Floating
Head Condenser |
U-Tube Heat
Exchanger |
BEST USE |
Any, particularly good for cycling loads and poor quality
cooling water |
Best for steady loads and fair-good quality cooling
water |
TUBE CLEANING |
Flushing, chemical and mechanical brushing are all possible |
Flushing and chemical only. Brushing limited to straight
portion of tube |
THERMAL CYCLING |
Straight, equal length tubes share stresses evenly |
Highest stresses on shortest tubes with tightest bends |
STEAM FLOWS |
Optimum flow and heat transfer with good baffle design |
Design relies on open space to dissipate and distribute
flows |
HEAT TRANSFER |
Larger shell diameter means lower steam velocities,
which improve heat transfer |
Smaller, longer shells reduce heat transfer rates and
increase installed and bundle removal space |
