A steam generator on a ship is an auxiliary boiler which draws high-pressure superheated steam from the vessel's propulsion system to generate low pressure saturated steam. This secondary steam is then used to power auxiliary shipboard engines driving winches or pumps, or to meet any steam requirement that does not require superheating, such as
On ships which are not propelled by steam, gas turbine and diesel ships, for example, some type of boiler is still used to provide hotel service steam. There are two such boiler types: Auxiliary boilers are usually smaller, lower pressure versions of propulsion boilers, in which fossil fuels are burned to heat the boiler tubes.

The steam boiler adopts the three return structure combined with the layout of the economizer and air preheater, recycles large quantity of condensing water during the production process. By making full use of waste heat of condensation water, the boiler still can ensure low exhaust temperature.
How to operate auxiliary boiler onboard ship for at least 10 days period when all boiler chemicals are finished. Answer: Pay attention to the measured values of the boiler water quality, when/if the salt concentration increases then blow off from the bottom of the boiler more frequently.
Marine auxiliary boiler HB. HB-025~18 (Actual Evaoration: 2,500~18,000 kg/h) Special Features. Compact design is more space efficient.
Auxiliary boilers on diesel main propulsion ships, other than tankers, are usually of composite form, enabling steam generation using oil firing or the exhaust gases from the diesel engine. With this arrangement the boiler acts as the heat exchanger and raises steam in its own drum.
Auxiliary Boiler on Ships – Marine Engineering. Because of the internal pressure, the flat plates are mutually connected by vertical solid stays. The steam drum is furnished with the necessary internal fittings to ensure an even distribution of the feed water, of the circulation water from the exhaust boiler and to ensure a sufficient dryness of steam.

Repeat the procedure for other safety valve. Ensure no condensate at the drain line. Crack open main steam stop valve, slowly open until its full open.
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.

Auxiliary boiler. A boiler that supplies steam for essential auxiliary purposes but not for main propulsion.
Proper boiler water treatment eliminates sludge and scale deposits within the boiler. However, over along period of time a film of copper and iron oxides build up on the tube surface. Most of these oxides are transported from oxides of corrosion within the feed system to the boiler with the condensate.
Many ships have used an auxiliary steam turbine as a primary pressure reducing stage before passing the steam to other auxiliaries demanding steam at a substantially lower pressure than that available. Such an arrangement gives a heat balance which is far more favourable than that obtained with a pressure reducing valve
