Boiler feedwater is an essential part of boiler operations. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used it is then dumped to the main condenser. From the condenser it is then pumped to the deaerated feed tank.
Waste heat boilers use heat that would otherwise be wasted by exhausting into the atmosphere to heat water and make steam. For example, DD 963, DDG 993, and CG 47 class ships use exhausted combustion gases from gas turbine generators to provide a heat source for waste heat boilers.
