【摘要】 本文从理论上对水泥窑多级旋风预热器,或预热加预分解系统的各级旋风筒分离效率对总体分离效率与热效率的关系进行了分析论证,并导出了有关公式,从而可以不必通过复杂的计算机模拟方法而简单地,直接从各级旋风筒效率计算系统总体分离效率及飞灰灰量,并估算由于高温(下部)旋风筒效率变化对出预热器废气温度之影响,最后,根据理论分析结果,对具有多级旋风筒之预热器窑,或预分解窑之设计原则提出建议。并论证了各级旋风筒之效率高低匹配应为: E(1)>E(5)>E(2)>E(3)>……E(S)更多还原

【Abstract】 The relation of the individual stage’s collection efficiency to the total collection and heat efficiency of the multistage cyclone preheater (for preheating plus precalcining system)have been analysed theoretically, for- mulas have been derived, for the calculations of total efficiency and for the estimation of the exhaust gas tem- perature change、due to the change of the lowest stage’s efficiency, finally, principals for the design of multistage cyclone preheater were proposed.更多还原
