Steam-Steam Generators-

Found on steam propulsion plant and used for the production of low pressure steam for tank heating purposes. The heating steam circuit may be separated from the main system to reduce the risk of oil contamination in the main boilers
Generally the heating steam is supplied from the Intermediate Pressure system. Under sea conditions there is sufficient exhaust steam capacity to supply the IP system requirements. In separated duty , live HP steam may be separated and pressure reduced as make up..
