2. Feedwater heater - Wikipedia

   en.wikipedia.org/wiki/Feedwater_heater

   A Rankine cycle with two steam turbines and a single open feedwater heater. A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. [1] [2] [3] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system ...

   en.wikipedia.org/wiki/Rankine_cycle

   These heaters do not mix the input steam and condensate, function as an ordinary tubular heat exchanger, and are named "closed feedwater heaters". Regeneration increases the cycle heat input temperature by eliminating the addition of heat from the boiler/fuel source at the relatively low feedwater temperatures that would exist without ...

   British 9F 92024 with Crosti boiler, showing secondary smokebox door and side-mounted chimney Schematic diagram of a Franco–Crosti boiler with single feedwater heater. The Franco–Crosti boiler is a type of boiler used for steam locomotives.

6. Boiler feedwater - Wikipedia

   en.wikipedia.org/wiki/Boiler_feedwater

   Boiler feedwater is the water which is supplied to a boiler. 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.

7. Boiler - Wikipedia

   Feedwater check valve or clack valve: A non-return stop valve in the feedwater line. This may be fitted to the side of the boiler, just below the water level, or to the top of the boiler. [13] Top feed: In this design for feedwater injection, the water is fed to the top of the boiler. This can reduce boiler fatigue caused by thermal stress.
