Diesel Generator
A diesel generator (DG) (also known as a diesel genset) is the combination of a diesel engine with an electric generator (often an alternator) to generate electrical energy. This is a specific case of an engine generator. A diesel compression-ignition engine is usually designed to run on diesel fuel, but some types are adapted for other liquid fuels or natural gas (CNG). Diesel generating sets are used in places without connection to a power grid or as an emergency power supply if the grid fails, as well as for more complex applications such as peak-lopping, grid support, and export to the power grid. Diesel generator size is crucial to minimize low load or power shortages. Sizing is complicated by the characteristics of modern electronics, specifically non-linear loads. Its size ranges around 50 MW and above, an open cycle gas turbine is more efficient at full load than an array of diesel engines, and far more compact, with comparable capital costs; but for regular pa ...

Selective Catalytic Reduction
Selective catalytic reduction (SCR) means converting nitrogen oxides, also referred to as with the aid of a catalyst into diatomic nitrogen (), and water (). A reductant, typically anhydrous ammonia (), aqueous ammonia (), or a urea () solution, is added to a stream of flue or exhaust gas and is reacted onto a catalyst. As the reaction drives toward completion, nitrogen (), and carbon dioxide (), in the case of urea use, are produced. Selective catalytic reduction of using ammonia as the reducing agent was patented in the United States by the Engelhard Corporation in 1957. Development of SCR technology continued in Japan and the US in the early 1960s with research focusing on less expensive and more durable catalyst agents. The first large-scale SCR was installed by the IHI Corporation in 1978.Steam: Its Generation and Uses. Babcock & Wilcox. Commercial selective catalytic reduction systems are typically found on large utility boilers, industrial boilers, and municipal ...

Keel
The keel is the bottom-most longitudinal structural element of a watercraft, important for stability. On some sailboats, it may have a fluid dynamics, hydrodynamic and counterbalancing purpose as well. The keel laying, laying of the keel is often the initial step in constructing a ship. In the British and American shipbuilding traditions, this event marks the beginning date of a ship's construction. Etymology The word "keel" comes from Old English language, Old English , Old Norse , = "ship" or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work ''De Excidio et Conquestu Britanniae'', under the spelling ''cyulae'' (he was referring to the three ships that the Saxons first arrived in). is the Latin word for "keel" and is the origin of the term careening, careen (to clean a keel and the hull in general, often by rolling the ship on its side).

Ship's Wheel
A ship's wheel or boat's wheel is a device used aboard a ship, boat, submarine, or airship, with which a helmsman steering, steers the vessel and controls its course (navigation), course. Together with the rest of the steering mechanism, it forms part of the helm (the term ''helm'' can mean the wheel alone, or the entire mechanism by which the rudder is controlled). It is connected to a mechanical, electric Servomechanism, servo, or hydraulics, hydraulic system which alters the horizontal angle of the vessel's rudder relative to its Hull (watercraft), hull. In some modern ships the wheel is replaced with a simple toggle that remotely controls an electro-mechanical or electro-hydraulic drive for the rudder, with a rudder position indicator presenting feedback to the helmsman. History Until the invention of the ship's wheel, the helmsman relied on a tiller—a horizontal bar fitted directly to the top of the rudder post—or a whipstaff—a vertical stick acting on the arm of the sh ...

Yacht Tender
A yacht tender is a vessel used for servicing and providing support and entertainment to a private or charter yacht. They include utilitarian craft, powered by oar or outboard motor, and high-speed luxury craft, supporting superyachts, powered by inboard engines, some using water-jets. Some superyachts have a support vessel that follows them with bulky items that are not conveniently stowed aboard the main yacht, such as a helicopter, automobile or larger watercraft. History In the early 20th century multiple builders were developing wooden powered yacht tenders, equipped with naphtha steam engines or gasoline motors. By 1929 Chris Craft was building mahogany tenders with powerful inboard engines. Types Tenders may be towed behind a yacht, if they are light and towed at a low speed, or lifted on board, if they are heavy enough to cause damage in a collision or when the vessel cruises at too high a speed for towing. The type of tender varies, according to the size of the ya ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trunk (car)
The trunk (American English) or boot (British English) of a car is the vehicle's main storage or cargo compartment, often a hatch at the rear of the vehicle. It can also be called a tailgate. In Indian English the storage area is known as a dickey (also spelled dicky, dickie, or diggy), and in Southeast Asia as a compartment. Designs The trunk or luggage compartment is most often at the rear of the vehicle. Early designs had an exterior rack on the rear of the vehicle to attach a luggage trunk. Later designs integrated the storage area into the vehicle's body, and eventually became more streamlined. The main storage compartment is normally provided at the end of the vehicle opposite to which the engine is located. Some vehicles have the trunk in front of the passenger compartment, e.g. rear-engined cars like Volkswagen Beetle and Porsche 911, or electric vehicles like Ford F-150 Lightning. This is known as a frunk, a portmanteau of the words "front" and "trunk". The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reverse Transom
In some boats and ships, a transom is the aft transverse surface of the hull that forms the stern of a vessel. Historically, they are a development from the canoe stern (or "double-ender") wherein which both bow and stern are pointed. Transoms add both strength and width to the stern. They may be flat or curved and they may be vertical, raked forward (known as retroussé), or raked aft. In small boats and yachts, this flat termination of the stern is typically above the waterline, but large commercial vessels often exhibit vertical transoms that dip slightly beneath the water. On cruising boats, a counter stern may be truncated to form a "truncated counter stern", in which there is a part of the stern that approximates a transom. Although that standard stern transom is typically vertical, they may be raked such that there is an overhang above the water, as at the bow. A reverse transom is angled from the waterline forwards. On smaller boats such as dinghies, transoms may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plumb Stem
The stem is the most forward part of a boat or ship's bow and is an extension of the keel itself. It is often found on wooden boats or ships, but not exclusively. Description The stem is the curved edge stretching from the keel below, up to the gunwale of the boat. It is part of the physical structure of a wooden boat or ship that gives it strength at the critical section of the structure, bringing together the port and starboard side planks of the hull. Plumb and raked stem There are two styles of stems: ''plumb'' and ''raked''. When the stem comes up from the water, if it is perpendicular to the waterline it is "plumb". If it is inclined at an angle to the waterline it is "raked". (For example, "The hull is single decked and characterized by a plumb stem, full bows, straight keel, moderate deadrise, and an easy turn of bilge.") Stemhead Because the stem is very sturdy, the top end of it may have something attached, either ornamental or functional in nature. On smalle ...

Spreader (sailboat)
A spreader is a spar on a sailing boat used to deflect the shrouds to allow them to better support the mast. The spreader or spreaders serve much the same purpose as the crosstrees and tops in a traditional sailing vessel. Spreaders are used to increase the angle between the rigging and the mast, providing better support, and to adjust the mast's shape and bend. This allows the mast and rigging to be lighter and thinner, reducing their total weight. Spreaders may be made of metal, often aluminium; wood, often spruce; or composite material such as carbon fiber. Spreader design and tuning can be quite complex. The spreaders may be fixed (rigid) or swinging (pivoted at the mast). Most cruising boats have fixed spreaders, but swinging spreaders are found on some racing boats. The length of a boat's beam determines how long the spreaders may be, so some boats have multiple sets of spreaders so the shroud can reach the desired angle from the mast. Boats with tall masts, such as r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
