Brunot Island
Brunot Island (also spelled Brunot's Island) is a island in the Ohio River. It is officially part of the Marshall-Shadeland neighborhood of Pittsburgh, in Allegheny County, Pennsylvania in the United States. It was named for Dr. Felix Brunot who settled the island with his extended family in the late 1700s. The family entertained the Lewis and Clark Expedition on the island in August 1803. The island is home to the Brunot Island Generating Station, a 315 MW fossil fuel power plant. The Ohio Connecting Railroad Bridge crosses the Ohio River at the island. The island does not otherwise connect to the land, and all vehicular traffic must use a ferry to access the island. The employees of the power plant use a pedestrian walkway on the railroad bridge to go to work. The walkway is not accessible to the public. From 1903 to 1914, the island was the home of Brunots Island Race Track. Brunot Island Generating Station *Type: Fossil fuel; oil and natural gas *Net capacity: 315 MW (me ...

Islands Of The Ohio River
An island or isle is a piece of subcontinental land completely surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges Delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental islands and oceanic islands. There are also artificial islands (man-made islands). There are about 900,000 official islands in the world. This number consists of all the officially-reported islands of each country. The total number of islands in the world is unknown. There may be hundreds of thousands of tiny islands that are unknown and uncounted. The number of sea islands in the world is estimated to be more than 200,000. The t ...

River Islands Of Pennsylvania
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, spring ...

Combined Cycle
A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy. On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant. The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant. Combining two or more thermodynamic cycles improves overall efficiency, which reduces fuel costs. The principle is that after completing its cycle in the first engine, the working fluid (the exhaust) is still hot enough that a second subsequent heat engine can extract energy from the heat in the exhaust. Usually the heat passes through a heat exchanger so that the two engines can use different working fluids. By generating power from multiple streams of work, the overall efficiency can be increased by 50–60%. That is, from an overall efficiency of the system of say 34% for a simple cycle, to as much as 64% ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peaking Power Plant
Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power. Peak load power plants are dispatched in combination with base load power plants, which supply a dependable and consistent amount of electricity, to meet the minimum demand. Although historically peaking power plants were frequently used in conjunction with coal baseload plants, peaking plants are now used less commonly. Combined cycle gas turbine plants have two or more cycles, the first of which is very similar to a peaking plant, with the second running on the waste heat of the first. That type of plant is often capable of rapidly starting up, albeit at reduced efficiency, and then over some hours transitioning to a more efficient baseload generation mode. C ...

Simple Cycle Combustion Turbine
A Simple-Cycle Combustion Turbine (SCCT) is a type of gas turbine most frequently used in the power generation, aviation (jet engine), and oil and gas industry (electricity generation and mechanical drives). The simple-cycle combustion turbine follows the Brayton Cycle and differs from a combined cycle operation in that it has only one power cycle (i.e. no provision for waste heat recovery). Advantages There are several advantages of an SCCT. The primary advantage of a SCCT is the high power generated to weight (or size) ratio, when compared to alternatives. Another advantage is the ability for it to quickly reach full power. Unlike other baseload power plants that may have a minimum time of being online once started. This "minimum up" is a common term in the power industry when referring to this requirement. Therefore, SCCTs are usually used as peaking power plants, which can operate from several hours per day to a couple of dozen hours per year, depending on the electricity deman ...

Megawatts
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own 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, the rate at which 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 potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : \mathr ...
