Heat Exchanger Design Handbook T. 5 Heat Exchangers The general function of a heat exchanger is to transfer heat from one fluid to another. The software is user friendly and can be used to make preliminary sizing calculations that will help to give a clear outlook of the initial. Heat Exchanger Rating based on Bell Delaware method. Or use interheaters between adiabatic reaction stages. your number one source for high quality heat exchanger products. In order to control microfouling, power plants. Organic Rankine Cycle (ORC) systems are used for power production from low to medium temperature heat sources in the range of 80 to 350 °C and for small-medium applications at any temperature level. Typical Shell-and-Tube Heat Exchanger Shell-and-tube heat exchangers are described based on the number of passes the shell-side and tube-side fluids must undergo. in the inner tube.
