Windermere Kettle
A Windermere kettle is a form of steam-operated tea urn or samovar installed on some steam launches. They are a metal vessel containing a few pints of water. Inside the vessel is a steam heating coil. When hot or boiling water is required, a valve is opened and steam from the boat's propulsion boiler is passed through the coil, heating the water. Their exhaust is either overboard or up the funnel, as convenient. Windermere kettles are rapid boilers and can heat enough water to make a pot of tea in only a few seconds. Their name is derived from the popularity of steam launches on Windermere, a lake in the English Lakes, during the Victorian and Edwardian periods. Many of these launches were equipped with such kettles. Misconceptions * The water used is fresh water added separately to the vessel. It is ''not'' condensed steam, nor does the steam mix with it. Boiler steam is contaminated with lubricants, sometimes with chemicals for feedwater treatment, and is definitely not pota ...

Windermere Kettle, Steam Launch Zara Finn
Windermere (sometimes tautology (language), tautologically called Windermere Lake to distinguish it from the nearby town of Windermere, Cumbria (town), Windermere) is the largest natural lake in England. More than 11 miles (18 km) in length, and almost 1 mile (1.5 km) at its widest, it is a ribbon lake formed in a glacial trough after the retreat of ice at the start of the current interglacial period. It has been one of the country's most popular places for holidays and summer homes since the arrival of the Kendal and Windermere Railway's branch line in 1847. Forming part of the border between the historic counties of Lancashire and Westmorland, Windermere is today within the administrative county of Cumbria and the Lake District National Park. Etymology The word 'Windermere' is thought to translate as "'Winand or Vinand's lake'...

Steam Power
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile in the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Samovar
A samovar (russian: самовар, , literally "self-brewer") is a metal container traditionally used to heat and boil water. Although originating in Russia, the samovar is well known outside of Russia and has spread through Russian culture to other parts of Eastern Europe, as well as Western and Central and South Asia. Since the heated water is typically used to make tea, many samovars have a ring-shaped attachment (russian: конфорка, ) around the chimney to hold and heat a teapot filled with tea concentrate. Though traditionally heated with coal or kindling, many newer samovars use electricity to heat water in a manner similar to an electric water boiler. Antique samovars are often prized for their beautiful workmanship. Description Samovars are typically crafted out of plain iron, copper, polished brass, bronze, silver, gold, tin, or nickel. A typical samovar consists of a body, base and chimney, cover and steam vent, handles, tap and key, crown and ring, chimney ...

Steam Launch
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. ...

Teapot
A teapot is a vessel used for steeping tea leaves or a herbal mix in boiling or near-boiling water, and for serving the resulting infusion which is called tea. It is one of the core components of teaware. Dry tea is available either in tea bags or as loose tea, in which case a tea infuser or tea strainer may be of some assistance, either to hold the leaves as they steep or to catch the leaves inside the teapot when the tea is poured. Teapots usually have an opening with a lid at their top, where the dry tea and hot water are added, a handle for holding by hand and a spout through which the tea is served. Some teapots have a strainer built-in on the inner edge of the spout. A small air hole in the lid is often created to stop the spout from dripping and splashing when tea is poured. In modern times, a thermally insulating cover called a tea cosy may be used to enhance the steeping process or to prevent the contents of the teapot from cooling too rapidly. History China ...

Teabag
A tea bag, or the compound teabag, is a small, porous, sealed bag or packet, typically containing tea leaves or the leaves of other herbs, which is immersed in water to steep and make an infusion. Originally used only for tea ('' Camellia sinensis''), they are now made with other tisanes ("herbal teas") as well. Tea bags are commonly made of filter paper or food-grade plastic, or occasionally of silk cotton or silk. The tea bag performs the same function as a tea infuser. Tea bags can be used multiple times until there is no extraction left. Some tea bags have an attached piece of string with a paper label at the top that assists in removing the bag, while also displaying the brand or variety of tea. History Tea bag patents date from 1903 when Roberta Lawson and Mary Molaren, of Milwaukee, Wisconsin, were granted US patent 723287 for a Tea Leaf Holder, which they had filed for in 1901. US patent 723287 was issued on MAR. 24, 1903 to R. G.LAWSON & M. McLAREN for a 'novel t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

English Lakes
The Lake District, also known as the Lakes or Lakeland, is a mountainous region in North West England. A popular holiday destination, it is famous for its lakes, forests, and mountains (or ''fells''), and its associations with William Wordsworth and other Lake Poets and also with Beatrix Potter and John Ruskin. The Lake District National Park was established in 1951 and covers an area of . It was designated a UNESCO World Heritage Site in 2017. The Lake District is today completely within Cumbria, a county and administrative unit created in 1974 by the Local Government Act 1972. However, it was historically divided between three English counties (Cumberland, Westmorland and Lancashire), sometimes referred to as the Lakes Counties. The three counties met at the Three Shire Stone on Wrynose Pass in the southern fells west of Ambleside. All the land in England higher than above sea level lies within the National Park, including Scafell Pike, the highest mountain in England. It a ...

Light Steam Power
''Light Steam Power'' was a magazine dedicated to amateur and small-scale interest in steam power. Its masthead for some years described itself as, ''"Authentic World News on Steam Power for Cars, Launches and Small Stationary Units"''. Publishing history The magazine was self-published by its editor John Ness Walton of Kirk Michael, Isle of Man. It began when he took over an earlier magazine, ''Steam Car Developments and Steam Marine Motors'' in 1945, renaming this in 1949. For most of its existence it was published bi-monthly, although the first and last volumes were published at three- and four-month intervals. In its last years, from 1977 it changed its name to ''Steam Power'' and re-located to Loughborough. The magazine continued under this name until 1981. In more recent years, there was a website maintaining the magazine's archives, but this has now gone. In 2009 an agreement was made with the National Steam Car Association for them to hold the rights to ''Light Steam Powe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potable Water
Drinking water is water that is used in drink or food preparation; potable water is water that is safe to be used as drinking water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. Recent work showed that the most important driver of water turnover which is closely linked to water requirements is energy expenditure. For those who work in a hot climate, up to a day may be required. Typically in developed countries, tap water meets drinking water quality standards, even though only a small proportion is actually consumed or used in food preparation. Other typical uses for tap water include washing, toilets, and irrigation. Greywater may also be used for toilets or irrigation. Its use for irrigation however may be associated with risks. Water may also be unacceptable due to l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boiler Feedwater
Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank. From this tank it then goes back to the steam drum to complete its cycle. The feed water is never open to the atmosphere. This cycle is known as a closed system or Rankine cycle. History of feedwater treatment During the early development of boilers, water treatment was not so much of an issue, as temperatures and pressures were so low that high amounts of scale and rust would not form to such a significant extent, especially if the boiler was “ blown down”. It was general practice to install zinc plates and/or alkaline chemicals to reduce corrosion within the boiler. Many tests had been performed to determine the cause (and possible protection) from corrosi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
