The design was based around two factors that, along with excellent water circulation, should be appropriate cooling even at light loads. Its special feature is its Monocoque body i.e. the unheated downcomers form the supporting frame work [2] and not the thermally loaded tubes, hence the name corner tube boiler. [1]
The only railway use of water-tube boilers in any numbers was the Brotan boiler, invented by Johann Brotan in Austria in 1902, and found in rare examples throughout Europe, although Hungary was a keen user and had around 1,000 of them. Like the Baldwin, it combined a water-tube firebox with a fire-tube barrel.
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, [1] [page needed] [2] [page needed] including water heating, central heating, boiler-based power generation, cooking, and sanitation.
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.
Electrode boilers can work on both single-phase and three-phase supplies. If DC voltage is used, electrolysis of water occurs, decomposing water into its elements H 2 at the cathode (negative electrode) and O 2 at the anode (positive electrode). The electrode boiler is 99.9% efficient with almost all the energy consumed producing steam. [1]
Boiler steam drum. Three drum/four drum boilers – are the veterans of the normal day boilers, although they are still used in some industries. Bi drum boiler – are used for power generation and steam generation both. For power generation they are used now seldom and are replaced by single drum boilers as the bi drum boilers are non-reheat ...
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.
From Brown Boveri Review [3]. The Velox principle combines the use of combustion under pressure, with very high flue gas velocities and with a gas turbine, whereby the pressure in the combustion chamber, the high gas velocities and the pressure drop of the gases for production of work are created by means of a compressor driven by the gas turbine, the latter being actuated by the products of ...
