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 ...
Municipal water feed; Fluid from water storage tank to external (passive) heat source; passive heat source can be the ground (soil or groundwater), sun or air via heat pump, district heating or thermodynamic solar panel; Fluid from heat pump, or thermodynamic solar panel to water storage tank; Pump, actuator, controller and other parts; Water ...
The water is reused and needs to be treated to continue efficient operations. Boiler water must be treated in order to be proficient in producing steam. Boiler water is treated to prevent scaling, corrosion, foaming, and priming. Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range.
The water may be freshly supplied or returning condensate produced as a result of the condensation of the steam produced by the boiler. These pumps are normally high pressure units that take suction from a condensate return system and can be of the centrifugal pump type or positive displacement type.
The typical steam turbine used in the aux feedwater systems are the “solid wheel” or “water wheel” Terry Steam Turbines manufactured by the Curtiss-Wright Corporation in Summerville, SC. In contrast to emergency core cooling systems for loss-of-coolant accidents , the auxiliary feedwater system does not inject directly into the reactor ...
In a water tube boiler, the water is recirculated inside until the vapor pressure of the water overcomes the vapor pressure inside the stream drum and becomes saturated steam. The forced circulation boiler begins the same as a natural circulation boiler, at the feed water pump. Water is introduced into the steam drum and is circulated around ...
