Carryover with steam , in steam technology, refers to transport of moisture and impurities with steam. The moisture carryover with steam is quantified by the mass flow rate of liquid water per mass flow rate of steam. In boiler s or steam generator s producing saturated steam , it is typically about 0.1 but may increase with fouling and boiler impurities. The carryover of impurities for example, sodium, chloride, copper, silica with steam can be divided into two parts ref Procedure for the Measurement of Carryover Boiler Water into Steam, The International Association for the Properties of Water and Steam, Technical Guidance Document, Berlin, September, 2008. http www.iapws.org relguide Carryover.pdf pdf ref mechanical carryover of the impurity with liquid water droplets entrained with the steam, and vaporous carryover of the impurity in steam. The total carryover is a sum of the mechanical and vaporous carryover. The vaporous carryover generally increases with increasing steam pressure. In low pressure boilers, the mechanical carryover of impurities prevails, possibly with the exception of more volatile impurities, like silica. The impurity carryover can cause corrosion and fouling of steam turbines, reheaters, and superheaters. References reflist Category Boilers ... more details

A Steam separator , sometimes referred to as a moisture separator , is a device for separating water droplets from steam. The simplest type of steam separator is the steam dome on a steam locomotive . Stationary boiler s and nuclear reactors may have more complex devices which impart a spin to the steam so that water droplets are thrown outwards by centrifugal force and collected. It is important to remove water droplets from steam because In all engines, wet steam reduces the thermal efficiency In piston engines, water can accumulate in the cylinders and cause a Hydrolock hydraulic lock which will damage the engine In thermal power station s, water droplets in high velocity steam coming from nozzles or vanes in a steam turbine can impinge on and erode turbine internals such as turbine blades.

A steam brake is a type of brake for steam locomotive s and their tender rail tenders , whereby a steam cylinder locomotive cylinder works directly on the brake linkages. Steam brakes were primarily used on railways where vacuum brakes were used to brake the train, but where there was no vacuum brake on the steam locomotive itself, as for example in the United Kingdom , or where there was only a cable operated brake e.g. a Heberlein brake running along the train, like for example in Kingdom of Saxony Saxony on the narrow gauge railways. Steam brakes are usually found today on heritage steam locomotives. Operation Steam is supplied to the steam brake cylinders from the locomotive boiler via a valve the brake valve which may have several fixed settings or be infinitely variable. The piston in the steam cylinder is set in motion by the steam admitted, the piston rod transfers the brake force via a system of rods to the brake block s of the vehicle, thus achieving the braking effect. A return spring returns the piston to its rest position as soon as the steam supply is interrupted. The expanded and condensed steam is drained from the steam cylinder through a drain valve Entw sserungsventil . Direct steam brake A steam brake acts directly and immediately the sudden opening of the brake valve can result in a slight overbraking by locking the wheels. The operation of a steam brake therefore requires a great deal of experience from the engine driver . Vacuum controlled steam brake A steam brake can be operated directly by a lever valve and also indirectly together with the vacuum brake. In the latter case, a control valve linked to the vacuum system controls the admission of steam to the brake cylinder, so that the steam brake can be activated automatically in an emergency or if the train separates the so called automatic steam brake .

A steam mop is a mop that uses steam to clean floors and carpets. Unlike a regular mop, which requires cleaning agents such as bleach or detergent, the steam mop uses the heat from the steam to disinfect the floors. A microfibre pad is often placed right underneath the steam jet to trap dirt. Most steam mops have a small water tank, and often provide dry steam. How a steam mop works A steam mop works by heating up the water inside the reservoir to temperatures of about 248 degrees Fahrenheit. Many steam mops have one jet of dry steam but may have as many as 15 jets , moistening a microfiber pad placed underneath. The steam helps soak the pad and dirt is drawn off ground. Unlike regular mops though, steam mops do not leave a residue on the floor and often clean through the dirt. The intense heat of the steam can kill about 99 percent of the bacteria and household dust mites. Steam mops can disinfect floors, restore shine, kill dust mites, and remove some stains. Safety While steam mops have advantages, the heat from the steam and electricity are safety issues. Steam can burn skin quickly. There have been recalls of steam mops related to burn hazards. ref http www.cpsc.gov CPSCPUB PREREL prhtml10 10117org.html ref ref http www.cpsc.gov cpscpub prerel prhtml09 09279.html ref References Reflist Types of tools Category Cleaning tools fa ... more details

unreferenced date March 2010 A steam shower is a type of bathing where a humidifying steam generator produces water vapor that is dispersed around a person s body. A steam shower is essentially a steam room that offers the typical features of a bathroom shower. Steam showers are generally found in self contained enclosures that prevent the water vapour from escaping into the rest of the room, avoiding damage to drywall , paint , or wallpaper . A steam shower can be a social affair if the enclosure sits more than one person. Steam showers combine the functionality of a standard steam room with many additional features including a shower. Steam showers are available in a variety of materials, including but not limited to tile , acrylic resin acrylic , fiberglass , Rock geology stone , and wood . History Steam showers have evolved from the steambath which is thought to have been invented during the height of the Roman Empire. Ancient Roman bathing Ancient Roman baths served many community and social functions within Roman society. These Roman baths were supplied by natural hot springs from beneath the ground. Features A steam shower could be a regular shower with the added steam feature that is powered by a steam generator. In addition to plain steam, modern steam showers provide additional features such as foot massage rs, ceiling rain showers, television , radio s, telephone s, audio input from an MP3 or CD player , chromatherapy or aromatherapy . A steam shower can use solar thermal technology and lessen the electricity bill drastically by heating the water with the sun.

A steam dummy or dummy engine , in the United States of America and Canada , was a steam engine enclosed in a wood en box structure made to resemble a railroad passenger coach. Steam dummies had some popularity in the first decades of railroading in the U.S., from the 1830s but passed from favor after the United States Civil War Civil War . It was thought that the more familiar appearance of a coach presented by a steam dummy, as compared to a conventional engine, would be less likely to frighten horses when these trains had to operate in city street s. Later it was discovered that it was actually the noise and motion of the operating gear of a steam engine that frightened horse s, rather than the unfamiliar outlines of a steam engine. Many steam dummies were simply locomotive s enclosed in coach s clothing, but some combined an actual railroad coach in the same body with the locomotive, creating an all in one vehicle that was a predecessor of later self propelled rail cars, usually powered by electricity or petrol .

Unreferenced date December 2009 Orphan date December 2009 A steam brig is a two masted sailing ship with auxiliary steam engine steam power . The advantage was supposed to be that the ship could sail up wind when it was convenient, and additionally, it could use the steam power to move relative to the wind to obtain a more advantageous angle to the wind. In practice, the disadvantages combined rather than the advantages. The type had great wind resistance, leading to an increased use of fuel up wind compared to a pure steam ship. At the same time, the requirement to store coal reduced the cargo space over that of a sailing ship. It thus combined the slow speed, high maintenance and poor righting ability to resist capsize and wind of a sailing ship with the small cargo space and fuel expense of a steam ship.

Unreferenced date December 2009 Steam railroad is a term used in the United States of America United States to distinguish conventional heavy railroad s from street railway s, interurban streetcar lines, and other light railway s usually dedicated primarily to passenger transport. Steam railroads were so called because they were typically powered by steam locomotives hauling unpowered passenger or freight cars, as opposed to light railways that were more typically powered by electric ity, cable car railway cable or animal power. The term steam railroad continued in use in the generic sense long after most steam power disappeared from American railroads by the 1950s, but is now only used to describe tourist railroads that run steam locomotives.
