研究火焰炉热工的中心课题是弄清三类变量之间的相互关系:①结构参数,操作参数;②热工过程参数;③生产指标.其中尤其重要的是要弄清①③两类变量之间的关系.这是因为人们所能直接规定或操纵的因素,既不是热工过程参数(如黑度、温度等),更不是生产指标,而是结构和操作参数(如受热面积、热负荷、空气用量等).合理选取这些参数是提高炉子生产率、热效率,延长炉子使用寿命的重要手段.
The central task of the study of flame furnace thermal engineering is to clarify the relationship between the three types of variables: ① structural parameters, operating parameters; ② thermal process parameters; ③ production indicators. Of particular importance is to understand ① ③ two types of variables This is because the factors that people can directly regulate or manipulate are neither thermal process parameters (such as blackness, temperature, etc.), nor production indexes, but structural and operating parameters (such as the heating area, thermal load , The amount of air, etc.) Reasonable selection of these parameters is to improve the furnace productivity, thermal efficiency, an important means to extend the service life of the stove.
