It can be understood that when the coal amount of the coal in the real-time coal stacking information is 0, the current operation of setting the blending proportion of the coal types may not be performed smoothly, and by limiting the circulation process in this case, the actual coal blending and burning process can be performed more effectively.
On the basis of the above embodiment, the technical solution is further described and optimized in this embodiment, and specifically, after determining, according to each target combustion state data in the circulation process, an actual coal blending proportion corresponding to each stage in the blending combustion process of the coal, when the circulation condition meets the preset condition, this embodiment further includes:
