An O-type boiler is a form of water-tube boiler. It is named, like the D-type and A-type boilers , from the approximate shape of its tubes. They are characterised by single steam and water drums vertically above each other, with curved vertical water tubes to the sides forming an overall cylindrical volume.
A LaMont boiler is a type of forced circulation water-tube boiler [1] in which the boiler water is circulated through an external pump through long closely spaced tubes of small diameter. The mechanical pump is employed in order to have an adequate and positive circulation in steam and hot water boilers.
Schematic diagram of a marine-type watertube boiler. A high pressure watertube boiler [1] (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by fire. Fuel is burned inside the furnace, creating hot gas which boils water in the
du Temple boiler: An early naval water-tube boiler, patented in 1876. [6] [9] [20] Dublin "economic" boiler: a vertical multitubular return fire-tube design, for model engineering-scale uses. [21] Dürr boiler An early naval water-tube boiler, developed and mostly used in Germany, but also trialled in the British HMS Medusa (1888) [22]
In 2013, underwear maker Jockey International offered a new way to measure bra and cup size. It introduced a system with ten cup sizes per band size that are numbered and not lettered, designated as 1–36, 2–36 etc. The company developed the system over eight years, during which they scanned and measured the breasts and torsos of 800 women.
Sections of a steam locomotive showing the many fire-tubes which carry the hot gases of the fire through the boiler to heat the water and so create steam. Boiler design is the process of designing boilers used for various purposes. The main function of a boiler is to heat water to generate steam. Steam produced in a boiler can be used for a ...
If the distribution is through hot water (or other fluid) or through steam, then the furnace is more commonly called a boiler. One advantage of a boiler is that the furnace can provide hot water for bathing and washing dishes, rather than requiring a separate water heater. One disadvantage to this type of application is when the boiler breaks ...
Internal layout of a three-pass fire-tube boiler. Package boilers are commonly called water or fire tube Boilers. Water tube boilers use convection heating, which draws the heat from the fire source, and passes against the generating tubes of the boiler, causing water inside those tubes to boil off into steam.
