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.
Definitions Points of Interest Admiralty three-drum boiler: the Royal Navy's standardised pattern of three-drum boiler.; annular fire-tube boiler: a vertical fire-tube boiler with the tubes arranged radially, [1] such as the Robertson.
Diagram of a water-tube boiler. Another way to rapidly produce steam is to feed the water under pressure into a tube or tubes surrounded by the combustion gases. The earliest example of this was developed by Goldsworthy Gurney in the late 1820s for use in steam road carriages. This boiler was ultra-compact and light in weight and this ...
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. Gases and smoke from the furnace pass to the back of the boiler, then return through the small tubes and up and out ...
In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas.In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used.
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 steam-generating tubes.
Schematic diagram of a "locomotive" type fire-tube boiler. In the locomotive-type boiler, fuel is burnt in a firebox to produce hot combustion gases. The firebox is surrounded by a cooling jacket of water connected to the long, cylindrical boiler shell.
The boilermaker trade evolved from industrial blacksmithing; in the early nineteenth century, a boilermaker was called a boilersmith. The involvement of boilermakers in the shipbuilding and engineering industries came about because of the changeover from wood to iron as a construction material. It was often easier, and less expensive, to hire a ...
