摘　　要：为了考察气化炉炉侧喷嘴入口位置对炉内流场和颗粒浓度分布的影响规律,在新型水煤浆气化炉冷模三维实验台上进行了大量的实验研究,并与数值模拟计算结果进行了对比,结果表明,当喷嘴距气化炉顶部0.9m时,气化炉炉内流场分布最合理,颗粒浓度分布最均匀;实验测试结果和数值模拟计算结果非常接近,进一步验证了数值模拟计算结果的准确性.实验测试结果为气化炉的设计和运行提供了参考.In order to examine the effect of different height of furnace side nozzle upon the distribution of flow field, particle concentration, the 3-D flow field in a new type CWS gasifier at cold state was analyzed using experimentation method, and contrasted this results with numerical simulation results. The optimization distribution was observed with the height 0.9 m far from the furnace top. Experimentation study results and numerical simulation results is very near, attest to the numerical simulation is exact, which can be seen as a gui-dance for designing and operating of this type gasifier.
