		In these cases, solubilized sodium ferroite is removed from the base tube metal, but then hydrolyzes and precipitates elsewhere in the boiler as magnetite when the concentrated water is diluted by normal boiler water.
		Virtually all types of tubes, which carry water or steam and are exposed to high operating temperatures are susceptible to this type of failure.
		The presence of dissolved oxygen in boiler water causes the cathode of any corrosion cell to depolarize, thereby sustaining the corrosion process.

	Boiler Efficiency
		Firetube boilers are often characterized by their number of passes, referring to the number of times the combustion (or flue) gases flow the length of the pressure vessel as they transfer heat to the water.
		In firetube boilers, the combustion gases pass inside boiler tubes, and heat is transferred to water on the shell side.
		Scotch marine boilers are typically cylindrical shells with horizontal tubes configured such that the exhaust gases pass through these tubes, transferring energy to boiler water on the shell side.

	Boiler Types
		There is an optimum sizing and arrangement for the water tubes, which depends on the boiler's dimensions.
		Pot boilers have large water capacity and simple to steam.
		The pot boiler, show in Figure 2, is the simplest type and consists of a cylindrical copper tube with stayed end plates.

	boiler on Encyclopedia.com
		Two types of boilers are most common—fire-tube boilers, containing long steel tubes through which the hot gases from the furnace pass and around which the water to be changed to steam circulates, and water-tube boilers, in which the conditions are reversed.
		It consists of two principal parts: the furnace, which provides heat, usually by burning a fuel, and the boiler proper, a device in which the heat changes water into steam.
		The construction of boilers in the United States is governed by the American Society of Mechanical Engineers' Boiler Construction Code.

	Steam Power
		The simplest of the watertube boilers is called a monotube boiler, which in essence is nothing more than a coiled copper tube (like a moonshine coil) with water in it and a fire underneath it.
		A firetube boiler basically consists of a tank full of water with hollow tubes running through it.
		First, a watertube boiler will not allow for the fluctuations in pressure that a firetube boiler will.

	New Jersey Scuba Diver - Artifacts & Shipwrecks - Boilers
		In a water tube boiler the water is superheated in tubes exposed to the hot gases.
		Boilers on nineteenth-century wrecks such as the Delaware tend to be collapsed or caved in, exposing the fire tubes and other interior components.
		A significant advantage of this type is that there is less chance of catastrophic failure, as there is not a great amount of water in the boiler, nor are there large mechanical elements subject to failure.

		Boiler size, operating pressure, steam demand, load variables, feed water quality, internal condition, feed water temperature, operating history, available staff time, boiler design, required chemical approvals and more play a part in the type of program to be selected.
		Boiler corrosion most frequently is caused by dissolved oxygen, typically resulting in localized pits which effect rapid penetration and tube failure.
		If the boiler is undersized or subject to sudden large increases in load, surging of the boiler water into the steam may occur.

	DESTRUCTORS - LoveToKnow Article on DESTRUCTORS
		The high temperatures attained are utilized by installng one boiler, preferably of the Babcock and Wilcox water-tube type, for each pair of cells, so that the gases, on their way from the combustion chamber, to the main flue, pass three times between the boiler tubes.
		The actual calorific value of the refuse material necessarily varies, but, as a general average, with suitably designed and properly managed plant, an evaporation of I lb of water per pound of refuse burned is a result which may be readily attained, and affords a basis of calculation which engineers may safely adopt in practice.
		Destructors of the Sterling type, combined with electricpower generating stations, are installed at Hackney (1901), Bermondsey (1902) and Frederiksberg (1903)the first- St li named plant being probably the most powerful com- er 1I~.

