Andijan Dam
The Andijan Dam is a buttress dam on the river Kara Darya near Andijan in Andijan Region, Uzbekistan. Its reservoir covers and stretches into neighboring Osh Region, Kyrgyzstan. The dam serves several purposes to include irrigation in the Fergana Valley and hydroelectric power production. Water released from the dam can enter a canal on either side of the river downstream. The dam has two power stations located at its base, Andijan 1 and Andijan 2. The former contains four 35 MW turbine-generators and the latter contains two 25 MW Francis turbine-generators for a total installed capacity of 190 MW. Construction on the dam began in 1969 and the generators in Andijan 1 were commissioned between 1974 and 1984. Construction on Andijan 2 began in 2007 and it was commissioned on 2 September 2010. It cost US$28.5 million of which US$15.93 million was supplied by the Exim Bank of China. The artificial lake created by this dam is the Andijan Reservoir (also: ''Kampyrravat Reservoir'' or ''K ...

Andijan
Andijan (sometimes spelled Andijon or Andizhan in English) ( uz, Andijon / Андижон / ئەندىجان; fa, اندیجان, ''Andijân/Andīǰān''; russian: Андижан, ''Andižan'') is a city in Uzbekistan. It is the administrative, economic, and cultural center of Andijan Region. Andijan is a district-level city with an area of and it had 458,400 inhabitants in 2022. Andijan is located in the south-eastern edge of the Fergana Valley near Uzbekistan's border with Kyrgyzstan. Andijan is one of the oldest cities in the Fergana Valley. In some parts of the city, archeologists have found items dating back to the 7th and 8th centuries. Historically, Andijan was an important city on the Silk Road. The city is perhaps best known as the birthplace of Babur who, following a series of setbacks, finally succeeded in laying the basis for the Mughal dynasty in the Indian subcontinent and became the first Mughal emperor. Andijan also gained notoriety in 2005 when government forc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for d ...

Hydroelectric Power Stations In Uzbekistan
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Dams In The Aral Sea Basin
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.
