Condenser Vacuum - an overview | ScienceDirect Topics

Steam sparging in the condenser hotwell complements the use of auxiliary boiler and condenser vacuum pumps to degasify condensate in hotwells during short-term shutdown and to more rapidly degasify during ramp-up, ramp-down, and part-load operation.. Use of pre-coat condensate treatment system (using either cellulose filter medium or powdered ion exchange resin) may be justified in terms of

Troubleshooting Steam Surface Condensers

2012-9-15 · Condenser Vacuum Pumps Condensers are provided with vacuum pumps/ejectors The condenser creates the vacuum, NOT the vacuum pump Vacuum pumps are there to extract air and pump it up to atmospheric pressure A startup ejector ("hogger") is provided to create a rough vacuum in order to start the turbine Condenser Venting

Boiler Waterwall Tubes and Condenser Tube Leakage

2020-12-17 · Tube failures are a cause of concern in boiler outage, contaminating boiler feed water due to condenser leakage leads to a large amount of damage. Condensers using brackish water for cooling in high pressure boilers will have to be maintained well to avoid any leakage of condenser tubes. Any leakage of condenser cooling water to the condensate leads to low pH levels in boiler water, which

Why do we create a vacuum in a steam turbine

Question: Why do we create a vacuum in a steam turbine condenser? Let me take two minutes to explain from rankine cycle. It is known that "The Rankine cycle" is the fundamental operating cycle of all thermal power plants where an operating fluid i

Effect in Steam Turbine Due to High Vaccum in

2011-2-15 · Condenser vacuum should be maintained as close to 29 inches Hg as practical. This allows maximum expansion of the steam, and therefore, the maximum work. decreases the operating efficiency of the plant because the sub-cooled condensate must be reheated in the boiler, which in turn requires more heat from the reactor, fossil fuel, or other

What is Vacuum Steam? | TLV - A Steam Specialist

2019-6-3 · Vacuum steam is the general term used for saturated steam at temperatures below 100°C. As briefly discussed in Principal Applications for Steam, both positive pressure steam and vacuum steam can be used in heating processes.The following article will discuss the properties of vacuum steam and its advantages over heating with hot water.
