www.geappliances.comSUPERHEATED WATER Microwaved water and other liquids do not always bubble when they reach the boiling point. They can actually get superheated and not bubble at all. Superheated liquid will bubble up out of the cup when it is moved or when something like a spoon or tea bag is put into it. To prevent this from happening and causing injury, do ...

Both the hexane vapor from the flash/vacuum desolventizer and the hexane and steam vapors from the stripper are directed to a condenser. From the condenser, hexane vapors pass to the mineral
DESIGNING STEAM JET VACUUM SYSTEMS
www.graham-mfg.comThe steam should be dry and saturated, unless the system specifi-cations call for superheated steam. To maintain the optimum velocity, and avoid excessive heat loss and pressure drop, all insu-lated steam lines should be sized to match the connections on the ejectors. For dry steam, the inlet line should be taken off the top of main steam header.

www.cpp.eduIf the steam enters as a superheated vapor, it does not condense significantly in the turbine. If the steam is saturated as it enters the turbine, a significant of liquid is formed which causes erosion and wear of the turbine blades. Process 2-3: The steam enters the condenser and exits in state 3 as saturated liquid water.

eng.sut.ac.thA piston–cylinder device initially contains steam at 3.5 MPa, superheated by 5°C. Now, steam loses heat to the surroundings and the piston moves down hitting a set of stops at which point the cylinder contains saturated liquid water. The cooling continues until the cylinder contains water at 200°C. Determine (a) the initial temperature,
