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. Primary Functions of an EconomizerHeat Recovery: Extracts waste heat from flue

Design Considerations of Bare Tube Low Pressure Boiler EconomizerPressure and Temperature ConstraintsLower Pressure: Operates with feedwater pressures typically <2.5 MPa (vs. high-pressure economizers at 10–15 MPa), matching the low-pressure feedwater circuit (e.g., preheating condensate or deaerato

Advantages of Bare Tube Low Pressure Boiler EconomizerHeat Transfer PerformanceModerate Efficiency: Bare tubes have lower heat transfer coefficients (typically 30–60 W/(m²·K) for flue gas-side) compared to finned tubes (80–150 W/(m²·K)), but this is acceptable in low-temperature, low-heat-flux zones
