A boiler is a closed vessel in which drinking water or other fluid is heated. The fluid will not boil. (In THE UNITED STATES, the word "furnace" is generally used if the reason is not to boil the liquid.) The warmed or vaporized liquid exits the boiler for use in a variety of procedures or heating applications,[1][2] including water heating, central heating, boiler-based power era, cooking, and sanitation.

Materials
The pressure vessel of a boiler is usually made of steel (or alloy steel), or of wrought iron historically. Stainless steel, of the austenitic types especially, is not used in wetted parts of boilers due to corrosion and stress corrosion cracking.[3] However, ferritic stainless is often used in superheater sections that will not be exposed to boiling drinking water, and electrically heated stainless shell boilers are allowed under the Western "Pressure Equipment Directive" for production of steam for sterilizers and disinfectors.[4]
[url=https://en.wikipedia.org/wiki/Boiler]https://en.wikipedia.org/wiki/Boiler[/url]
In live steam models, copper or brass is often used since it is more fabricated in smaller size boilers easily. Historically, copper was often used for fireboxes (particularly for steam locomotives), due to its better formability and higher thermal conductivity; however, in more recent times, the high price of copper often makes this an uneconomic choice and cheaper substitutes (such as metal) are used instead.

For much of the Victorian "age group of steam", the only material used for boilermaking was the best quality of wrought iron, with assembly by rivetting. This iron was from specialist ironworks, such as at Cleator Moor (UK), noted for the high quality of their rolled plate and its suitability for high-reliability use in critical applications, such as high-pressure boilers. In the 20th century, design practice instead moved towards the use of steel, which is more powerful and cheaper, with welded building, which is quicker and requires less labour. It should be mentioned, however, that wrought iron boilers corrode much slower than their modern-day steel counterparts, and are less susceptible to localized pitting and stress-corrosion. This makes the longevity of old wrought-iron boilers far superior to those of welded metal boilers.

Cast iron might be used for the heating system vessel of domestic drinking water heaters. Although such heaters are usually termed "boilers" in some countries, their purpose will be to produce hot water, not steam, and they also run at low pressure and try to avoid boiling. The brittleness of cast iron helps it be impractical for high-pressure vapor boilers.

Energy
The foundation of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or gas. Electric vapor boilers use level of resistance- or immersion-type heating elements. Nuclear fission is utilized as a heat source for generating steam also, either directly (BWR) or, in most cases, in specialised heat exchangers called "steam generators" (PWR). Warmth recovery steam generators (HRSGs) use the heat rejected from other processes such as gas turbine.

Boiler efficiency
there are two solutions to gauge the boiler efficiency 1) direct method 2) indirect method

Immediate method -immediate approach to boiler efficiency test is more usable or even more common

boiler efficiency =Q*((Hg-Hf)/q)*(GCV *100 ) Q =Total vapor stream Hg= Enthalpy of saturated steam in k cal/kg Hf =Enthalpy of give food to drinking water in kcal/kg q= level of gas use in kg/hr GCV =gross calorific value in kcal/kg like pet coke (8200 kcal/KG)

indirect method -to gauge the boiler efficiency in indirect method, we are in need of a subsequent parameter like

Ultimate analysis of gasoline (H2,S2,S,C moisture constraint, ash constraint)
percentage of O2 or CO2 at flue gas
flue gas temperature at outlet
ambient temperature in deg c and humidity of air in kg/kg
GCV of energy in kcal/kg
ash percentage in combustible fuel
GCV of ash in kcal/kg
Configurations
Boilers can be classified into the following configurations:

Pot boiler or Haycock boiler/Haystack boiler: a primitive "kettle" in which a fire heats a partially filled drinking water box from below. 18th century Haycock boilers generally produced and stored large volumes of very low-pressure steam, often hardly above that of the atmosphere. These could burn wood or frequently, coal. Efficiency was suprisingly low.
Flued boiler with one or two large flues-an early type or forerunner of fire-tube boiler.

Diagram of the fire-tube boiler
Fire-tube boiler: Here, drinking water partially fills a boiler barrel with a little volume remaining above to support the steam (vapor space). This is the kind of boiler used in nearly all steam locomotives. The heat source is inside a furnace or firebox that needs to be kept completely surrounded by water in order to keep the temp of the heating surface below the boiling point. The furnace can be situated at one end of a fire-tube which lengthens the path of the hot gases, thus augmenting the heating system surface which may be further increased by causing the gases invert direction through another parallel pipe or a bundle of multiple tubes (two-pass or come back flue boiler); additionally the gases may be taken along the sides and then beneath the boiler through flues (3-pass boiler). In case there is a locomotive-type boiler, a boiler barrel expands from the firebox and the hot gases pass through a lot of money of fire tubes inside the barrel which greatly escalates the heating system surface in comparison to a single pipe and further enhances heat transfer. Fire-tube boilers have a comparatively low rate of steam creation usually, but high vapor storage capacity. Fire-tube boilers burn off solid fuels mainly, but are readily adaptable to the people of the gas or liquid variety.

