METHOD FOR OPERATING CHLORINE BYPASS SYSTEM AND CHLORINE BYPASS SYSTEM
To provide a method for operating a chlorine bypass system and a chlorine bypass system which can suppress pressure loss while maintaining cooling performance without oversizing a probe.SOLUTION: Provided is a method for operating a chlorine bypass system comprising: a probe for mixing an extraction gas obtained by extracting a part of a combustion gas from a kiln with a primary cold air and executing primary cooling; and a secondary cooler for mixing the mixed gas obtained by mixing the extraction gas and the primary cold air in the probe with secondary cold air and executing secondary cooling. The secondary cooler comprises: a cylindrical mixing chamber connected to the probe; and plural discharge ports respectively discharging the secondary cold air toward a perpendicular direction to the flowing direction of the mixed gas in the mixing chamber and to the central direction of the flow of the mixed gas. A ratio of the total momentum of the secondary cold air discharged from the plural discharge ports to the momentum of the mixed gas in an inlet of the mixing chamber satisfies 0.6 to 2.0, and a value obtained by dividing the air speed in the mixing chamber by the inside diameter of the mixing chamber satisfies 10 to 50 (s-1).SELECTED DRAWING: Figure 2
【課題】プローブの過度な大型化をすることなく、冷却性能を維持しつつ、圧力損失を抑えることができる塩素バイパスシステムの運転方法及び塩素バイパスシステムを提供する。【解決手段】キルンからの燃焼ガスの一部を抽気した抽気ガスに、一次冷風を混合して一次冷却するプローブと、プローブで抽気ガスと一次冷風が混合された混合ガスに、二次冷風を混合して二次冷却する二次冷却器と、を備える塩素バイパスシステムの運転方法であって、二次冷却器は、プローブに接続される筒状の混合室と、混合室内の混合ガスの流れ方向に対して直角方向、かつ混合ガスの流れの中心方向に向かって二次冷風を各々吐出する複数の吐出口とを有し、混合室の入口における混合ガスの運動量に対する、複数の吐出口から吐出される二次冷風の総運動量の比が０．６～２．０を満たし、かつ混合室内の風速を混合室の内径で除した値が１０～５０（ｓ－１）を満たす。【選択図】図２
