High Efficiency Boiler Economizer with Max. 20t/h Steam Production and 5 Years Core Components Warranty

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 highly efficient heat exchanger consisting of H-finned tubes. Compared to bare tube economizers, H-finned models offer:

• Larger heat exchange area
• Reduced number of tubes required
• Increased flue gas flow area
• Lower flue gas flow speed and reduced abrasion

Our double H-finned tubes feature high rigidity for long tube row applications. The spiral finned economizer is our newest design, specifically engineered to overcome abrasion issues and extend service life.

The economizer's primary function is to reduce cooling costs by allowing compressor shutdown while maintaining adequate cooling capacity, resulting in significant energy savings.

Founded in 1985, Zhangjiagang Hua Dong Boiler Co., Ltd. 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.

38 years of industry experience in research, development and manufacturing with substantial production capacity.
