Its main purpose is to ensure an even flow of fluid over the entire plate while maximizing heat transfer efficiency and minimizing maldistribution and fouling. This article needs additional citations for verification. In large power plants with steam-driven turbines , shell-and-tube surface condensers are used to condense the exhaust steam exiting the turbine into condensate water which is recycled back to be turned into steam in the steam generator.

Specialized ranges of the gasketed plate-and-frame heat exchanger hea also possible such as our Semi-welded and WideGap. Dismantling and Assembly Procedure 3. This article needs additional citations for verification.
Shell and tube heat exchanger
For bigger models with higher flow rates, reinforcing partition plates are sometimes used which are not shown in the animation.
Tube surfaces from standard to exotic metals with plain or enhanced surface characteristics are widely available. Principle of operation of Shell and Tube Heat Exchangers 2. The physical design anomation the gasketed plate heat exchanger allows easy cleaning, and modification of capacity by the addition or removal of plates.
One Pass Shell 5. U — Tube Bundle 5.
Channel and Removable Cover 5. Shell and tube Heat Exchangers have the ability to transfer large amounts of heat in relatively low cost, servicable designs.
Steam heater GPHE The animation above shows the working principle of an Alfa Laval gasketed plate-and-frame heat exchanger when used as a steam heater. Hydraulic Pressure Testing and related Maintenance details 2. Air Cooled Exchangers 3. Patterned Plate Heat Exchanger 1. Its main purpose is to ensure an even flow of fluid over the entire plate while maximizing heat transfer efficiency and minimizing maldistribution and fouling.
Typically, the ends of each tube are connected to plenums sometimes called water boxes through holes in animatoon. Double Split Flow 5.
Heat Transfer by Shell and Tube Heat Exchangers
Temperature cross is also possible, meaning that the hot outlet can reach a lower temperature than the cold outlet. To be able to transfer heat well, the tube material should have good thermal conductivity. Perry's Chemical Engineers' Handbook 6th ed. Online course access for 60 days.
Video cannot be played.
In a gasketed plate heat exchanger, the plates are fitted with elastomeric gaskets which seal the channels and direct the fluids into alternate channels.
Often multiple heat exchangers can be used to simulate the counter current flow of a single large exchanger.
Rear End Head Type 5.
Pull-Through Floating Head 5. The fluid runs through the heat exchanger in two passes and then leaves through one of the connections in the pressure edchanger. The fluids enter through the connections and portholes of the heat transfer plates.
The content covers the topic to component level detail. In other projects Wikimedia Commons. Bayonet Heat Exchanger 1. Fixed-Tube-Sheet Heat Exchanger 2. There can be many variations on the shell and tube design. Wikimedia Commons has media related to Shell and tube heat exchangers. Floating Head with Backing Device 5.
