本文介绍了几种用于循环流化床的飞灰分离装置，包括内隔板式百叶窗分离器、下排气旋风分离器的冷态试验结果，并给出了内隔板式百叶窗分离器及下排气旋风分离器的优化设计参数。结果表明，根据不同情况采用不同分离器的优化组合可改善和提高现有流化床锅炉飞灰分离装置的水平。图１０参６ In this paper, several kinds of fly ash separation devices for circulating fluidized bed are introduced, including the results of cold test of the inner louver separator and the lower exhaust cyclone, and the inner louver separator and Under the exhaust cyclone optimization design parameters. The results show that the optimal combination of different separators can improve and enhance the level of the existing fly ash separator in a fluidized bed boiler. Figure 10 reference 6
