The invention discloses a steam ejector with high ejection performance. The steam ejector comprises a main nozzle, a mixing chamber assembly and a diffusion chamber which are sequentially connected along the center line. The mixing chamber assembly at least comprises two mixing chambers which are connected in sequence; the inlet of the gradually-shrinking section of the first mixing chamber is connected with the outlet of the gradually-expanding section of the main nozzle, the throat of the first mixing chamber is connected with the inlet of the gradually-expanding section of the next mixing chamber, and so on, the inlet of the gradually-shrinking section of the last mixing chamber is connected with the outlet of the throat of the previous mixing chamber; the throat outlet of the last mixing chamber is connected with the inlet of the diffusion chamber; and each injection channel is provided with a check valve. The large pressure difference between the inlet of the diffusion chamber and the inlet of the ejecti
