No. 46 – Shell and Tube Heat Exchangers

Steam System Engineering --- Steam Shell and Tube Heat ExchangersThe shell and tube heat exchanger (STHE) is the workhorse in the steam world, and it is used in many process steam applications. The design is very flexible to meet the strenuous requirements found in steam and condensate systems. Because of its flexibility, the STHE can be used to heat different process products, CIP systems, water, process fluids, etc. Simply stated, an STHE has two distinct parts: one is a circular vessel or shell, and the other is the tubes in the shell. Typically, steam is delivered to the shell side and transfers the energy from the steam to the process fluids in the tubes without direct contact or mixing the steam with the fluid.
