Steam Shell and Tube Heat Exchanger

Definition and Basic Concept

The Steam Shell and Tube Heat Exchanger is a widely used industrial heat transfer device designed to exchange heat between two or more fluids without mixing them. The equipment consists of an outer shell and a bundle of tubes. One fluid (typically steam) flows through the tubes (tube-side fluid), while another fluid (such as water, oil, or other process fluids) flows outside the tubes within the shell (shell-side fluid). Heat transfers from the higher-temperature fluid to the lower-temperature fluid through the tube walls via thermal conduction.

Key Features (Data Presentation)
