着重研究了在高入口颗粒浓度下方形分离器的分离机理。试验证实：在入口颗粒浓度较高时，颗粒的分离机理远远不同于低入口颗粒浓度下的分离机理。在入口颗粒浓度较高时，有即时分离现象存在，这在旋风分离器的试验中也曾得到证实。这种现象与气流所能携带的饱和夹带量有关，超过气流饱和夹带的部分在分离器进口处即被分离。在大量试验数据分析的基础上，给出了相应的新的极限负荷计算公式和分离效率计算公式。实践证明：即时分离理论可用于指导循环流化床锅炉方形分离器的设计和研究工作。图５表２参７。
The separation mechanism of the square separator at high entrance particle concentration is emphatically studied. Experiments show that at higher inlet particle concentrations, the separation mechanism of the particles is far different from the separation mechanism at low inlet particle concentrations. In the inlet particle concentration is higher, there is an immediate separation phenomenon, which has been confirmed in the cyclone test. This phenomenon is related to the amount of saturated entrainment that can be carried by the gas stream, and the portion that is saturated with the gas flow is separated at the separator inlet. Based on a large number of experimental data analysis, the corresponding new formula for calculating the ultimate load and the separation efficiency are given. Practice has proved that the real-time separation theory can be used to guide the design and research work of a square separator for a circulating fluidized bed boiler. Figure 5 Table 2 Reference 7.