Diagram of a water-tube boiler.
Water-tube boiler: In this kind, pipes filled with water are arranged inside a furnace in a genuine amount of possible configurations. The water pipes connect large drums Often, the low ones containing water and the upper ones water and steam; in other cases, like a mono-tube boiler, water is circulated with a pump through a succession of coils. This type generally provides high vapor production rates, but less storage capacity than the above mentioned. Water tube boilers can be designed to exploit any warmth source and tend to be preferred in high-pressure applications since the high-pressure water/steam is included within small size pipes which can withstand the pressure with a thinner wall structure.
Flash boiler: A flash boiler is a specialized kind of water-tube boiler where pipes are close together and drinking water is pumped through them. A flash boiler differs from the type of mono-tube steam generator in which the tube is permanently filled up with water. In a flash boiler, the tube is kept so hot that water feed is quickly flashed into vapor and superheated. Flash boilers acquired some use in cars in the 19th century which use continued into the early 20th century. .

1950s design steam locomotive boiler, from a Victorian Railways J class
Fire-tube boiler with Water-tube firebox. Sometimes the two above types have been mixed in the next manner: the firebox contains an assembly of water tubes, called thermic siphons. The gases pass through a typical firetube boiler then. Water-tube fireboxes were installed in many Hungarian locomotives,[citation needed] but have met with little success in other countries.
Sectional boiler. Within a ensemble iron sectional boiler, sometimes called a "pork chop boiler" water is contained inside cast iron areas.[citation needed] These sections are assembled on site to create the finished boiler.
Safety
See also: Boiler explosion
To define and secure boilers safely, some professional specialized organizations like the American Society of Mechanical Engineers (ASME) develop specifications and regulation codes. For instance, the ASME Boiler and Pressure Vessel Code is a typical providing a wide range of guidelines and directives to ensure compliance of the boilers and other pressure vessels with security, design and security standards.[5]

Historically, boilers were a way to obtain many serious injuries and property destruction as a consequence to poorly understood engineering principles. Thin and brittle metal shells can rupture, while welded or riveted seams could open up poorly, resulting in a violent eruption of the pressurized steam. When drinking water is converted to vapor it expands to over 1,000 times its original quantity and moves down vapor pipes at over 100 kilometres each hour. Because of this, steam is a great way of moving energy and high temperature around a site from a central boiler house to where it is necessary, but without the right boiler feed water treatment, a steam-raising vegetable are affected from range corrosion and formation. At best, this raises energy costs and can result in poor quality steam, reduced efficiency, shorter vegetation and unreliable operation. At worst, it can result in catastrophic reduction and failing of life. Collapsed or dislodged boiler tubes can also spray scalding-hot steam and smoke out of the air intake and firing chute, injuring the firemen who fill the coal into the open fire chamber. Extremely large boilers providing a huge selection of horsepower to use factories could demolish entire structures.[6]

A boiler that has a loss of feed water and it is permitted to boil dry can be hugely dangerous. If supply water is then sent in to the unfilled boiler, the small cascade of inbound drinking water instantly boils on contact with the superheated metallic shell and leads to a violent explosion that can't be managed even by safety vapor valves. Draining of the boiler can also happen if a leak occurs in the vapor source lines that is larger than the make-up drinking water source could replace. The Hartford Loop was created in 1919 by the Hartford Steam Boiler and Insurance Company as a strategy to help prevent this condition from taking place, and therefore reduce their insurance statements.[7][8]

Superheated steam boiler

A superheated boiler on the steam locomotive.
Main article: Superheater
Most boilers produce vapor to be used at saturation temperatures; that is, saturated vapor. Superheated vapor boilers vaporize water and then further heat the steam in a superheater. This provides steam at higher temp, but can decrease the overall thermal efficiency of the vapor generating herb because the higher vapor temperatures takes a higher flue gas exhaust heat.[citation needed] There are many ways to circumvent this issue, by providing an economizer that heats the give food to water typically, a combustion air heater in the hot flue gas exhaust path, or both. There are advantages to superheated steam that may, and often will, increase overall efficiency of both vapor generation and its own utilization: gains in input temperatures to a turbine should outweigh any cost in additional boiler problem and expense. There could be practical limitations in using moist vapor also, as entrained condensation droplets will harm turbine blades.

Superheated steam presents unique safety concerns because, if any system component fails and allows steam to flee, the high temperature and pressure can cause serious, instantaneous harm to anyone in its path. Since the escaping steam will at first be completely superheated vapor, detection can be difficult, although the extreme heat and sound from such a leak obviously indicates its presence.

