Finned tube components
Specify the fin geometry, tube dimensions, materials and connection details.
Heat recovery components
Boiler Economizers
Finned economizer components and tube-bank inquiries built around your project documentation.
Heat-transfer tube details from supplied company materials; confirm the required fin and tube configuration.
Understand the scopeBoiler Economizers
Boiler Economizers
for your project.
Economizers recover heat from flue gas to preheat water. A component inquiry should define the tube and fin arrangement, materials, overall envelope and connection details. Performance figures require a project-specific thermal assessment and are not assumed from a photograph.
A closer look at the components.
Photographs illustrate component arrangements. Confirm the required application and configuration in your inquiry.
Define your requirements
What are you looking for?
Tube-bank assemblies
Provide tube layout, module dimensions and inlet/outlet arrangement.
Replacement scope
Identify the existing component and describe service or maintenance requirements.

Make requirements explicit.
Confirm the inspection requirements for tube and fin connections, materials and dimensional conformity. Performance guarantees require an explicitly agreed design scope.
Documented license scope
GCB’s Chinese Class A boiler component license covers serpentine tubes, headers, membrane walls and finned economizers. Other equipment inquiries require separate confirmation of applicable authorization and supply scope.

Frequently asked questions.
Can you give a heat-recovery figure immediately?
A reliable figure requires operating data and a defined thermal design scope. Send available water-side and gas-side conditions for review.
What should I provide for a replacement economizer?
Existing drawings, tube and fin details, material grades, connection positions and the required quantity.
Can I inquire about a condensing application?
Yes. State the gas composition and temperature conditions, water conditions and corrosion requirements so suitability can be assessed.
