[0002] In the combustion process of the boiler, accurate and timely fuel delivery is crucial to maintaining combustion efficiency and safe operation of the boiler. However, the existing fuel delivery equipment has exposed some obvious shortcomings in practical applications.

[0003] First, the feed amount of these devices is often set to a fixed value, and cannot be flexibly adjusted according to the actual combustion conditions of the boiler or the quality of the fuel. This inflexible feeding method may not only lead to fuel waste, but also affect the combustion efficiency of the boiler due to insufficient feeding, and even cause safety hazards.
