1. Recovers Waste Heat from Flue GasesBoilers generate high-temperature flue gases (typically 300–500°C) as a byproduct of fuel combustion. Without an economizer, these gases would exit the chimney, losing significant heat to the atmosphere.The economizer intercepts these flue gases and transfers th

Economizer for Steam BoilerAn economizer for a steam boiler is a crucial auxiliary component designed to enhance the boiler's thermal efficiency by preheating the feedwater using the heat from the boiler's exhaust gases.

Performance IndicatorsBare Tube BundleFinned Tube BundleHeat Transfer EfficiencyLower. Relying only on the smooth surface of the tube itself, the heat transfer area per unit volume is small (usually 10-30 m²/m³) and the heat transfer coefficient is low (about 30-60 W/(m²・K) on the flue gas side).Hig