	Inventory & Technical Information, Boiler Tubing, Brass and Copper Tube Selection Guide
		Tubes of this material have found wide usage in sugar refining, chemical processing, feed water heaters and condensers, air-conditioners and refrigerators, cryogenic exchangers and evaporators and distribution lines for hot and cold waters in domestic, industrial and commercial applications.
		The media is normally (1) cooling water, fresh, sea, brackish or chemically treated (2) steam and condensate, or (3) chemicals and petrochemicals exposed to the inside or outside surface of the tube.
		The selection of the best tube alloy for a particular application is normally based upon alloy corrosion resistant characteristics in addition to resistance to operating temperatures and pressures.

		Firetube boilers have a fairly large amount of contained water so that there is a considerable amount of stored heat energy in the boiler.
		Firetube boilers are generally built similar to a shell and tube heat exchanger.
		Boilers have been made in almost all conceivable shapes and arrangements of furnaces and flues, for burning all knids of fuels, for use with natural draft or mechanical draft firing equipment.

	History of the Steam Engine
		The surface of the water in the tube would be precisely at the same level as the water in the boiler.
		If water came from this check cock, he knew the boiler contained too much water and was not operating at peak efficiency.
		The bottom cock was always opened first and the engineer expected to see a small jet of water issue from it.

		There are duisdantages to the use of bank-side reservoirs in that they take a very large area of land adjacent to the river and in summer they can support explosive growths of blue-green algae which can reach bloom proportions and cause unacceptable levels of toxins to be released into the water.
		The final structure roughly divided the building into three - the huge main turbine hall in the centre with the smaller boiler room to one side and the switching room to the other.
		Battersea Power Station was proposed for the Tate Modern but due to financial constraints and less dilapidation, the smaller Bankside building was chosen.

	ASME History and Heritage: Biographies
		In 1867 they patented a water-tube boiler designed to avoid explosions (May 28, 65,042), based on the Wilcox safety water-tube boiler of 1856, and formed the firm of Babcock and Wilcox (incorporated 1881), the first to manufacture water-tube boilers on a large scale.
		He designed and built his water system for Lockport in 1863, receiving a patent for the fire hydrant.
		Her other patents included a machine to fold square-bottomed paper bags (Nov. 15, 1870), machines for shoe cutting (1890-94), several domestic machines, and a compound rotary engine (Dec. 30, 1902) for which she continued to patent improvements.

	STEAM MOTOR VEHICLES - Car - Automobile
		The steam generator, Fig 1, which has been worked out to fulfill these interrelated conditions, is a flash-generator in theory, yet has the appearance of a water-tube boiler and has a water-level in the evaporating zone.
		The water-level is maintained about half-way up the generator by an automatic by-pass valve; this is so arranged that when the regulator tube is filled with steam the by-pass valve is closed by the expansion of the tube, forcing the water from the pumps to lift the check-valve.
		Ten years ago steam cars were in their zenith—not that a large number of makers were producing them, nor yet that the majority of cars were steamers, but rather that a most progressive and prosperous organization was producing these cars on a real quantity basis.

	Misc. Ramblings: Fark Fest
		A separate boiler heats water to generate steam, which is pushed at about four times normal atmospheric pressure through a hollow tube submerged in the water.
		The resulting effect is a dramatic drop in pressure, essentially a vacuum, that sucks water from the front to the back of the tube and thus produces thrust to move.
		When the steam hits the water, it immediately condenses to 1,600th of its previous volume.

	FRIEDRICH GAUERMANN - LoveToKnow Article on FRIEDRICH GAUERMANN
		This gauge therefore consists of a curved or coiled tube of elastic material, and preferably of elliptic section, connected with the boiler and arranged with a multiplying gear so that its bending or unbending actuates a pointer moving over a graduated scale.
		The purpose of the former is to enable the attendant to see whether or not there is a sufficient quantity of water in the boiler.
		If the pressure within the tube is less than that outside it, the tube tends to bend or coil itself up further; with a pointer arranged as before, the gauge then becomes a vacuum gauge, indicating how far the pressure in the vessel to which it is attached is below that of the atmosphere.
