Project Title:
Feasibility study of using abradable seals for sealing of 25
MWgas turbine and compressor components
Department: Metallurgy
Employer: NRI
Project Staff: A.A. Fallah, E.Rezabeigi
Project Manager: M.R. Shirpay
Project Code: PMTBC04
Project Summary:
One of the priorities of ministry of energy is to improve the efficiency and power of gas
turbines. Various tasks were employed by the manufacturers to increase the efficiency
of the gas turbine. One of the methods to improve turbines efficiency and power is the
sealing and minimizing leakage in compressors and turbines. Maximum reduction of air
spacing leads to decrease leakage and cause improvement of the gas turbines efficiency
and power.
In this project, technical specification of the sealing and the methods of application for
different parts on 25 MW gas turbine have been provided; and finally application of
such sealing on different parts of compressor & turbine has been assessed from the
technical and economical point of view.
Project Results:
133
• Preparing spesifications of abradable seals for gas turbine.
