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

Design of Finned Tube Economizer1. Design ObjectivesImprove heat exchange efficiency: Enhance heat exchange capacity by increasing surface area and optimising fluid flow.Reduce energy consumption: Reduce the consumption of coal and lower the operation cost.Durability: Ensure the long-term stability

Thermal Expansion Structure Economizer for Petrochemical Industry

Coal economiser for 2 tonne biomass steam boilerBiomass Steam Boiler (Biomass Steam Boiler) is a type of boiler equipment that uses biomass fuels (e.g. wood chips, straw, rice husk, etc.) to generate steam. Coal economiser (Economizer) is an important component in the steam boiler system, which is u

How a Boiler Economiser Works?A boiler economiser (Boiler Economizer) is a device used to increase the heat utilisation of a boiler. It is usually installed on the flue gas discharge pipe of the boiler, and is used to recover the waste heat in the flue gas and transfer it to the boiler feed water or
