HRSG Pressure Part Modules and Coils

Chanute has manufactured HRSG pressure part modules for over thirty years. Our experience covers every size, circulation (forced or natural) and design found in the industry. We support OEMs in the domestic market and supply replacement components to combined cycle operators. Chanute Manufacturing is the only domestic fabricator with on site finned tube production. This allows 100% pressure part fabrication to be performed at one facility providing greater project control and shorter cycle times.

Shop Modular HRSGs

For mid sized com bined cycles the HRSG is manufactured in modular form combining the pressure parts and external casing in one self contained module. Chanute’s casing and assembly capability combined with the heavy lift capacity and rail transportation facilitates large module production.

Pressure Part Coils

For large frame combined cycles the HRSG pressure parts are manufactured as individual coils (or harps). These individual harps are then combined with manifolds, interconnect piping and coil supports to form a complete bundle or module.
