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.

Superheated steam is steam at a temperature higher than water s boiling point . If saturated steam is heated at constant pressure, its temperature will rise, producing superheated steam. This will occur if saturated steam contacts a surface with a higher temperature. ref name spiraxsarco.com http www.spiraxsarco.com resources steam engineering tutorials steam engineering principles and heat transfer superheated steam.asp ref The steam is then described as superheated by the number of degrees it has been heated above saturation temperature. Superheated steam and liquid water cannot coexist under thermodynamic equilibrium , as any additional heat simply evaporates more water and the steam will become saturated steam. However, under dynamic conditions some degree of superheating is often possible. To produce superheated steam in a power plant or for processes such as drying paper the saturated steam, from the steam drum, is passed through a super heater. The superheater may be radiant, convection or separately fired. Superheated steam is not suitable for Sterilization microbiology sterilization . ref William D.

Unreferenced date January 2007 article A steam drum is a standard feature of a water tube boiler . It is a reservoir of water steam at the top end of the water tubes. The drum stores the steam generated in the water tubes and acts as a phase Vapor liquid separator separator for the steam water mixture . The difference in densities between hot and cold water helps in the accumulation of the hotter water and saturated steam into the steam drum. Image Water tube boiler schematic.png thumb right 400px Schematic diagram of a marine type water tube boiler see the steam drum at the top and feed drum Construction Made from high Carbon Steel with high tensile strength and its working involves temperatures around 390 sup o sup C and pressures well above 350 psi 2.4MPa . The separated steam is drawn out from the top section of the drum and distributed for process. Further heating of the saturated steam will make superheated steam normally used to drive a steam turbine . Saturated steam is drawn off the top of the drum and re enters the furnace in through a superheater . The steam and water mixture enters the steam drum through riser tubes, drum internals consisting of demister separate the water droplets from the steam producing dry steam. The saturated water at the bottom of the steam drum flows down through the downcomer pipe, normally unheated, to headers and water drum. Its accessories include a safety valve, water level indicator and level controller. Feed water of boiler is also fed to the steam drum through a feed pipe extending inside the drum, along the length of the steam drum. A steam drum is used without or in the company of a mud drum feed water drum which is located at a lower level. A boiler with both steam drum and mud water drum is called a bi drum boiler and a boiler with only a steam drum is called a mono drum boiler. The bi drum boiler construction is normally ... rating.

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 shoes 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 .

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

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 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 120 degrees Celsius. Many steam mops have one jet of dry steam but may have as many as 15 jets , moistening a microfibre 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. Weak 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 prhtml09 09279.html ref ref http mystateline.com content fulltext ?cid 131641 ref References Reflist Types of tools Category Cleaning tools ... more details
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.
