Product Introduction
Boiler economizers are heat exchange devices with finned tubes that heat liquids, typically water, up to temperatures that do not exceed the boiling point. We manufacture three types of boiler economizers: bare tube economizers, H finned tube economizers, and spiral finned tube economizers. The H-finned tube economizer is a highly efficient heat exchanger consisting of H-finned tubes.
Compared with bare tube economizers, H-finned tube economizers significantly increase the heat exchange surface area while reducing the number of tubes required. This design also expands the flue gas flow area, reducing flow velocity and minimizing abrasion.
H-finned tubes can be manufactured as double H finned tubes, providing high rigidity suitable for long tube rows. The spiral finned economizer is a newly designed heat transfer equipment that utilizes spiral fin tubes to overcome serious abrasion issues and extend service life.
Function
The primary function of the economizer is to "economize" or reduce cooling costs. By enabling compressor shutdown while maintaining adequate cooling capacity, significant energy savings can be achieved.
