针对1 MWth循环流化床锅炉试验台设计,采用计算流体力学软件FLUENT6.3,对炉膛内部煤颗粒和油页岩颗粒流动分别进行数值模拟。结果表明:烟煤和油页岩颗粒在循环流化床内流动均符合“环-核”流动;颗粒对左边的冲击大于右边,在实际运行中应着重对炉膛左侧采取防磨措施;稀相区油页岩颗粒压力衰减速度快于烟煤颗粒。 Aiming at the design of a 1 MWth circulating fluidized bed boiler test bench, the computational fluid dynamics software FLUENT6.3 was used to simulate the flow of coal particles and oil shale particles inside the furnace respectively. The results show that the bituminous coal and oil shale particles flow in the circulating fluidized bed are in line with the “ring - core” flow; the impact of the particles on the left is greater than the right, and in the actual operation should focus on the left side of the furnace to take anti - The dilute phase oil shale particle pressure decay faster than the bituminous coal particles.
