H Type Fin Tube Boiler Economizer with Max. 20t/h Steam Production 1 Year Warranty and 5 Years Core Components Warranty
High-efficiency boiler economizer designed as ship spare parts exhaust gas economizer, manufactured to ASME standards for power plant applications.
Boiler economizers are heat exchange devices with finned tubes that heat liquids (typically water) without exceeding the liquid's boiling point. We manufacture three types of boiler economizers:
- Bare tube economizer
- H finned tube economizer
- Spiral finned tube economizer
The H-finned tube economizer is a high-efficiency heat exchanger consisting of H-finned tubes. Compared to bare tube economizers, H-finned tube economizers offer:
- Larger heat exchange area with fewer tubes
- Increased flue gas flow area to reduce flow speed and abrasion
- Option for double H finned tubes with high rigidity for long tube rows
The spiral finned economizer features newly designed heat transfer equipment with spiral fin tubes to overcome abrasion issues and extend service life.
The economizer reduces cooling costs by allowing compressor shutdown while maintaining adequate cooling, resulting in significant energy savings.
