Hatfield's Ferry Power Station
Hatfield's Ferry Power Station was a 1.7-gigawatt (1,700 MW), coal power plant located in Greene County, Pennsylvania. The plant was operated by FirstEnergy. It began operations in 1969 and was shut down in 2013. The three Emission stacks were imploded March 4th, 2023 at 11:00 AM History Hatfield's Ferry's construction commenced in 1963 and began generation in 1969 under the operations of Allegheny Energy. FirstEnergy assumed operations of Hatfield's Ferry following its merger with Allegheny Energy in 2010. Environmental mitigation In the mid-1990s, Allegheny Energy installed a control system which reduced the plant's nitrogen oxide () emissions. In 2001, Hatfield's Ferry added a natural gas reburn system. In that same year, Allegheny Energy introduced a passive treatment system where groundwater from the fly ash landfill is treated with wetlands. Allegheny Energy commissioned a flue-gas desulfurization (FGD) system, designed by Babcock & Wilcox, to be installed at Hatfield's ...

Sulfur Dioxide
Sulfur dioxide (IUPAC-recommended spelling) or sulphur dioxide (traditional Commonwealth English) is the chemical compound with the formula . It is a toxic gas responsible for the odor of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of sulfur- bearing fossil fuels. Structure and bonding SO2 is a bent molecule with ''C''2v symmetry point group. A valence bond theory approach considering just ''s'' and ''p'' orbitals would describe the bonding in terms of resonance between two resonance structures. The sulfur–oxygen bond has a bond order of 1.5. There is support for this simple approach that does not invoke ''d'' orbital participation. In terms of electron-counting formalism, the sulfur atom has an oxidation state of +4 and a formal charge of +1. Occurrence Sulfur dioxide is found on Earth and exists in very small concentrations and in the atmosphere at about 1 ppm. On other planets, ...

Buildings And Structures In Greene County, Pennsylvania
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former Coal-fired Power Stations In The United States
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ...

Energy Infrastructure Completed In 1969
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has mass when ...

Pittsburgh Post-Gazette
The ''Pittsburgh Post-Gazette'', also known simply as the PG, is the largest newspaper serving metropolitan Pittsburgh, Pennsylvania. Descended from the ''Pittsburgh Gazette'', established in 1786 as the first newspaper published west of the Allegheny Mountains, the paper formed under its present title in 1927 from the consolidation of the ''Pittsburgh Gazette Times'' and ''The Pittsburgh Post''. The ''Post-Gazette'' ended daily print publication in 2018 and has cut down to two print editions per week (Sunday and Thursday), going online-only the rest of the week. In the 2010s, the editorial tone of the paper shifted from liberal to conservative, particularly after the editorial pages of the paper were consolidated in 2018 with '' The Blade'' of Toledo, Ohio. After the consolidation, Keith Burris, the pro-Trump editorial page editor of '' The Blade'', directed the editorial pages of both papers. Early history ''Gazette'' The ''Post-Gazette'' began its history as a four-page w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Gas Power Plant
A gas-fired power plant or gas-fired power station or natural gas power plant is a thermal power station which burns natural gas to generate electricity. Natural gas power stations generate almost a quarter of world electricity and a significant part of global greenhouse gas emissions and thus climate change. However they can provide seasonal dispatchable generation to balance variable renewable energy where hydropower or interconnectors are not available. Basic concepts: heat into mechanical energy into electrical energy A gas-fired power plant is a type of fossil fuel power station in which chemical energy stored in natural gas, which is mainly methane, is converted successively into: thermal energy, mechanical energy and, finally, electrical energy. Although they cannot exceed the Carnot cycle limit for conversion of heat energy into useful work the excess heat may be used in cogeneration plants to heat buildings, produce hot water, or to heat materials on an industrial ...
