The design solutions of these heat exchangers are discussed.Share:

An S-type floating head should be used when thermal expansion needs to be allowed for and access to both sides of the exchanger is required from cleaning. Other rear head types would not normally be considered except for the special cases.

The MBBR wastewater treatment process is quite flexible. It is used for domestic and industrial wastewater treatment and can be designed for BOD removal alone or in combination with nitrification or with nitrification and denitrification. It is used as a single stage process or as a two-stage or three-stage process.

Ground heat exchanger design for direct geothermal energy systems.

The marine industry relies heavily on plate and frame heat exchangers, as PHEs help maintain the primary engine oil cooler and the freshwater cooler. These exchangers serve other purposes on ships, too, as they help with tap-water production systems and HVAC systems. The main reasons PHEs are chosen over shell-and-tube exchangers is that they are much more efficient and compact, making them more suitable for the marine industry.

Coil spacing and tube diameter had a lesser impact upon system performance than heat exchanger shell length and number of helices.

The design of earth–air heat exchanger mainly depends on the ..

A second area of the food and beverage industry in which these specific exchangers operate is brewing, where they are used for wort boiling and cooling, as well as beer cooling. The third area they are used is in the production of soft drinks. The exchangers serve the purposes of water heating, energy drink pasteurization, sugar dissolving, and syrup pasteurization. And finally, within this industry, plate and frame heat exchangers play a part in fruit and juice processing.

Heat exchanger designs were subject to variations in system parameters, such as collector area, hot water draw, location and glycol flow rate.

Strictly speaking this is not a TEMA designated type but is generally recognized. It can be used as a front or rear header and is used when the exchanger is to be used in a pipe line. It is cheaper than other types of headers as it reduces piping costs. It is mainly used with single tube pass units although with suitable partitioning any odd number of passes can be allowed.

This is the cheapest of all removable bundle designs, but is generally slightly more expensive than a fixed tubesheet design at low pressures.

Plate and frame heat exchangers serve many different purposes and are used in multiple industries. Within the food and beverage industry, the exchangers play a role in dairy production, as they are used in milk and cream pasteurization, milk reception, and ultra-high temperature sterilization (UHT). In regards to pasteurization, it is a process that involves heating certain food items to a specific temperature for a set period of time. The goal of this process is to kill microorganisms that could foster disease, spoil food, or lead to undesired fermentation. PHEs not only play a role in milk and cream pasteurization, but they also help purify many other products, too.

It was found that considerably reducing the heat exchanger size led to enhanced economic performance over a 10 year period of economic analysis.

and is shown to be a useful tool for heat exchanger design.

The mechanical design of a shell and tube heat exchanger provides information on items such as shell thickness, flange thickness, etc. These are calculated using a pressure vessel design code such as the Boiler and Pressure Vessel code from ASME (American Society of Mechanical Engineers) and the British Master Pressure Vessel Standard, BS 5500. ASME is the most commonly used code for heat exchangers and is in 11 sections. Section VIII (Confined Pressure Vessels) of the code is the most applicable to heat exchangers but Sections II—Materials and Section V—Non Destructive Testing are also relevant.
