	Boiler - LoveToKnow 1911
		BOILER, a vessel in which water or other liquid is heated to the boiling point; specifically, the apparatus by which steam is produced from water, as one step in the process whereby the potential energy of coal or other fuel is converted into mechanical work by means of the steam-engine.
		Boilers of the latter kind must all possess certain essential features, whilst of other qualities that are desirable some may not be altogether compatible with the special conditions under which the boilers are to be worked.
		It is essential that the condition of the boiler at the conclusion of the test should be precisely the same as at the commencement, both as regards the quantity of unconsumed coals on the fire-grate and the quantity of water and the steam-pressure in the boiler.

	New Jersey Scuba Diver - Artifacts & Shipwrecks - Boilers
		The boiler is often the last part of a wreck to succumb to the destructive power of the sea.
		Known as "donkey boilers", and usually mounted near the bow of the vessel, these were used to power steam winches and other equipment on the vessel, replacing manpower for tasks such as raising the anchor.
		Boilers on nineteenth-century wrecks such as the Delaware tend to be collapsed or caved in, exposing the fire tubes and other interior components.

	ITP Energy Matters: Boiler Blowdown Energy Recovery (Site not responding. Last check: )
		Measuring the amount of boiler blowdown is essential to determining the magnitude of the loss and the savings potential associated with recovering the energy resident in the blowdown stream.
		Evaluating the boiler blowdown rate based on chemical analysis is based on a mass balance of a chemical component entering the boiler with the feedwater.
		Therefore, the ratio of the concentration of the chemical entering in the feedwater flow divided by the concentration of the chemical exiting the boiler in the blowdown stream is a measure of the blowdown rate, or fraction of feedwater flow.

	Boiler Text
		A boiler is a closed vessel in which water under pressure is transformed into steam by the application of heat.
		In the boiler furnace, the chemical energy in the fuel is converted into heat, and it is the function of the boiler to transfer this heat to the contained water in the most efficient manner.
		Because boiler systems are constructed primarily of carbon steel and the heat transfer medium is water, the potential for corrosion is high.

	Coal Bottom Ash/Boiler Slag - Material Description
		Wet-bottom boiler slag is a term that describes the molten condition of the ash as it is drawn from the bottom of the slag-tap or cyclone furnaces.
		Boiler slag is essentially a coarse to medium sand with 90 to 100 percent passing a 4.75 mm (No. 4) sieve, 40 to 60 percent passing a 2.0 mm (No. 10) sieve, 10 percent or less passing a 0.42 mm (No. 40) sieve, and 5 percent or less passing a 0.075 mm (No. 200) sieve.
		The composition of the bottom ash or boiler slag particles is controlled primarily by the source of the coal and not by the type of furnace.

	Boiler General
		The boiler body itself is a pressure vessel containing the fluid which is to be heated or physically altered.
		The heat transfer tubes of the watertube boiler vary across the circumferential span of the drums: there may be eleven or more differing tube types to assemble in a single watertube unit.
		Interior to the boiler tubes is the fluid medium to be heated or physically altered; thus the name "watertube".

	BOILER
		In the boiler or steam generating unit water is heated to the saturated liquid state, vaporized to the saturated Vapor State, and superheated.
		In the boiler heat is transferred through Radiation from the fire and firebox liner to the tubes directly exposed to the fire, by convection from the hot burnt gasses, and by conduction within the tubes and support structure and again by convection from the tubes to the water.
		The key to designing a better monotube boiler is understanding the basic principals governing heat transfer within the boiler, the hydrostatic back pressure developed within the tube, and the proper combustion of the fuel.

		of the condensed steam that is returning to the boiler, this requires a blended chemical of amines that are fed into the boiler.
		These particles are great insulators that inhibit heat exchange and cause the boiler to lose heat tranfer, therefore even a small loss of boiler efficiency can result in substantial increases in fuel consumption.
		A 50 hp boiler producing steam at a rate of 1.7 million Btu/hr at 75% efficiency, and operating for 5040hrs/year (7 month Winnipeg heating Season) requires an energy input of 1.7 million Btu/hr x 5040 hrs/yr.

	What is a high efficiency condensing boiler?
		A high efficiency condensing boiler works on the principle of recovering as much as possible of the waste heat which is normally rejected to the atmosphere from the flue of a conventional (non-condensing) boiler.
		When in condensing mode (for condensing boilers do not condense all the time) the flue gases give up their 'latent heat' which is then recovered by the heat exchanger within the boiler.
		By law most new gas boilers fitted in England and Wales must now be high efficiency condensing boilers (with a few exceptions depending on suitability). High efficiency condensing boilers can be easily fitted to most new and old heating systems, ask your installer for more details.

	boiler. The Columbia Encyclopedia, Sixth Edition. 2001-05
		In some large installations the incoming air is preheated by the waste heat of the flue gases, and in order to increase the speed of combustion a forced draft (air at higher than atmospheric pressure) is often used.
		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.
		The construction of boilers in the United States is governed by the American Society of Mechanical Engineers’ Boiler Construction Code.

	Determination of Boiler Carry-over
		It is a measure of the separation efficiency of the boiler for a specific load, drum level, and boiler water chemistry conditions.
		The degree of vaporous carry-over is expressed as a distribution ratio, which is the ratio of the concentration of a specific molecular compound in the steam to its concentration in the liquid water.
		For drum boilers on all-volatile treatment (AVT) and oxygenated treatment (OT), the concentration of sodium in steam may be less than the analytical detection limit and, for a carry-over test, a sodium compound, such as Na, may have to be added to the boiler water.
