【摘要】 为探索某水泥分解炉的几何结构对炉内两相流动特性的影响,针对其生料口与三次风口相对位置的几种参数,采用Eulerian模型、phasecoupledSIMPLE方法,数值模拟了炉内气固两相流场,模拟所得的炉内速度矢量、温度分布、压力分布、生料和煤粉的体积分数表明炉内流动趋势合理。经过筛选给出了2个典型方案的模拟结果,进行分析比较后,提出了生料口与三次风口相对位置的一个优化设计方案,为分解炉的进一步研究提供参考。更多还原

【Abstract】 Based on different relative locality between cement raw meal and tertiary air in lets of a big precalciner, the gas-solid two-phase flows of the precalciner we re simulated by Eulerian models and phase coupled SIMPLE method. The results of two typical projects and their velocity, the pressure, temperature and volume fr action were analyzed. An optimal project of relative locality between raw meal a nd tertiary air inlets was put forward, which was highly advantageous to the coa l’s combustion and the decomposition of cement raw meal.更多还原
