Double-ended boilers.
Figs. 37 and 38 show a double- ended boiler. This is a common type for mercantile steamers, and is also fitted in a considerable number of ships of the Royal…
Arrangement And Efficiency Of Boilers – Water Tank Boilers.
Low-pressure boilers. The first boilers fitted to work marine engines were of the rectangular, or 'box' form; an example of this type is shown in Figs. 27 and 28, which…
Quadruple expansion engines.
In many cases in the mercantile marine the stage expansion principle is carried still further, and quadruple expansion engines fitted, dividing the expansion into four stages, the boiler pressures being…
Triple expansion engines.
With initial steam pressures above 100 lbs. per square inch, the variation of temperature in each cylinder of an ordinary compound engine again becomes great, so that the full economy…
Vertical (compound) engines.
The vertical type of engine, with cylinders at the top and crank-shaft below, was adopted for merchant ships long before it was introduced into the Royal Navy, because it was…
Early screw engines.
The majority of steamers, both war and mercantile, built during the years 1850-60, were fitted with horizontal screw propeller engines worked with steam of from 20 to 25 lbs. pressure…
Return connecting-rod engines.
This kind of engine was adopted by the majority of marine engineering firms to enable the horizontal cylinders to be brought close to the crank-shaft, and, as usually fitted, is…
Gearing for screw engines and its abandonment
In order to attain the same speed of ship the screw propeller had to be driven at a much greater speed than the paddle-wheel, and as it was not possible…
