Warrior Run Generating Station
Warrior Run Generating Station, owned by the AES Corporation, is a 205 megawatt cogeneration plant located south of Cumberland, Maryland, at 11600 Mexico Farms Road. In addition to electric power, the plant also produces food-grade carbon dioxide. Design and operation The plant uses fluidized bed combustion (FBC) technology, in which bituminous coal and finely ground limestone are injected, using air, into the boiler. Air keeps the limestone and coal suspended in a fluid-like condition. The limestone reacts with sulfur dioxide, released during combustion of the coal, removing this pollutant from the plant's emissions. With the enhanced sulfur dioxide removal due to the FBC technology, Warrior Run can burn approximately of coal from Maryland each year, which tends to be of a higher sulfur content. During 2007, 100 percent of the coal burned at Warrior Run was mined in Maryland. The FBC boiler operates at a lower temperature compared to other coal-fired boiler technology, reduc ...

Allegany County, Maryland
Allegany County is located in the northwestern part of the U.S. state of Maryland. As of the 2020 census, the population was 68,106. Its county seat is Cumberland. The name ''Allegany'' may come from a local Lenape word, ''welhik hane'' or ''oolikhanna,'' which means 'best flowing river of the hills' or 'beautiful stream'. A number of counties and a river in the Appalachian region of the U.S. are named ''Allegany'', ''Allegheny'', or ''Alleghany''. Allegany County is part of the Cumberland, MD-WV Metropolitan Statistical Area. It is a part of the Western Maryland "panhandle". History The western part of Maryland (including the present Allegany County) was originally part of Prince George's County when Maryland was formed in 1696. This county included six current counties, and by repeated splitting, new ones were generated: Frederick from Prince George's in 1748;Bentley, Elizabeth Petty. ''County Courthouse Book.''

Particulate
Particulates – also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM) or suspended particulate matter (SPM) – are microscopic particles of solid or liquid matter suspended in the air. The term ''aerosol'' commonly refers to the particulate/air mixture, as opposed to the particulate matter alone. Sources of particulate matter can be natural or anthropogenic. They have impacts on climate and precipitation that adversely affect human health, in ways additional to direct inhalation. Types of atmospheric particles include suspended particulate matter; thoracic and respirable particles; inhalable coarse particles, designated PM, which are coarse particles with a diameter of 10 micrometers (μm) or less; fine particles, designated PM, with a diameter of 2.5 μm or less; ultrafine particles, with a diameter of 100 nm or less; and soot. The IARC and WHO designate airborne particulates as a Group 1 carcinogen. Particula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Allegany County, Maryland
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 artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Infrastructure Completed In 2000
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Public Utility Regulatory Policies Act
The Public Utility Regulatory Policies Act (PURPA, ) is a United States Act passed as part of the National Energy Act. It was meant to promote energy conservation (reduce demand) and promote greater use of domestic energy and renewable energy (increase supply). The law was created in response to the 1973 energy crisis, and one year in advance of a second energy crisis. Upon entering the White House, President Jimmy Carter made energy policy a top priority. The law started the energy industry on the road to restructuring. Law PURPA was originally passed with the intention of conserving electric energy, increasing efficiency in facilities and resources used by utility companies, making retail rates for electric consumers more fair, speeding up the creation of hydroelectric energy production at small dams, and conserving natural gas. The main vehicle that the PURPA law used to try and accomplish these goals was by creating a new class of electric generating facilities called “q ...

Alkali
In chemistry, an alkali (; from ar, القلوي, al-qaly, lit=ashes of the saltwort) is a basic, ionic salt of an alkali metal or an alkaline earth metal. An alkali can also be defined as a base that dissolves in water. A solution of a soluble base has a pH greater than 7.0. The adjective alkaline, and less often, alkalescent, is commonly used in English as a synonym for basic, especially for bases soluble in water. This broad use of the term is likely to have come about because alkalis were the first bases known to obey the Arrhenius definition of a base, and they are still among the most common bases. Etymology The word "alkali" is derived from Arabic ''al qalīy'' (or ''alkali''), meaning ''the calcined ashes'' (see calcination), referring to the original source of alkaline substances. A water-extract of burned plant ashes, called potash and composed mostly of potassium carbonate, was mildly basic. After heating this substance with calcium hydroxide (''slaked lim ...

Bottom Ash
Bottom ash is part of the non- combustible residue of combustion in a power plant, boiler, furnace or incinerator. In an industrial context, it has traditionally referred to coal combustion and comprises traces of combustibles embedded in forming clinkers and sticking to hot side walls of a coal-burning furnace during its operation. The portion of the ash that escapes up the chimney or stack is, however, referred to as ''fly ash''. The clinkers fall by themselves into the bottom hopper of a coal-burning furnace and are cooled. The above portion of the ash is also referred to as bottom ash. Most bottom ash generated at U.S. power plants is stored in ash ponds, which can cause serious environmental damage if they experience structural failures. Ash handling processes In a conventional water impounded hopper (WIH) system, the clinker lumps get crushed to small sizes by clinker grinders mounted under water and fall down into a trough from where a water ejector takes them out to ...

Fly Ash
Fly ash, flue ash, coal ash, or pulverised fuel ash (in the UK) plurale tantum: coal combustion residuals (CCRs)is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases. Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash. In modern Fossil fuel power plant, coal-fired power plants, fly ash is generally captured by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys. Together with bottom ash removed from the bottom of the boiler, it is known as coal ash. Depending upon the source and composition of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous solid, amorphous and Crystallinity, crystalline), aluminium oxide (Al2O3) and calcium oxide (CaO), the mai ...
