Anyone knows how to place the DERESONATING BAFFLES in a Shell and Tube heat Exchanger? How does it look likes?
croghan27 said:I am sure some engineer can locate the areas that are most prone to resonating, or even just someone with a stethescope - that is the place for the interiour baffles ... the ones I am familiar with lie within and to parallel the tube bundle.
I have also seen anti-swurrl (is that a word?) baffles placed near the tube inlet and outlets. If they are within the bundle they have to be removed for maintenence on the tube sheets etc - if inside the piping leading to the exchanger, not.
Other than that - differences in flow and pressure on the shellside can make a big difference.
A shell and tube heat exchanger is a type of heat transfer device used to transfer thermal energy between two different fluids. It consists of a series of tubes enclosed within a cylindrical shell. One fluid flows through the tubes while the other flows through the space surrounding the tubes, allowing for heat to be exchanged between the two fluids.
In a shell and tube heat exchanger, one fluid flows through the tubes, while the other flows through the shell. The tubes are typically made of a highly conductive material, such as copper or stainless steel, and are designed to increase the surface area available for heat transfer. As the fluids flow through the tubes and shell, heat is transferred from the warmer fluid to the cooler fluid, resulting in a temperature change in both fluids.
Shell and tube heat exchangers have several advantages, including high heat transfer efficiency, compact size, and versatility in handling a wide range of operating conditions and fluid types. They are also relatively easy to maintain and can be designed for high-pressure and high-temperature applications.
Shell and tube heat exchangers are commonly used in industries such as chemical, oil and gas, power generation, and HVAC. They are often used for heating or cooling processes, such as in refrigeration systems, heat recovery systems, and air conditioning systems. They are also used for heat transfer in various industrial processes, such as food and beverage processing, pharmaceutical production, and wastewater treatment.
When selecting a shell and tube heat exchanger, factors such as the type and properties of the fluids, desired temperature change, flow rates, pressure and temperature ratings, and space constraints should be considered. It is important to consult with a heat exchanger expert to determine the most suitable design and materials for your specific application.
