritical technology, which is able to operate at higher temperatures than Eskom's earlier generation of ...
Coalfired plant will add to Indian grid by August Singapore relies on fossil fuels more than any other country " study. The Medupi Power Station uses direct drycooling systems due to the water scarcity in the Lephalale area and is the fourthlargest coalfired plant and the largest drycooled power station in the world.
Project Owner/s Stateowned power utility Eskom. Project Description Medupi will be the fourthlargest coalfired power plant and the largest drycooled power station in the world. The power ...
This paper examines the benefits to steam turbine output of retrofitting an aircooled steam condenser with a hybrid (dry/wet) dephlegmator (HDWD) in coalfired, reheat, regeneration cycle.
2009).Putting action to words, Eskom commenced with the construction of two new coalfired power stations, namely the Kusile power station in Emalahleni, situatedin the province of Mpumalanga, and the Medupi power station in Lephalale, these new power ... both will be drycooled stations, unlike the historically installed ...
The Medupi power plant employs a dry cooling system in order to reduce the usage of water. Coal supply for the Medupi power plant
A 1000 MW dry cooled coalfired power station would typically require around GL of water per year. While dry cooling reduces water consumption to around 2 GL/year (from around 17 GL/year), it also reduces sentout efficiency, which leads to higher fuel requirements and higher emissions of carbon dioxide and other greenhouse gases. ...
Medupi Power Station is a drycooled coalfired 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 coalfired power station in the world.
After the 2008 incident involving the failure of a large surface impoundment containing wet coal ash, the EPA began investigating all coalfired power plants employing this wet coal ash management ...
