The economizer module is a core functional module used in thermal systems such as waste heat boilers and industrial boilers to recover low-temperature flue gas waste heat and preheat boiler feed water. Its main function is to absorb low-temperature heat from the flue gas (usually flue gas temperatures are between 200-400°C) to increase the feed water temperature entering the boiler evaporator, thereby reducing fuel consumption and improving the overall thermal efficiency of the boiler.
By raising the feed water temperature, the economizer module reduces the heat required for fuel combustion, significantly lowering fuel consumption and operating costs, resulting in significant economic benefits. Raising the feed water temperature helps stabilize the boiler's steam pressure and temperature parameters, reducing operational fluctuations. While saving fuel, it also reduces carbon dioxide, nitrogen oxide, and dust emissions. This has positive implications for energy conservation and emission reduction efforts, helping enterprises achieve their "dual carbon" goals. Different economizer designs (smooth tube, pulverized coal, biomass, etc.) can be designed based on boiler type (HRSG, pulverized coal, biomass, etc.) and process requirements. They are adaptable and flexible to varying flue gas temperatures and water quality conditions.

An Economiser In Boiler is a key module in thermal systems, including waste heat boilers and industrial boilers. Its primary function is to recover low-temperature flue gas heat and preheat the boiler feed water. Typically, flue gas temperatures range between 200–400°C. By absorbing this heat, the economizer raises the temperature of the feed water entering the boiler evaporator, which directly reduces fuel consumption and enhances the overall thermal efficiency of the boiler system.
By preheating the feed water, the economizer reduces the amount of energy needed for fuel combustion, resulting in substantial fuel savings and lower operating costs. For industrial facilities, this not only improves profitability but also contributes to more efficient energy use—a key factor in modern industrial operations.
Raising the feed water temperature helps stabilize steam pressure and temperature parameters within the boiler. This reduces fluctuations during operation, ensuring consistent performance and enhancing the reliability of industrial systems, which is a core principle of Wuxi Jinker’s engineering philosophy.
In addition to improving efficiency, Wuxi Jinker’s economizers contribute to environmental sustainability. By reducing fuel consumption, they also lower emissions of carbon dioxide, nitrogen oxides, and particulate matter. These benefits align with global energy conservation goals and support enterprises in achieving their“dual carbon” objectives.
