Inlet/Outlet Manifolds

Inlet/Outlet Manifolds are engineered piping assemblies in gas coolers designed to evenly distribute incoming hot gas to the heat exchanger tubes (inlet manifold) and collect cooled gas from the tubes (outlet manifold). They ensure uniform flow distribution, minimize pressure drop, and optimize thermal performance by preventing channeling or dead zones. Typically fabricated from corrosion-resistant metals, these manifolds feature precise internal geometries, such as tapered sections or flow dividers, to manage gas velocity and turbulence. They connect to the gas cooler's tube bundle via headers and include flanges or welded joints for system integration, with designs varying based on operating pressure, temperature, and gas composition.

The working principle involves directing gas flow through the manifolds to achieve uniform distribution across the heat exchanger surface. The inlet manifold receives high-temperature gas from the process and channels it into multiple parallel tubes, while the outlet manifold collects the cooled gas from these tubes and directs it out of the system. This design maximizes heat transfer efficiency by ensuring consistent gas contact with cooling surfaces, reducing thermal stress, and maintaining system pressure within specified limits.
