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.
A heat exchanger follows this principle in its endeavour to reach equalisation. With a plate type heat exchanger, the heat penetrates the surface, which separates the hot medium from the cold one very easily. It is therefore possible to heat or cool fluids or gases which have minimal energy levels. The theory of heat transfer from one
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.
To introduce and apply basic heat exchanger design concepts to the solution of industrial heat exchanger problems. Primary emphasis is placed on fundamental concepts and applications. Also, more emphasis is placed on analysis and less on empiricism.
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.
