先导式逆向直流给料超浓相自维持二次施流各类煤种稳燃系统
By using a pilot-operated reverse DC feeding ultra-dense phase self-sustaining secondary flow system, the problem of unstable combustion flame under low load operation of coal-fired boilers is solved by utilizing the rotation of the main rod and the movement of the conveyor rod, thus achieving uniform fuel injection and stable combustion.

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