Nuclear Power Plant Condensate-Feedwater Systems

The Feedwater Pump increases the water pressure from about 350 pounds per square inch (psi) to about 1200 pounds per square inch. Each unit typically will have 2 or 3 Feedwater pumps. The feedpumps may be electrically or turbine-driven. For the pump ...

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.[4] This reduces plant operating costs and also helps to avoid thermal shock ...

Boiler feedwater

 · 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. From this tank it ...

Boiler feedwater pump

A boiler feedwater pump is a specific type of pump used to pump feedwater into a steam boiler. 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 ...

Characteristics of boiler feedwater

Composition that boiler feedwater should have depending on boiler working pressure Water absorbs more heat for a given temperature rise than any other common inorganic substance. It expands 1600 times as it evaporates to form steam at atmospheric pressure.

Boiler – Fundamentals and Best Practices

Steam Production When heat is added to water, its temperature rises at a rate of 0.56 C (1 F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0 C (32 F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100 C

Boiler Feed Water Pump Working Principle and Operation

To ensure adequate feedwater flow a boiler must have at all times a slightly higher capacity for feedwater than for steam generation capacity of boiler. This pump is fitted with mechanical seal or labyrinth glands to prevent leakage along the shaft and a balance piston to achieve hydraulic balance and balancing line from first stage to last stage to accumulate the thrust in feed water pump.
