A method is presented for predicting the performance of modern steam turbine-generator units designed for high efficiency levels. This method is based on recent developmental and analytical results. The necessary curves, tables, and instructions are provided for the application of the method to a large variety of units of various kilowatt ratings, types, and steam conditions. Relative heat-rate curves are presented and mathematical expressions are provided for computer applications.

The Naval Boiler and Turbine Laboratory has recently completed an evaluation and development program of a supercharged steam generator system. The installation for this program was the only one of its type in the United States. The agenda developed and the test facility and instrumentation system designed were specifically adapted to the requirements of a supercharged system. Modifications required during the development and the test results obtained are briefly discussed. As a result of this program, supercharged steam generators are being installed in the Navy’s DE1040 Class ships.

Part 1 of the paper presents an analytical formulation of the design and performance of an a-c thermoelectric generator utilizing the periodic flow of heat across a surface, with the thermoelectric conductors in the form of deposited films or ribbons woven through a dielectric sheet. Part 2 formulates the efficiency of this type of a-c thermoelectric generator in a manner which will lead to payoff optimizations in accord with various application criteria.

A method of analysis is presented which gives all of the natural frequencies and mode shapes of a laced group of rotating steam turbine exhaust blades. Both flexural and torsional motions are considered, which are coupled through the lacing wires. The frequency determinant of the vibrating packet is derived by the Fundamental Solution technique. The analysis is facilitated by separating the symmetric and skewsymmetric modes of vibration. The natural frequencies are found by the conventional trial-and-error procedure. Digital computation is required.
