A package boiler is a factory-made boiler. Package boilers are available in a range of standard designs. Package boilers are used for heating and act as a steam generator for small power purposes such as self-powered industrial plants. Package boilers are low pressure designs. A low pressure means low temperature water in the heat exchanger.
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.
donkey boiler: A donkey boiler is used to supply non-essential steam to a ship for 'hotel' services such as heating or lighting when the main boilers are not in steam, for example, when in port. [3] Donkey boilers were also used by the last sailing ships for working winches and anchor capstans. See also auxiliary 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 down, neither heating nor domestic hot water are available. Air convection heating systems have been in use for over a century.
This committee put in the form work for the first edition of the ASME Boiler Code - Rules for the Construction of Stationary Boilers and for the Allowable Working Pressures, which was issued in 1914 and published in 1915. [5] The first edition of the Boiler and Pressure Vessel Code, known as the 1914 edition, was a single 114-page volume.
erosion of a boiler's plates from the internal water space, particularly where there is a step inside the shell. This was a problem for early boilers made from lapped plates rather than butted plates, and gave rise to many boiler explosions. In later years it was a problem for the non-circular water drums of Yarrow boilers. Handhole
A "Scotch" marine boiler (or simply Scotch boiler) is a design of steam boiler best known for its use on ships. Sectional diagram of a "wet back" boiler. The general layout is that of a squat horizontal cylinder. One or more large cylindrical furnaces are in the lower part of the boiler shell. Above this are many small-diameter fire-tubes ...
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.
