Vertical fire-tube boiler, as used in a Leyland steam wagon. A vertical fire-tube boiler or vertical multitubular boiler is a vertical boiler where the heating surface is composed of multiple small fire-tubes, arranged vertically. [1] These boilers were not common, owing to drawbacks with excessive wear in service.
Worcester's gas, oil and LPG ranges consist of regular boilers, combination boilers and system boilers; these are wall-hung, floor-standing or externally sited. Worcester's solar water heating range was released in 2005, with the ground source heat pump range being released in 2007 and the air source heat pump range being released in 2008. [10]
Where such a boiler may be heated either by the exhaust gases of the main propulsion plant, or else separately fired when in port (usually by oil rather than coal) it is referred to as a composite boiler. [4] The boiler is a cylindrical vertical water drum with a hemispherical domed top. This domed shape is strong enough not to require staying.
A vertical boiler is a type of fire-tube or water-tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation. Vertical boilers were used for a variety of steam -powered vehicles and other mobile machines, including early steam locomotives .
The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes ...
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.
Many ship systems, from steam winches and cranes through to domestic heating and the heating of bunker oil as a fuel oil, use steam, produced by such an auxiliary boiler. One rare use of the thimble tube boiler as a directly fired power generator was an experiment fitting to Leyland steam wagons in 1920.
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.
