AI Technical Summary

Technical Problem

Traditional boilers do not fully utilize the waste heat from flue gas during operation, resulting in energy waste and environmental pollution from the emission of high-temperature flue gas.

Method used

An auxiliary heating boiler with a steam generator is used. The flue gas used for heating is transported to the spiral heat conduction tube through the gas guide pipe. The waste heat of the flue gas is recovered and transferred to the outer wall of the heating tank. At the same time, the steam generator is used to generate auxiliary steam to increase the total steam volume.

Benefits of technology

It enables the recovery and utilization of waste heat from flue gas, improves heating efficiency, reduces the environmental impact of emission temperature, and reduces heat energy waste.
