Abstract

ABSTRACTOver a decade ago, a commitment was made to the concept of using boilers to recover waste heat from naval gas turbine generators to provide energy in the form of steam for fresh water production, water heating, fuel heating, galley and laundry services. In meeting the challenge to interface an auxiliary steam generating system with the ship's vital electrical supply, the following design and service problems must be addressed without compromising the ship's generators. Gas Side Pressure Drop Gas Side Fouling Waterside Corrosion and Deposits Exhaust Gas Leakage Dry Operation “Hot Start” from Dry Condition Moisture in Steam Stability of Pressure and Water Level Access for Maintenance Frequency and Complexity of Required Maintenance This paper discusses specific design features of the CG‐47 Class Waste Heat Boilers and the Integration of state‐of‐the‐art steam system components into a package of equipment that meets the design and operational requirements listed above.
