leaks, the condenser often does not get the attention it deserves. Many of the corrosion problems in fossil fuel boilers, LP steam turbines and feedwater heaters have been traced to leaking condensers. Tube leaks allow the ingress of cooling water into the steam-water cycle. The very nature of the condenser tends to increase a problem with cooling
Jan 15, 2015 · When a vacuum leak occurs in the condenser, noncondensable gases are introduced and must be vented. The gases increase the operating pressure, thereby reducing the turbine output and efficiency. The gases also decrease the heat transfer of the steam to the coolant and can cause corrosion in the generator.
Key Condenser Failure Mechanisms Power EngineeringApr 01, 2009 · Air enters a steam-generating system at points around the condenser due to the strong vacuum generated within. Prime spots for in-leakage include the expansion joint between the turbine
Jul 31, 2021 · There is an off-gas treatment system, as well as a reactor water filtering system, that endeavors to filter the various nuclides out of the water. As was mentioned, condenser tube failures are at a lower pressure than the outside cooling water, so leakage is into the condenser, and undesirable contamination can and does occur.
Power plant and calculations:STEAM CONDENSER,VACUUM May 10, 2020 · Example-4:The air leakage into the steam condenser is 0.721 kg/min.The vacuum near the outlet of ejector is 690 mm of Hg when the barometer reads 760 mm of Hg & temp.at this point is 20 deg c..Calculate the mass of steam condensed. Solution:Pressure in the condenser
May 27, 2020 · Following are the major effects due to air leakage into condenser: As there is a pressure difference between these two and turbine steam condenser. U loop is around 2.5 to 3 meter, it depends on pressure difference between 1 st stage and steam condenser. If there is pressure difference of 0.25 kg/cm2 between 1st stage and steam condenser
Steam Condenser:Basics, Parts, Advantages, and Jun 08, 2021 · A steam condenser is a mechanical device employed to condense exhaust steam at the turbine into the water. It conducts this process with the help of cooling water that circulates inside it from the cooling tower. The pressure within a steam condenser is held below the atmospheric pressure to enhance efficiency.
Sep 01, 2010 · When half of the condenser can be safely isolated while the unit is running (or at least while there is still vacuum on the condenser) any number of methods have been tried to find condenser
Taming Condenser Tube Leaks, Part IIOct 01, 2010 · Taming Condenser Tube Leaks, Part II. In Part I of this two-part report we examined the various chemical forces at work in condenser tube leaks, the steam plant components placed at
Apr 01, 1995 · The most-common causes of condenser inefficiency are:microbiological growth on the water side, scale formation on the water side, tube pluggage by debris and air in-leakage on the steam side. These problems can cost a plant dearly. Well-planned treatment programs to combat these causes, however, pay for themselves many times over. The paper discusses these four types of fouling and
