Fire-tube boiler - WikipediaThe horizontal fire-tube boiler is also typical of marine applications, using the Scotch boiler; thus, these boilers are commonly referred to as "scotch-marine" or "marine" type boilers. Vertical boilers have also been built of the multiple fire-tube type, although these are comparatively rare; most vertical boilers were either flued, or with cross water-tubes.SHIPS SHIPS HEAT GENERATION PLANTHEAT GENERATION PLANTHEAT GENERATION …precipitates are left behind in the boiler water - they do not travel with the steam. If they are allowed to accumulate, they will settle out as scale on the boiler metal. This is what happens when water in a pan on the stove is allowed to boil dry, or

22/8/2019 · The most important aspect of any marine boiler is maintaining the correct water level. As the boiler fires, steam liberates from the surface of the water and thus as the steam gets consumed, there is subsequent drop in water level inside the boiler. Steam gets produced only when there is an effective circulation of water within the boiler.

The boiler is a closed vessel in which the water is stored. Hot gases are produced by burning fuel in the furnace. These hot gases are made to come in contact with the water vessel where the heat transfer takes place between the water and the steam. Therefore, the basic principle of the boiler is to convert water into steam by using heat energy.
