Selection and costing of heat exchangers.
Abstract:ESDU 92013 gives guidance on the selection of heat exchanger types for a given duty against various criteria; they include the general characteristics, together with such detailed aspects as the ranges of pressure and temperature appropriate, compatibility of the fluids involved, space and weight requirements, and cleaning accessibility and maintenance. That allows an initial choice to be made from 18 principal types of exchangers. The various types are all illustrated. A final choice can then be made between the feasible types on the basis of costs. Detailed costing data provided by manufacturers are tabulated as a function of heat load, operating pressure and the types of single-phase and boiling/condensing cold- and hot-side fluids for the following types of exchangers: shell-and-tube, double-pipe, printed circuit, plate- fin, air-cooled and welded plate. Costing data are also tabulated as a function of heat load and the types of cold- and hot-side fluids for gasketed-plate exchangers. Seven worked examples of selection based on technical suitability and using the tabulated cost data illustrate fully the use of the information.
- Air-Cooled Heat Exchangers
- Crossflow Heat Exchangers
- Double-Pipe Heat Exchangers
