本文首先阐述了作者建立的燃烧过程动态分析模型及其初步模拟结果，然后利用此模型模拟研究了煤质变化（如挥发分、碳、灰等）对电站锅炉燃烧稳定性的影响，其主要结论是：在燃烧条件不变的情况下．合碳量不变时，挥发分越高，燃烧稳定性越强；挥发分相近，合碳量稍有增加时，燃烧温度即较明显升高；当挥发分含量增加时，维持燃烧的临界含量碳可降低，此时碳与挥发分含量之和近似不变；同时也显示，同一燃烧条件下对应于可燃极限的临界灰分对不同煤种均应大于同一近似不变之值。
In this paper, the dynamic combustion model and its preliminary simulation results are established. The model is then used to simulate the influence of coal quality changes (such as volatiles, carbon and ash) on the combustion stability of power station boilers. The main conclusions Yes: With the same combustion conditions. When the amount of carbon is constant, the higher the volatility, the higher the combustion stability; the similar to the volatile, the slightly increased carbon content, the combustion temperature is significantly increased; when the volatile content increases, the critical content of the combustion The carbon can be reduced, and the sum of carbon and volatile content is almost the same at the same time. It also shows that the critical ash corresponding to the combustible limit under the same combustion conditions should be greater than the same approximately constant value for different coal types.
