The A-type front header is the standard for dirty tubeside fluids and the B-type is the standard for clean tubeside fluids. Shell and Tube Heat Exchangers are one of the most popular types of exchanger due to the flexibility the designer has to allow for a wide range of pressures and temperatures. Also, U-tube designs are limited to even numbers of tube passes. Calculate tubeside pressure drop see, for example, Pressure Drop, Single Phase. However, since internal cleaning of the tubes by mechanical means is difficult, it is normal only to use this type where the tube side fluids are clean. See also Augmentation of Heat Transfer. Front Header—this is where the fluid enters the tubeside of the exchanger.
