摘要
对不同配比下由烟煤、无烟煤和褐煤掺混得到的混煤的燃烧性能进行了热天平试验研究 ,对不同配比下混煤的活化能进行了计算 ,并根据活化能与着火温度随掺混比的变化规律对混煤的着火特性进行了探讨 ;此外根据不同掺混比下煤样的试验数据 ,从阿累尼乌斯定律出发 ,提出了表征煤在着火后燃烧速度和燃烧稳定性指数 HF,对不同配比下煤的 HF 进行了计算 ,并据此对混煤的稳燃及燃尽性能进行了研究。图 1 1表2参
A combustion experiment on blended coals composed by two coals of a bituminous, a anthraciteand and a lignite is carried out using a thermal balance. The active energies of blended coals are calculated. Furthermore, a combustion index of H F is presented. The H F of blended coals with different blending ratio is calculated. According to the experiment and calculated results, the combustion performance of blended coals under different blending ratios is discussed. Figs 11, tables 2 and refs 5.
