description: The subject of the graduate qualification work is the study and improvement of the exhaust pipe of the drive steam turbine type P-16-3,4/0,8 NZL. The study gives the relevance of the purpose, forms the objective of the study. The paper gives a review of steam turbines of various manufacturers, and considers variants of designs of exhaust nozzles of steam turbines of different capacities, directions of improvement of performance efficiency. Numerical modeling of the unified exhaust nozzle of the drive steam turbine type P-16-3,4/0,8 NZL, as well as 4 variants of its modernization is carried out. The analysis of the compared exhaust nozzles was carried out and the modernized exhaust nozzle with the lowest total loss coefficient was obtained. It is expedient to further study the modernized exhaust nozzle in the system âlast stage-exhaust nozzleâ, because even better performance can be expected. The obtained data and conclusions are of great interest for the manufacturer.
