Hua Dong Boiler Differential Pressure Boiler Economizer with Max. 20t/h Steam Production and 1 Year Warranty - New Product 2020

Boiler economizers are heat exchange devices with finned tubes that heat a liquid, sometimes water, up to however sometimes doesn't exceed the boiling purpose of liquid.

We manufacture three types of boiler economizers:

• Bare tube economizer
• H finned tube economizer
• Spiral finned tube economizer

H-finned tube economizer is a high efficient heat exchanger consisting of H-finned tubes. Compared with bare tube economizer, H-finned tube economizer can:

• Enlarge the heat exchange area
• Reduce the number of tubes
• Increase flue gas flow area
• Reduce flue gas flow speed and abrasion

H-finned tubes can be made as double H finned tubes, with high rigidness to fit long tube rows. The spiral finned economizer is a newly designed heat transfer equipment that consists of spiral fin tubes to overcome serious abrasion and short service time.

The function of the economizer is to "economize" or save on cooling costs by allowing the compressor to be shut down while still providing adequate cooling, resulting in energy savings.

• Impact test and Strength calculation report with applied materials information
• 100%NDT(non-destructive inspection) report of steel plate, tube and electrode
• X-ray, γ-ray and liquid penetrant test inspection report (welding seam) to ensure the quality of the entire boiler
• Hydraulic test report to ensure the standard working pressure and safety
