中文摘要:
      骨类垃圾为厨余垃圾中的重要组成部分,为了缓解厨余垃圾的处理压力,本文选取无烟煤与烟煤分别按照不同比例与牛骨掺混,采用ZTC-B型综合(同步)热分析仪对其混合燃烧过程进行了热重分析,并对结果进行了动力学分析。结果表明:煤与牛骨单独燃烧的TG-DTG曲线差异明显;掺混燃烧时随着混合物中牛骨质量分数的增加,DTG峰值温度向着低温区偏移,整体燃烧温度区间变窄,综合燃烧特性指数不断降低,燃尽特性指数不断升高;掺混燃烧过程中会产生协同作用,无烟煤、烟煤与牛骨的混合物在400 ℃左右产生了抑制作用,其相对值分别为-8 %与-4 %,在524 ℃和627 ℃左右产生了促进作用,其相对值分别为7 %和9 %;动力学分析表明采用2个连续一级反应模型可以很好地描述其掺烧过程。
英文摘要:
      Bone waste is an important part of kitchen waste. In order to alleviate the processing pressure of kitchen waste, this paper selects anthracite and bituminous coal mixed with bovine bone according to different proportions, and adopts ZTC-B type integrated (synchronous) thermal analyzer. The thermogravimetric analysis was carried out in the mixed combustion process, and the results were subjected to kinetic analysis. The results show that the TG-DTG curve of coal and bovine bone burning is obviously different. When the mass fraction of bovine bone in the mixture increases, the peak temperature of DTG is toward the low temperature zone. Offset, the overall combustion temperature range is narrowed, the comprehensive combustion characteristic index is continuously reduced, and the burnout characteristic index is continuously increased; synergistic effect occurs in the blending combustion process, and the mixture of anthracite, bituminous coal and bovine bone is inhibited at around 400 ℃. The relative values of the action were -8 % and -4 %, respectively, and the promoting effects were obtained at 524 ℃ and 627 ℃, respectively, and the relative values were 7 % and 9 %, respectively. The kinetic analysis showed that two consecutive first-order reaction models were used. The doping process can be well described.
