burner via experiment and simulation, and the reliability of simulation results was verified by experiments. The results show that as the oxygen mole fraction of primary air rises, the combustion...火,燃烧.通过一次风各风道阀门调节火焰形状并适应原料,燃料成分的变化. 图1 分解窑模型示意图 Fig. 1 Schematic diagram of precalciner kiln model 图2 燃烧器结构示意图 Fig. 2 Schematic diagram of burner structure parameters 窑内多相流动......
on the experimental rig, and the model was validated using the obtained experimental results. Dynamic simulation was made based on the model to get a 3-D graph of drum level sloshing, which shows a vivid procedure......
ratio, the small process air velocity is recommended for the burner control to achieve comprehensively better smelting results. Key words: flash smelting; operation parameter; numerical modeling... of computational geometry of CJD burner 闪速炉仿真模型中包含4种边界类型,其中:精矿喷嘴各种反应配风的出口均设置为速度入口边界类型,其速度根据各工况下的实际操作条件确定；模型中烟气出口边界设置在沉淀池东侧测压孔位置,以测压孔压力值为边界条件；由于缺少反应塔与沉淀池的具体冷却条件,反应塔侧壁取壁面挂渣的熔点为温度,底面边界温度取沉淀池渣温,沉淀池气相空间壁面温度取烟......
of the whole method has been verified on a test rig. It is experimentally confirmed that this research provides an important basis for achieving an optimal regulation of spring load distribution... loads. When all those reasons are removed, it is called "the best regulation". The shimming procedure is conducted in a test rig wherein four groups of movable weighing stands with three per group......
: The variation laws of flame temperature field of biodiesel combustion were investigated in a furnace with the swirl burner. The influences of different excess air coefficients and combustion air......
; 文章编号:1672-7207(2014)04-1065-06 Numerical simulation and vibration characteristics of boom system of concrete pump truck test rig REN Wu1, 2, WU Yunxin1, 2, HUA Guangjun1, 2, ZHANG... cylinder has significant influence on the natural frequency too. Finally an experiment is done on a boom test rig to validate the proposed approach above, which provides theoretical basis for the accurate......
-speed motor was coupled to turbocharged system and serves as the load of Brayton cycle, which was used to recover the turbine power. The engine was taken as the burner of Brayton cycle, and its working......
