本文通过利用石煤渣作床料,在冷态试验台上进行的试验,对固体颗粒特性、固定床阻力、临界流化速度和流化特性进行了研究,得出了准则关系式和实用展开式.这些结果可供燃用石煤沸腾炉的设计和运行作参考. In this paper, the use of stone coal cinder as a bed, the cold test bench on the test of solid particle characteristics, fixed bed resistance, the critical fluidization velocity and fluidization characteristics were studied, and the relationship between the standard and practical expansion These results are useful as a reference for the design and operation of coal-fired boilers.
