六回路环形炉膛循环流化床结构布置实验研究
Experimental Study on the Structural Arrangements of a Circulating Fluidized Bed With Annular Furnace and Six Circulating Loops
摘要
Abstract
Cold experiments were conducted on a circulating fluidize bed(CFB) with annular furnace and six circulating loops to study the effect of structural arrangements on gas-solid flow in the annular furnace and flow non-uniformity among six loops.The results show that suspended surfaces,symmetric mode of the six cyclones and the inner ring structure of annular furnace have little effect on the axial distribution of solid volume fraction in the furnace.The existence of suspended surface,centrosymmetric arrangement of the six cyclones vs axisymmetric arrangement,and the single pillar structure vs the two pillars structure are benefit for the improvement of non-uniform distribution of circulating rates among six loops.But the improvement is limited,and the distribution regularity of circulating rates among six loops is not changed.It can be inferred from the comparison of past study with this work that the key factors influencing the distribution uniformity of circulating rates among six loops should be the layout of the cyclones at ends and the chamfer structure of the outer walls.关键词
