Two-stage steam ejector (horizontal)
The function of the steam ejector is to extract the non-condensable gas and the air leaked into the steam side space of the condenser from the inside of the condenser under negative pressure, so as to maintain the vacuum and thermal performance of the steam side of the condenser.

The role of steam ejector
The function of the steam ejector is to extract the non-condensable gas and the air leaked into the steam side space of the condenser from the inside of the condenser under negative pressure, so as to maintain the vacuum and thermal performance of the steam side of the condenser. The two-stage steam ejector works with the operation of the condenser when the turbine works normally. The two-stage steam ejector consists of two single-stage steam ejector (primary and secondary) and a surface cooler in series.
The working principle of the jet steam extractor
The working principle of the steam ejector is that the mixture of non-condensable gas and steam from the steam side space of the condenser is sucked into its mixing chamber by the first-stage steam ejector, and mixed with the high-speed steam emitted from the nozzle in the first-stage mixing chamber. Enter the first-stage diffuser and discharge into the first-stage cooler after compression. After the mixture of steam and gas is cooled in the primary cooler, the non-condensable gas and part of the end-condensed steam are sucked by the secondary injection steam extractor, mixed with the high-speed steam emitted from the nozzle in the secondary mixing chamber, and then discharged into the secondary diffuser after compression. After the mixture of steam and gas is cooled in the secondary cooler, the steam is cooled into condensed water, and the air is discharged into the atmosphere.
