Product Description
High Pressure Flue Gas Boiler Economizer Heat Exchanger
Product Introduction
Boiler economizers are high-efficiency heat exchange devices with finned tubes designed to heat liquids (typically water) without reaching boiling point. We manufacture three specialized types:
- Bare tube economizer
- H-finned tube economizer
- Spiral finned tube economizer
The H-finned tube economizer offers superior heat transfer efficiency with expanded surface area, reducing tube count while increasing flue gas flow area to minimize flow speed and abrasion. Our double H-finned tubes provide exceptional rigidity for extended tube rows. The spiral finned economizer represents our latest innovation, specifically engineered to overcome abrasion challenges and extend service life.
Primary Function
The economizer significantly reduces cooling costs by optimizing heat recovery, allowing compressor shutdowns during adequate cooling conditions while maintaining system performance.
