What is the function of a baffle?
The main roles of a baffle in a shell and tube heat exchanger are to: Hold tubes in position (preventing sagging), both in production and operation.
Prevent the effects of steam starvation, which is increased with both fluid velocity and the length of the exchanger.
Direct shell-side fluid flow along tube field..
What is the purpose of baffles in heat exchanger?
Baffles also serve as support s for the tubes during operation and help in preventing vibration from flow induced eddies. Although heat transfer is increased through the baffle arrangement, the pressure drop of the shell side fluid is also increased due to the decreased flow area, leakage and bypass effects.
What is baffle?
(Entry 1 of 2) transitive verb. 1 : to defeat or check (someone) by confusing or puzzling : to confuse or frustrate completely : disconcert Her behavior baffled her parents. 2 : to check or break the force or flow of by or as if by a baffle (see baffle entry 2) baffle the steam.
What is baffle cut?
Baffle is provided with a cut (%) which is expressed as the percentage of the segment height to shell inside diameter. In general, baffle cut can vary between 15% and 45% of the shell inside diameter. This cut allows the fluid to pass through in parallel or counter flow direction.
How do you calculate baffle spacing?
number of baffles can then be calculated by = ( tube length/baffle spacing ) – 1. However this formula assumes that inlet and outlet spacing are same as central spacing. However this may or may not be optimum baffle spacing.
What are the two types of heat exchangers?
What Are The Different Types Of Heat Exchanger?Finned Tube Heat Exchanger Or Air Cooled Heat Exchanger. Suitable for: air/gas to fluid. … Shell And Tube Heat Exchanger. Suitable for: fluid to fluid / fluid to gas. … Plate Heat Exchanger Or Gasket Plate Heat Exchanger. Suitable for: fluid to fluid / fluid to vapour.
What is difference between condenser and heat exchanger?
While a heat exchanger can regulate process temperatures independently, a condenser is a component of a chiller system (water-cooled or air-cooled) which functions to remove heat generated by an industrial or commercial process.
What is the function of baffles in hydraulic system?
Baffles work to efficiently separate the return flow from the inlet flow. Additionally, baffles help the reservoir fluid circulate which promotes heat dissipation from the fluid.
What is baffle spacing?
Baffle spacing is one of the most important parameters used in the design of shell and tube heat exchangers. Closer spacing causes a higher heat transfer rate and pressure drop. On the other hand, a higher baffle spacing reduces both the heat transfer rate and pressure drop .
How do Baffle plates work?
What does a baffle plate do? The simplest way to describe a baffle plate, which is placed at the top of the fire chamber, is a deflector shield which reflects heat back into the combustion chamber. This ensures that as much heat as possible is retained in the stove and emitted into the room in a controlled manner.
What are TEMA standards?
TEMA stands for “Tubular Exchangers Manufacturers Association” and is a set of standards that were developed by leading shell and tube manufacturers. These standards define the style of heat exchanger and the machining and assembly tolerances. … TEMA C is the least restrictive and most widely used.
