Rudbar Lorestan Dam
Rudbar Lorestan Dam (Persian Language, Persian: سد رودبار لرستان) is a hydroelectric dam on the Rudbar River, a tributary of the Dez River, in Iran's Lorestan Province with an installed electricity generating capability of 450 MW. It was scheduled to become operational in 2013. Finally, the dam was completed on September 15, 2016. The hydroelectric plant consisting of two 225-MW vertical Francis turbine-generator units has begun operating on May 31, 2017.

Roller-compacted Concrete
Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for Portland cement. The partial substitution of fly ash for Portland Cement is an important aspect of RCC dam construction because the heat generated by fly ash hydration is significantly less than the heat generated by Portland Cement hydration. This in turn reduces the thermal loads on the dam and reduces the potential for thermal cracking to occur. RCC is a mix of cement/fly ash, water, sand, aggregate and common additives, but contains much less water. The produced mix is drier and essentially has no slump. RCC is placed in a manner similar to paving; the material is delivered by dump trucks or conveyors, spread by small bulldozers or specially modified asphalt pavers, and then compacted by vibratory rollers. In dam construction, roll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudbar River
Rudbar ( fa, رودبار, Rudbār) ( Gilaki:, ''rubâr'') is a city and capital of Rudbar County, Gilan Province, Iran. At the 2006 census, its population was 11,454, in 3,303 families. Rudbar is from Tehran and with a variable climate. It is located on the fringes of a valley through which the Sefid River (Rud-e Safid) flows. Rudbar can be considered as a gateway to the Gīlān Province from central Iran. Its name (meaning "by the river" in Persian) is a reference to the river named Sepid Rood (Sepid Roud) that passes by the city. Rudbar is also called "Roodbar Zeitoun (olive)" for the olive gardens in the area. Rudbar's local economy notably includes olives and olive-based products. Groves of olive trees surround the city. Olive oil is produced locally. Rudbar is also known for its cream-hued, handcrafted carpets of fine quality. Despite the olive gardens that may suggest presence of a Mediterranean climate, the winters are very cold in the area. The winds in the S ...

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potentia ...

Francis-type
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 diff ...

Persian Language
Persian (), also known by its endonym Farsi (, ', ), is a Western Iranian language belonging to the Iranian branch of the Indo-Iranian subdivision of the Indo-European languages. Persian is a pluricentric language predominantly spoken and used officially within Iran, Afghanistan, and Tajikistan in three mutually intelligible standard varieties, namely Iranian Persian (officially known as ''Persian''), Dari Persian (officially known as ''Dari'' since 1964) and Tajiki Persian (officially known as ''Tajik'' since 1999).Siddikzoda, S. "Tajik Language: Farsi or not Farsi?" in ''Media Insight Central Asia #27'', August 2002. It is also spoken natively in the Tajik variety by a significant population within Uzbekistan, as well as within other regions with a Persianate history in the cultural sphere of Greater Iran. It is written officially within Iran and Afghanistan in the Persian alphabet, a derivation of the Arabic script, and within Tajikistan in the Tajik alphabet, a der ...

Hydroelectric Dam
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.

Dez River
The Dez River ( fa, دز), the ancient Coprates (;James Knowles (1835) ''A Pronouncing and Explanatory Dictionary of the English Language'' el, Κοπράτης or Κοπράτας), is a tributary of the Karun River and is 400 km long.

List Of Power Stations In Iran
By 2012, Iran had roughly 400 power plant units. By the end of 2013, Iran had a total installed electricity generation capacity of 70,000 MW, which had been increased from 90 MW in 1948, and 7024 MW in 1978. It is planned to add more than 5,000 MW of generation capacity annually to the power grid, which will almost double the total power generation capacity to 122,000 MW by 2022. The government of Iran plans to privatize 20 power plants by September 2010. Iran's peak demand for electricity was 45,693 MW during the summer of 2013. It was predicted Iran accounts for 17.08% of MENA power generation by 2014. The natural gas was the major fuel used to generate electricity in Iran in 2009, accounting for an estimated 56.8% of primary energy demand (PED), followed by oil at 40.8% and hydro power at 1.4%. As of 2010, the average efficiency of power plants in Iran was 38 percent. The figure should reach to 45 percent within five years and 50 percent under Vision 2025. Electricity genera ...

Dams In Iran
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. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
