2022/1/7 · Boiler types. The watertube boiler is employed for high-pressure, high-temperature, high-capacity steam applications, e.g. providing steam for main propulsion turbines or cargo pump turbines. Firetube boilers are used for auxiliary purposes to provide smaller quantities of low-pressure steam on diesel engine powered ships.

Fire-tube boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. Fire-tube boilers, typically have a lower initial cost, are more fuel-efficient, and are easier to operate. Their capacities are up to 25tons/hr and 17.5 kg/ cm2.

Boiler. In the boiler, heat is added to liquid water to generate steam at a certain pressure. Boiler pressure is used to control the thermal capacity of the steam and to motivate the steam through the system. Steam Header. Steam exits the boiler through piping referred to as the steam header. The header also serves as a reservoir that feeds
