H economizer, H evaporator, H superheater, H air heater and etc.
Product Introduction
Boiler economizers are heat exchange devices with finned tubes that heat liquids, typically water, up to but not exceeding the boiling point. We manufacture three types of boiler economizers: bare tube economizer, H finned tube economizer, and spiral finned tube economizer.
The H-finned tube economizer is a high-efficiency heat exchanger consisting of H-finned tubes. Compared with bare tube economizers, H-finned tube economizers significantly enlarge the heat exchange area while reducing the number of tubes required. This design also increases flue gas flow area to reduce flow speed and minimize abrasion.
H-finned tubes can be manufactured as double H finned tubes with high rigidity to accommodate long tube rows. The spiral finned economizer represents newly designed heat transfer equipment that utilizes spiral fin tubes to overcome serious abrasion issues and extend service life.
Function and Benefits
The economizer functions to "economize" or save on cooling costs by enabling compressor shutdown while maintaining adequate cooling capacity, resulting in significant energy savings and reduced operational expenses.
Zhangjiagang Hua Dong Boiler Co., Ltd., founded in 1985, specializes in manufacturing power station boilers, industrial boilers, HRSGs, waste incineration boilers, biomass boilers, and related heating surface components. We provide integrated services from design and manufacturing to installation and maintenance.
