CALCULATION AND ANALYSIS ON TEMPERATURE DROP OF FLUE GAS BETWEEN TSS AND FSS IN RFCC UNIT

介绍了催化裂化装置三旋至四旋烟道内烟气温降的计算方法,建立了对该烟道设计有指导意义的理论公式,并对影响温降的因素进行了分析。此举既优化了烟道气工艺设计又节能降耗。

A method for calculating temperature drop of flue gas in flue between TSS (Third Stage Separation) and FSS (Fourth Stage Separa- tion) in RFCC Unit is introduced,a theoretical equation which is in- structive and helpful for flue design is established,and analysis on fac- tors affecting temperature drop is made.
