The Marine Gas Turbine Regenerator Material and Fabrication Considerations Free

Gas turbine heat exchangers of the stationary and rotary types are used to increase power-plant thermal efficiency. Economic justification for the use of regenerative equipment depends on the criteria of initial cost and component life. Materials selection and fabricating techniques must be in accord with cost and life objectives. In this regard, the U. S. Navy Ship Systems Command has sponsored a program to investigate the particular problems associated with marine gas turbine heat exchangers. This paper presents the results of the investigation to date.
