Product Introduction
Boiler economizers are advanced heat exchange devices featuring finned tubes that efficiently heat liquids while maintaining temperatures below boiling points. We specialize in manufacturing three distinct economizer types: bare tube economizers, H finned tube economizers, and spiral finned tube economizers.
The H-finned tube economizer represents a high-efficiency heat exchange solution constructed from specialized H-finned tubes. Compared to traditional bare tube economizers, this design significantly expands the heat exchange surface area while reducing the total number of tubes required. This configuration also increases flue gas flow area, effectively reducing flow velocity and minimizing abrasion.
H-finned tubes can be manufactured as double H finned tubes, providing enhanced rigidity suitable for extended tube row applications. The spiral finned economizer incorporates a newly engineered design utilizing spiral fin tubes to address issues of severe abrasion and extend service life.
System Functionality
The primary function of the economizer is to optimize energy efficiency and reduce operational costs. By enabling compressor shutdown while maintaining adequate cooling capacity, significant energy savings are achieved.
