On ships using steam propulsion, boilers produce steam that is used by various components. The steam that goes to the main engines, ship's service turbine generators, boiler internal desuperheater and main feed pumps (on certain ships) is called main steam. Steam generation in a conventional steam plant begins with the boiler.
