Exhaust Heat Exchanger with Vapour Economizer for Boilers

The heat recovery system operates at pressures up to 10 MPa, handling high-volume steam flows while minimizing pressure drop. Constructed with corrosion-resistant SS tubes, it withstands aggressive condensate and acidic environments. During operation, the economizer recovery unit preheats feedwater by 50-80°C, reducing boiler fuel requirements and extending equipment lifespan. Used in coal-fired, gas, and biomass power plants, it improves overall plant efficiency by 3-5%, aligning with sustainability goals.Engineered for power generation applications, this advanced economiser heat exchanger maximizes thermal efficiency in steam cycles.
Product Details
Basic Information
◆ Place of Origin: China
◆ Brand Name: [Customizable, e.g., EcoTherm]

Product Overview
◆ This exhaust heat exchanger, integrated with a vapour economizer for boilers, recovers heat from 400°C flue gases to preheat combustion air. Designed for refinery furnaces and power plants (coal - fired, gas, biomass), it optimizes energy use, reduces fuel consumption, and enhances overall plant efficiency.
Key Specifications
◆ Construction Materials
Tubes: Corrosion - resistant stainless steel (SS 310S/316L). Withstands aggressive condensates and acidic environments from flue gases.
Shell: High - strength carbon steel (optional: alloy steel for extreme temps). Ensures structural integrity under high - pressure operations.
◆ Performance Parameters
Pressure & Flow: Operates at pressures up to 10 MPa, handling high - volume steam flows with minimal pressure drop.
Heat Recovery & Efficiency: Preheats feedwater by 50–80°C, improving plant efficiency by 3–5%. Reduces boiler fuel requirements, extending equipment lifespan.
Design & Functionality
◆ Vapour Economizer Integration
The exchanger recovers waste heat from 400°C flue gases, using it to preheat combustion air/feedwater. This reduces the boiler's fuel demand, cutting energy costs and carbon emissions.
◆ Corrosion Resistance & Durability
Stainless - steel tubes resist corrosion from acidic flue gas condensates, ensuring long - term operation in harsh refinery and power plant environments. The robust design minimizes maintenance and extends service life to 15+ years.
