摘要
对不同固气比下煤粉的燃烧特性进行了数值模拟和理论分析。结果表明：（１） 随着固气比的增加，风口内煤粉燃烧率增加；（２） 固气比为２０ｋｇ（ 煤粉）／ｋｇ（ 气）时，风口端部平均温度最低；（３） 为提高高炉煤比，固气比应达到３０ｋｇ（ 煤粉）／ｋｇ（ 气） 以上。
Synopsis The combustion characterization of pulverized coal with various solid-gas ratios have been analyzed by mathematical models and theory research. Results can be summarized as follows:1) with increasing of solid-gas ratio pulverized coal burnout ratio in tuyere increases; 2)Average temperature at tuyere tip is the lowest when solid-gas ratio is 20kg/kg; 3)To increase pulverized coal ratio of BF solid/gas ratio must be larger than 30kg/kg.
