For example if a ship is a steam powered ship, two or more boilers will be provided to produce high temperature, high pressure steam. If a ship is carrying a diesel engine as the main propulsion system, one or two smaller boilers are used for running various ship's machinery and services.he design and arrangement of both the types is just the opposite. In water tube boilers, the feed water passes through the tubes and the hot gases are made to pass over them, while in fire tube boilers, the hot gases passes through the tubes and the feed water surrounds them.
