Steam on Deck and Steam Boilers on Ships

Ships boilers produce steam for engineroom but also to supply the accommodation and deck. This steam is produced by the boilers can be at very high pressure and temperature and, in some cases being superheated. This necessates the use of pressure reducing valves and a desuperheater, are all normally situated in the engineroom or boiler room.

Backup steam supply is critical for Calpine

In normal operation, either a dip in header pressure or a GT trip will cause the auxiliary boilers to “fire out,” according to Bagley. Once the steam header is stable and the plant is stable from the GT trip, the duct burners on the operating GT will be fired out and the auxiliary boilers returned to hot standby.


than 100 Ibm/hr of steam to utility boilers in excess of 10 million Ibm/hr. The focus here will be on boilers sized in between these two extremes, which is also where there is the greatest diversity of design. In order of increasing capacity, three boiler types are the fire-tube, water-tube and waterwall boilers.

Auxiliary boilers are usually smaller, lower pressure versions of propulsion boilers, in which fossil fuels are burned to heat the boiler tubes. The LSD-41 and AOE-6 class ships are examples of ships which use auxiliary boilers. These boilers consist essentially of a steam drum and a water drum which are connected by a bank of generating tubes.

Boiler (power generation)

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
