The basic thermal design theory for recuperators is presented in Chapter 3, advanced design theory for recuperators in Chapter 4, and thermal design theory for regenerators in Chapter 5. Pressure drop analysis is presented in Chapter 6.
Geankoplis 4th ed. 4.5‐4. Water flowing at a rate of 13.85 kg/s is to be heated from 54.5 to 87.8oC in a double‐pipe heat exchanger by 54,430 kg/h of hot gas flowing counterflow and entering at 427oC ( 1.005 / ).
Abstract. This chapter provides an overview of how different heat exchanger types, prob-lems, and networks are analyzed. Heat exchangers are categorized by shape, flow arrangement, area to volume ratio, and channel size. The problem type depends on what information is available and what is sought.
The heat exchanger must withstand the service conditions of the plant environment. The exchanger must be maintainable. In other words, a configuration that permits cleaning and replacement of any component that is especially vulnerable to corrosion, erosion, vibration, or aging, must be chosen.

Heat Exchangers DOE-HDBK-1018/1-93 TYPES OF HEAT EXCHANGERS. Plate. Figure 1 Tube and Shell Heat Exchanger. A plate type heat exchanger, as illustrated in Figure 2, consists of plates instead of tubes to separate the hot and cold fluids. The hot and cold fluids alternate between each of the plates. Baffles direct the flow of fluid between plates.
Heat transfer theory The natural laws of physics always allow the driving energy in a system to flow until equilibrium is reached. Heat leaves the warmer body or the hottest fluid, as long as there is a temperature difference, and will be transferred to the cold medium. A heat exchanger follows this principle in its endeavour to reach equalisation.
