Heat Recovery Steam Generator

The Heart of Combined-Cycle Power Generation

Heat Recovery Steam Generators (HRSG) are critical components in modern combined-cycle power plants, capturing waste heat from gas turbine exhaust to generate steam that drives additional turbines — significantly boosting overall plant thermal efficiency.

At MEEM, we manufacture the complete range of HRSG components and assemblies, from individual finned tubes and headers to fully integrated shop-assembled modules. Our products serve both new construction projects and retrofit/replacement applications globally.

Component Details

HRSG Product Portfolio

From individual finned tubes to fully integrated shop-assembled modules — every component is engineered, fabricated, and tested to the most demanding international standards.

01

Finned Tubes

High-performance finned tube assemblies are the foundational heat transfer elements in any HRSG. MEEM manufactures precision finned tubes using advanced high-frequency resistance welding (HFRW) and laser welding technologies.

Fin Types Solid · Serrated · H-type · I-type

Materials CS · LA · SS · Ni-alloys

Applications Econ · Evap · SH · RH · Preheater

Headers & Manifolds

Custom-engineered headers form the pressure boundary distribution system within each HRSG module section. Fabricated from small-bore collector manifolds to large-diameter steam drum-quality header assemblies.
