AI Technical Summary

Technical Problem

Existing flat flame burners have high head temperatures, short service life, and inefficient heat utilization, resulting in energy waste.

Method used

A cooling groove is installed inside the front panel of the flat flame burner to cool the combustion gas at a lower temperature. The design of the inner and outer nozzles forms a swirling flow to improve the combustion effect and heat utilization rate.

Benefits of technology

It improves the service life of the burner, reduces energy consumption, enhances the combustion effect, and enables the secondary utilization of heat.
