Air Cooler Section
|
A section of tubes, located above the air exit lane in a condenser, that condenses nearly all of the steam in the steam-air mixture flowing through the air exit lane
|
|
Air enjectors
|
Jet pumps that use high velocity fluid flow to create a vacuum
|
|
Air exit lane
|
A low pressure area in the center of the tube sections of a condenser. The low pressure causes the steam-air mixture and through the tubes in the air cooler section.
|
|
Air flow meter
|
A meter that indicates the amount of air being removed fromt he condenser shell through the outlet piping
|
|
Air removal system
|
A system that removes air and non- condesalbe gases and maintains the vacuum created by the volume reduction of condensing steam:also used to establish a normal vacuum in a condenser prior to turbine startup
|
|
Auxillary steam
|
Stem used for puposes other than driving a main turbine or heating feedwater: typicallyh used in makeup water perification systems, steam tracing lines, and turbine-driven boiler feed pumps.
|
|
Backwashing
|
A means of removing any blockage from tube sheets by reversing the flow of circulating water through the sheets.
|
|
Backwash system
|
A system used to remove blockage from the circulating water stuble and thus help in maintaining proper condenser vacuum
|
|
Balancing drum
|
A piston mounted on the shaft inside a chamber at one end of a multi-stage pump and used to reduce axial thrust; created byu the spinning impleers; oftem referred to as a balancing piston
|
|
Balancing drum leakoff
|
A flow created by a pressure differential in a balancing line; insures that the pressure across the balancing drum will not equalize
|
|
Basket strainer
|
A strainer used to filter out large amounts of impurities from fluid in a piping system that is subject to larg buildups of impurities
|
|
Boiler feed pump
|
A pump that functions to increase the pressure of feedwater to a value high enough to move it through the components of the feedwater system and into the boiler
|
|
Boiler stop valves
|
Valves used to isolate the boiler from the rest of the system, if needed
|
|
Butterfly balve
|
Valves used to isolate the boiler from the rest of the system.
|
|
Cascading drain system
|
A drain system associated with feedwater heaters in a string arrangment. The pressure differntial from one heater to the next causes the drips to flow from one heater to another
