A steam generator on a ship is an auxiliary boiler which draws high-pressure superheated steam from the vessel's propulsion system [1] to generate low pressure saturated steam. This secondary steam is then used to power auxiliary shipboard engines driving winches or pumps, or to meet any steam requirement that does not require superheating ...
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 ...
Vessels typically contained several engines for different purposes. Main, or propulsion engines are used to turn the ship's propeller and move the ship through the water. . The fire room got its name from the days when ships burned coal to heat steam to drive the steam engines or turbines; the room was where the stokers spent their days shoveling coal continuously onto the grates under the ...
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.
Three-drum boiler, casing removed. Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary ...
When the officer in charge on ship's bridge orders an increased bell, the steam turbine power output is demanded, using more steam and requiring an increased feed rate. This draws more water from the condenser, potentially to the point of going dry and starving the boiler or steam generator resulting in a loss of propulsion. This is until the ...
Main engine deck of a cargo vessel Location of a ship's engine room on a bulk carrier Engine room of the Mercy Ship Caribbean Mercy in 1997. Her propulsion diesel is an MAK. EMD diesels in the engine room of the Research Vessel Davidson circa 2002. On a ship, the engine room (ER) [1] is the compartment where the machinery for marine propulsion ...
The first Yarrow boilers were intended for small destroyers and filled the entire width of the hull. In the early classes, three boilers were used arranged in tandem, each with a separate funnel. The later sets supplied for capital ships used multiple boilers and these were often grouped into sets of three, sharing an uptake.
