Compact Heat Exchangers Improving Heat Recovery-PDF Free Download

The two basic types of heat exchangers are compact and conventional heat exchangers. The ratio of the heat transfer surface area of a heat exchanger to its volume is called the area density β. A heat exchanger with β 700 m2/m3 is classified as a Compact heat exchanger (CHEs) and if β 700 m2/m3 then they are the Conventional heat exchangers.

Spiral heat exchanger for gas turbine systems (courtesy of Rolls-Royce). 2.5 Plate-Fin Heat Exchangers Aluminium plate-fin heat exchangers (PFHE) were initially developed in the 40's to provide compact, light and high efficient heat exchangers for gas/gas applications in the aerospace industry.

Compact heat exchangers can be used in most industrial applications as long as design temperature and pressure are within the accepted range, which normally is up to 450oC and 40 barg. When the applica-tion allows it, compact heat exchangers, either gasketed or fully welded, are often the best alternative in situations when a high-grade, costly

Applications of heat exchangers present two distinct categories of design problems (Sarkomaa 1994): 1. Design and optimization of mass-produced heat exchangers, e.g. automobile radiators, heat exchangers of HVAC equipment, oil cooling heat exchangers for machinery, etc. 2. Design and optimization of

Heat Exchangers Heat exchangers are used to transfer heat between two sources. The exchange can take place between a process stream and a utility stream (cold water, pressurized steam, etc), a process stream and a power source (electric heat), or between two process streams resulting in energy integration and

Heat exchangers are classified according to transfer processes into indirect- and direct-contact types. 1.2.1 Indirect-Contact Heat Exchangers In an indirect-contact heat exchanger, the fluid streams remain separate and the heat transfers continuously through an impervious divid
