AI Technical Summary

Technical Problem

The existing multi-purpose burners have a fixed combustion chamber length, which cannot take into account the combustion characteristics of pulverized coal and natural gas. This results in insufficient flame residence time and an increase in unburned particles during pulverized coal combustion, and a decrease in thermal efficiency during natural gas combustion.

Method used

The first and second combustion chambers, which adopt a sleeve-type telescopic structure, adjust the length of the combustion chamber by a drive motor, and adjust the blade angle during fuel switching in conjunction with the air direction adjustment component to form a strong vortex, ensuring complete combustion of pulverized coal and reducing heat loss.

Benefits of technology

It enables stable switching of the burner between different fuels, improves combustion efficiency and stability, and ensures complete combustion of pulverized coal and improved thermal efficiency of natural gas.
