Due to the multiple nozzles, it is used to reduce the steam consumption by 9-17 % as compared to the single-stage ejector and thus it is more efficient. Also, its length is considerably short. It helps to provide continuous flow through suction media. Ejector eliminates the chances of fire or explosion as there are no moving parts in it.
