... temperatures are normally in the range of 560 to 600 °C (1040 to 1110 °F) and the pressure is about 45 bar (0.65 ksi). Low-pressure steam leaving the turbine, which is a little above its boiling point, enters the condenser, where it condenses back to water. A condenser is a shell-and-tube-type heat...

... there is no question of sludge removal by blowdown. Also, there is no carryover of solids. The main drawback of AVT is its lack of buffering capacity. For instance, if a condenser tube leaks or there is some other contamination of a similar nature, the alkalinity or pH of water drops quickly, promoting corrosion...
