AI Technical Summary

Technical Problem

Existing coal-fired boilers have unstable combustion flames under low load operation, especially during the rotation and release of fuel, which can easily lead to flame deviation on one side. The lack of an effective supplementary mechanism results in uneven combustion.

Method used

The system employs a pilot-operated reverse DC feeding system for ultra-dense phase self-sustaining secondary flow. Through the rotation of the main rod and the movement of the conveyor rod, the fuel is deployed and ejected at a specific location. Combined with oxygen replenishment, this ensures stable combustion of the fuel.

Benefits of technology

It achieves uniform fuel injection during the rotating combustion process, enhances combustion stability, avoids flame deviation, and improves combustion efficiency and complete fuel combustion.
