Mary-Ann (turbine Generator)
Mary-Ann was the nickname given to the first steam turbine used in a public utility to generate electricity in America. Hartford Electric Light Company of Hartford, Connecticut, realized an extra demand for electricity in 1900 and decided in 1901 to purchase this steam turbine generator. The turbine, built by Westinghouse and rated at 1.5 megawatts, ran at Hartford Electric's Pearl Street plant from 1901 to 1905. History Connecticut was prosperous at the beginning of the twentieth century. This attracted large populations of people. Many industries developed and needed electricity (whose original use was solely lighting) to run their machinery. Hartford Electric Light Company of Hartford, Connecticut, realizing this extra demand for electricity decided in 1900 to install a massive three thousand horsepower machine to generate this huge amount of electricity that was needed. Description Hartford Electric Light Company (HELCO) ordered in January 1901 a Westinghouse-Parsons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kilowatt
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). : ...

Alternating Current
Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source of DC power is a battery cell in a flashlight. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa. In certain applications, like guitar amplifiers, different waveforms are used, such as triangular waves or square waves. Audio a ...

Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or ''voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power sup ...

Worthington Company
The Worthington Corporation was a diversified American manufacturer that had its roots in Worthington and Baker, a steam pump manufacturer founded in 1845. In 1967 it merged with Studebaker and Wagner Electric to form Studebaker-Worthington. This company was in turn acquired by McGraw-Edison in 1979. Worthington Pump Works (1845–1899) Worthington and Baker, manufacturers of hydraulic machinery such as steam pumps and meters, was founded by Henry Rossiter Worthington, Henry R Worthington and William H. Baker. Worthington was the inventor of the direct acting steam pump. The first foundry was near the Brooklyn Navy Yard. In 1854 the partners moved to Van Brunt Street in Brooklyn. The partnership was dissolved around 1860 when Baker died. A new partnership called Henry R. Worthington, or Worthington Hydraulic Pump Works, was formed in 1862. The United States Navy used Worthington pumps to pump: boiler feed water, bilge water, fire fighting, and general services (https://www.asme ...

Water-tube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Connecticut River
The Connecticut River is the longest river in the New England region of the United States, flowing roughly southward for through four states. It rises 300 yards (270 m) south of the U.S. border with Quebec, Canada, and discharges at Long Island Sound. Its watershed encompasses , covering parts of five U.S. states and one Canadian province, via 148 tributaries, 38 of which are major rivers. It produces 70% of Long Island Sound's fresh water, discharging at per second. The Connecticut River Valley is home to some of the northeastern United States' most productive farmland, as well as the Hartford–Springfield Knowledge Corridor, a metropolitan region of approximately two million people surrounding Springfield, Massachusetts, and Hartford, Connecticut. History The word "Connecticut" is a corruption of the Mohegan word ''quinetucket'', which means "beside the long, tidal river". The word came into English during the early 1600s to name the river, which was also called simply "Th ... [...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] |