Superheater procedure is similar to that of the coils on an air conditioning unit, although for a different purpose. The steam piping is directed through the flue gas route in the boiler furnace. The temp in this field is between 1 typically,300 and 1,600 °C (2,372 and 2,912 °F). Some superheaters are glowing type; that is, they absorb warmth by rays. Others are convection type, absorbing warmth from a fluid. Some are a combination of both types. Through either method, the extreme heat in the flue gas path will heat the superheater steam piping and the steam within also. While the temperature of the vapor in the superheater increases, the pressure of the vapor will not and the pressure remains the same as that of the boiler.[9] Almost all steam superheater system designs remove droplets entrained in the steam to prevent harm to the turbine blading and associated piping.

Supercritical steam generator

Boiler for a power place.
Main article: Supercritical steam generator
Supercritical steam generators are frequently used for the production of energy. They operate at supercritical pressure. As opposed to a "subcritical boiler", a supercritical vapor generator operates at such a high pressure (over 3,200 psi or 22 MPa) that the physical turbulence that characterizes boiling ceases that occurs; the fluid is liquid nor gas but a super-critical fluid neither. There is absolutely no generation of steam bubbles within water, because the pressure is above the critical pressure point of which steam bubbles can develop. As the fluid expands through the turbine phases, its thermodynamic state drops below the critical point as it does work turning the turbine which changes the electrical generator from which power is ultimately extracted. The liquid at that point may be considered a mix of vapor and liquid droplets as it passes into the condenser. This leads to less fuel use and for that reason less greenhouse gas production slightly. The word "boiler" shouldn't be used for a supercritical pressure vapor generator, as no "boiling" occurs in this product.

Boiler fittings and accessories
Pressuretrols to control the steam pressure in the boiler. Boilers generally have two or three 3 pressuretrols: a manual-reset pressuretrol, which functions as a protection by setting top of the limit of vapor pressure, the operating pressuretrol, which settings when the boiler fires to keep pressure, and for boilers equipped with a modulating burner, a modulating pressuretrol which settings the quantity of fire.
Protection valve: It is utilized to relieve pressure and stop possible explosion of a boiler.
Water level indications: They show the operator the level of liquid in the boiler, known as a sight glass also, water measure or drinking water column.
Bottom blowdown valves: They offer a way for removing solid particulates that condense and lay on the bottom of the boiler. As the name implies, this valve is usually located directly on the bottom of the boiler, and is sometimes opened to use the pressure in the boiler to push these particulates out.
Continuous blowdown valve: This allows a small quantity of water to flee continuously. Its purpose is to prevent water in the boiler becoming saturated with dissolved salts. Saturation would lead to foaming and cause water droplets to be transported over with the steam - a condition known as priming. Blowdown is often used to monitor the chemistry of the boiler drinking water also.
Trycock: a kind of valve that is often use to manually check a liquid level in a tank. Most commonly found on a water boiler.
Flash tank: High-pressure blowdown enters this vessel where in fact the steam can 'flash' safely and become used in a low-pressure system or be vented to atmosphere as the ambient pressure blowdown moves to drain.
Automatic blowdown/constant heat recovery system: This technique allows the boiler to blowdown only once makeup water is moving to the boiler, thereby transferring the maximum amount of heat possible from the blowdown to the makeup water. No flash container is normally needed as the blowdown discharged is near to the temperature of the makeup water.
Hand openings: They may be metal plates installed in openings in "header" to allow for inspections & installing tubes and inspection of internal surfaces.
Vapor drum internals, a series of screen, scrubber & cans (cyclone separators).
Low-water cutoff: It is a mechanical means (usually a float switch) that is utilized to turn off the burner or shut off fuel to the boiler to prevent it from running once the drinking water runs below a certain point. If a boiler is "dry-fired" (burned without drinking water in it) it can cause rupture or catastrophic failure.
Surface blowdown series: It provides a way for removing foam or other lightweight non-condensible substances that have a tendency to float together with the water inside the boiler.
Circulating pump: It really is designed to circulate drinking water back again to the boiler after it has expelled a few of its heat.
Feedwater check valve or clack valve: A non-return stop valve in the feedwater line. This can be suited to the relative aspect of the boiler, just below water level, or to the very best of the boiler.[10]
Top feed: With this design for feedwater injection, the water is fed to the very best of the boiler. This can reduce boiler fatigue triggered by thermal stress. By spraying the feedwater over some trays the water is quickly warmed which can reduce limescale.
Desuperheater tubes or bundles: Some tubes or bundles of pipes in the water drum or the vapor drum made to cool superheated vapor, in order to supply auxiliary equipment that does not need, or may be damaged by, dry out vapor.
Chemical substance injection line: A link with add chemicals for controlling feedwater pH.
