Product Details
Product Description
The economizer is the core energy-saving auxiliary equipment of the boiler, which improves the thermal efficiency of the boiler by 5% -10% by recovering the waste heat of flue gas to preheat the feedwater. Made of 304 stainless steel/cast iron material and equipped with finned tube wear-resistant structure, it can withstand high temperatures of 300-600 ℃ and high pressures of 1.6-4.0MPa. It is suitable for various types of boilers such as coal-fired, gas-fired, and biomass boilers and supports customization. It is the preferred equipment for industrial cost reduction and efficiency improvement.

Company Profile
Packing & Delivery
Our economizers are packaged in sturdy wooden cases for safe handling and long-distance transportation, or directly loaded into standard containers, ensuring intact delivery and compliance with international shipping requirements for industrial equipment.
FAQ
Q1:What are the key materials of your economizer, and can they withstand high-temperature and high-pressure working conditions? A1:Our economizers are mainly made of high-quality carbon steel or alloy steel. The materials comply with international standards such as ASTM and DIN, and can stably operate under the temperature of 400℃ and pressure of 10MPa, fully meeting the working requirements of industrial boilers. Q2:requirements of industrial boilers. A2:We adopt two professional packaging schemes: heavy-duty wooden cases with anti-collision buffer materials for small batches, and standard container loading with fixed brackets for large orders. All packages are waterproof and rust-proof, and pass the international shipping drop test to avoid damage during transit. Q3:Can you customize the economizer according to our boiler’s specific parameters and site conditions? A3:Yes, we provide OEM/ODM customization services. Just provide your boiler’s model, rated capacity, flue gas temperature, and installation space dimensions. Our R&D team will design the matching structure, tube arrangement and connection mode to ensure perfect adaptation. Q4：What is the warranty period of your economizer, and how to solve the after-sales problems in overseas markets? A4：The warranty period of our economizers is 12 months from the date of commissioning. We have established cooperative after-sales service stations in major regions worldwide. For faults, we can provide online technical guidance within 24 hours, and send professional technicians to the site if necessary. Q5：How does your economizer improve the boiler’s thermal efficiency, and what is the specific energy-saving effect? A5：Our economizer preheats the boiler feedwater by recovering the waste heat of flue gas, which can reduce the exhaust gas temperature by 100–150℃. It is verified that the thermal efficiency of the boiler can be increased by 5%–8% after installation, significantly reducing the fuel consumption and operation cost.
