AI Technical Summary

Technical Problem

When adjusting the secondary air intake of existing swirl burners, the air volume at the front of the air intake pipe is relatively large, which can easily damage the blades. Furthermore, it is impossible to adjust the air volume at the front of the pipe and the blade opening degree simultaneously, which can lead to damage to the device.

Method used

Design a secondary airflow pulsation control device for a gas turbine swirl burner. Through the regulating cylinder between the exhaust pipe and the intake pipe, the air guide assembly, and the synchronous regulating assembly, the air volume and opening degree are matched and regulated to protect the blades and optimize the combustion effect.

Benefits of technology

It achieves synchronous adjustment of air volume and opening degree, protects the blades, improves the stability and combustion efficiency of the burner, and reduces NOx generation.
