Two-equation turbulence model is used in numerical simulation for the side-air burner, compared with the practical measures and tests, good accordance achives. This method can bring great convenience in analyzing aerodynamical field of boiler. Secondly the method of XRD is used in analyzing the phase transformation in the course of dynamic slagging test, so we can describe the process of slagging comparatively accurately. Last this paper introduces a kind of fuzzy mathematics model which comprises an assemblage combined by seven change factor.

本文首先采用k—ε双方程模型对水煤浆侧边风燃烧器进行了数值模拟，并与实际锅炉燃烧器冷态调试试验结果对比，结果吻合较好，这为我们分析炉内空气动力场特性提供了参考；其次对锅炉结渣动态特性试验，采用XRD的分析方法，较为准确的描述了实际锅炉结渣的过程；最后为了准确的判断出水煤浆的结渣倾向，本文对锅炉结渣的七个影响因素提出了模糊综合判断模型，正确的反映出了该水煤浆的结渣倾向。
