What is a primary function of a boiler on a marine vessel?

The primary function of a boiler on a marine vessel is to produce steam for propulsion and auxiliary systems. Boilers are integral to the overall operation of a ship, particularly those that rely on steam propulsion. They heat water to high temperatures, converting it into steam, which is then used to drive turbines or engines that propel the vessel forward. Additionally, the steam produced can be utilized for other system requirements on board, such as powering auxiliary machinery and providing heat for various processes.

While generating electrical power is critical, that function is typically managed by other systems such as generators powered by engines. Providing heating for living quarters is also an important function, but it is a secondary use of steam in marine operations. Water treatment processes are essential for maintaining the quality of water used in boilers, however, the boiler itself is primarily focused on steam production.
