WATER INJECTION SYSTEM OF AXIAL MULTISTAGE COMPRESSOR Russian patent published in 2014 - IPC F04D19/02 

FIELD: mechanical engineering.

SUBSTANCE: water injection system of an axial multistage compressor, having tubes and outlet channels, further comprises a fairing, in this case the fairing is located in the area of the front edge of each guide blade of the axial multistage compressor with a possibility to form a slot-type channel. Each tube is positioned in a longitudinal cavity formed in the area of the front edge of the indicated blade, and has holes made by the blade height to provide a uniform vapour flow by the section of an air flow, and outlet channels are made at the front edge of each indicated blade, in this case the slot-type channel, and the outlet channels are designed in each guide blade of the axial multistage compressor with a possibility to provide a nonseparated water flow and air flow. In addition, each tube has a heat-protective material.

EFFECT: development of the water injection system of the axial multistage compressor without causing the additional hydraulic and wave losses, that doesn't require high degree of water purification.
