Vapour Economizer for Boiler Waste Heat Recovery
The waste heat recovery unit (WHRU) revolutionizes industrial boiler efficiency by capturing exhaust heat that would otherwise be lost. Featuring stainless steel (SS) economizer tubes with enhanced fin designs, it extracts thermal energy from flue gases, preheating feedwater before it enters the boiler. This reduces fuel consumption by up to 20% and cuts CO₂ emissions. During production, the SS economizer heat exchanger undergoes precision welding and stress-relief treatment to ensure durability in high-temperature, corrosive environments. With a heat transfer coefficient of 800 W/m²K, it efficiently recovers heat from exhaust gases up to 400°C. Ideal for power plants and manufacturing facilities, it integrates seamlessly with existing boiler systems, providing a rapid return on investment through reduced energy costs.

Design & Functionality
◆ Waste Heat Recovery Innovation
Captures exhaust heat (otherwise wasted) to preheat feedwater before it enters the boiler. The enhanced fin design increases surface area, boosting heat extraction from flue gases-critical for district heating hot water production.
◆ Durability in Harsh Environments
SS 316L tubes undergo precision welding and stress - relief treatment, ensuring 15+ years of operation in high - temp, corrosive conditions (e.g., coal - fired power plant flue gases).
Application Areas
◆ District Heating Systems
Converts exhaust vapour to hot water for residential/commercial heating, reducing reliance on fossil fuels for thermal energy.
◆ Industrial Boilers
Power Plants (Coal/Gas/Biomass): Improves boiler efficiency by 3–5%, cutting CO₂ emissions and fuel costs.
Manufacturing Facilities: Reduces energy use in steam - dependent processes (e.g., textiles, food processing).
