Connah's Quay Power Station
Connah's Quay Power Station is a 1,420 MW gas-fired power station to the west of Connah's Quay in Flintshire in North Wales. It is next to the A548, being tightly situated between the road and the south bank of the River Dee. History The current station is the successor to the first station in the area, a coal-fired power station, located less than a kilometre to the southwest of the current station. The old station was opened on the 16 September 1954 by Lord Citrine, the chairman of the British Electricity Authority. The station was originally planned to only be of 60 megawatts (MW), but it was realised that a larger station would be needed. The coal-fired station was built in three stages, each stage having two 30 MW generating sets, giving a total generating capacity of 180 MW. The stages were completed in 1953, 1955 and 1957. Coal was provided by train from the Point of Ayr undersea colliery. There were two unloading sidings controlled by Rockcliffe Hal ...

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] |

Wobbe Index
The Wobbe index (WI) or Wobbe number is an indicator of the interchangeability of fuel gases such as natural gas, liquefied petroleum gas (LPG), and town gas and is frequently defined in the specifications of gas supply and transport utilities. If V_C is the higher heating value, or higher calorific value, and G_S is the specific gravity, the Wobbe index, I_W, is defined as: :I_W = \frac . :G_S = \frac = \frac \rho_ is the density of the gas at standard conditions (0 °C, 101.325 kPa), \rho_ is the density of air at standard conditions, M is the molar mass of the gas and M_ is the molar mass of air which is about 28.96 kg/kmol. The Wobbe index is used to compare the combustion energy output of different composition fuel gases in an appliance (fire, cooker etc.). If two fuels have identical Wobbe indices then for given pressure and valve settings the energy output will also be identical. Typically variations of up to 5% are allowed as these would not be noticeable to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Transmission System
The United Kingdom's National Transmission System (NTS) is the network of gas pipelines that supply gas to about forty power stations and large industrial users from natural gas terminals situated on the coast, and to gas distribution companies that supply commercial and domestic users. It covers Great Britain, i.e. England, Wales and Scotland. History Origins The system originated in the construction during 1962–3 of the 200-mile (320 km) high-pressure methane pipeline from Canvey Island (on the Essex coast) to Leeds. Imported liquified natural gas (LNG) from Algeria was turned into gas at the Canvey terminal and supplied to the pipeline, providing eight of the twelve area gas boards with access to natural gas. The gas was initially used to manufacture town gas, either as a feedstock in gas reforming processes or to enrich lean gases such as that produced by the Lurgi coal gasification process. The pipeline was 18-inch (460 mm) in diameter and operated at 1,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Conditions For Temperature And Pressure
Standard temperature and pressure (STP) are standard sets of conditions for experimental measurements to be established to allow comparisons to be made between different sets of data. The most used standards are those of the International Union of Pure and Applied Chemistry (IUPAC) and the National Institute of Standards and Technology (NIST), although these are not universally accepted standards. Other organizations have established a variety of alternative definitions for their standard reference conditions. In chemistry, IUPAC changed its definition of standard temperature and pressure in 1982: * Until 1982, STP was defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 1 atm (101.325 kPa). * Since 1982, STP has been defined as a temperature of 273.15 K (0 °C, 32 °F) and an absolute pressure of exactly 105 Pa (100 kPa, 1 bar). STP should not be confused with the standard state com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Douglas Complex
The Douglas Complex is a high system of three linked platforms in the Irish Sea, off the North Wales coast. The Douglas oil field was discovered in 1990, and production commenced in 1996. Now operated by Eni, the complex consists of the wellhead platform, which drills into the seabed, a processing platform, which separates oil, gas and water, and thirdly an accommodation platform, which is composed of living quarters for the crew. This accommodation module was formerly the Morecambe Flame jack-up drilling rig. The Douglas Complex is also the control hub for other platforms in the area, and provides power for all platforms. It also offers recreational, catering and medical facilities for up to 80 personnel. Oil from the Lennox, Hamilton, and Hamilton North unmanned satellite platforms is received and blended at the complex. Fluids from the Lennox installation via the gas pipeline are treated on the Douglas installation in the 3-phase (oil, gas and produced water) Lennox ...

Liverpool Bay
Liverpool Bay is a bay of the Irish Sea between northeast Wales, Cheshire, Lancashire and Merseyside to the east of the Irish Sea. The bay is a classic example of a region of freshwater influence. Liverpool Bay has historically suffered from reduced oxygen content from prior massive discharges of sewage sludge, according to C. Michael Hogan. The rivers Alt, Clwyd, Dee, Ribble and Mersey drain into the bay. The bay is littered with wrecks and has many dive sites. The bay also contains several oil and gas fields including the Douglas Complex, with a combined daily capacity (January 2008) of 60,000 barrels. The UK's first major offshore wind farm, North Hoyle, is located in the south of the bay, which is a busy shipping route to the Mersey Docks. The land area around the bay is occasionally referred to as the "Liverpool Bay Area". Though the term is seen by some as a possible official alternative to Merseyside, it is more often used to describe a much wider area which may ...

Point Of Ayr
:''There are two other similarly named points in the British Isles: Point of Ayre, Isle of Man and Point of Ayre, Orkney, Scotland.'' Point of Ayr ( cy, Y Parlwr Du) is the northernmost point of mainland Wales. It is situated immediately to the north of Talacre in Flintshire, at the mouth of the Dee estuary. It is to the southwest of the Liverpool Bay area of the Irish Sea. It is the site of a RSPB (Royal Society for the Protection of Birds) nature reserve RSPB Dee Estuary Point of Ayr, and is part of Gronant and Talacre Dunes Site of Special Scientific Interest. Coal For many years a colliery operated at Point of Ayr at the northern extremity of the Flintshire Coalfield; it was one of the last remaining operational deep mines in Wales. The first trial borings took place in 1865, under the direction of Lord Mostyn, owner of Mostyn Colliery, a few miles away. The borings seemed successful, and the Prestatyn Coal Company was formed to commence operations proper, however the pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
