An auxiliary boiler is a small boiler that supplies steam for distilling plants, space heating, oil heating, water heating, galley, and laundry. These boilers have all the auxiliaries, accessories, and controls to form a unit assembly. They are arranged to operate as complete self-contained, steam-generating plants. For further information on auxiliary boilers, refer to Naval Ships' Technical Manual, S9086-GY-STM-000, chapter 221, section 5.

WASTE-HEAT BOILERS

On some classes of ships, you may find wasteheat boilers. Waste-heat boilers are used by the Spruance class and Ticonderoga class CGs. These boilers supply the steam for ship's services by using the hot exhaust gases from the gas turbine generator sets (GTGSs). For further information on waste-heat boilers, refer to GSM 3 & 2, NAVEDTRA 10548-2, chapter 6.

SUMMARY

In this chapter we have discussed boiler terminology, construction, types, components, and function. To help you understand this information, go down to the fireroom on your ship and ask a BT to show and explain to you the things you have just read about. This should help your retention of the information you have studied and perhaps provide you with additional knowledge on boilers.
