A shell-and-tube heat exchanger is a common type of heat exchanger used in various industrial applications, including heat recovery boilers. This type of heat exchanger consists of a cylindrical shell (pressure vessel) with a bundle of tubes inside. The shell contains one fluid, and the tubes typically contain another fluid. In the context of a heat recovery boiler, the fluids involved are often flue gas on one side and water or steam on the other.

In a heat recovery boiler, the shell-and-tube heat exchanger plays a critical role in capturing and utilizing waste heat from the combustion process, contributing to improved energy efficiency in industrial operations.
