Analysis and Automatic Control System Designs for Main Propulsion Machinery

摘要

The report presents a summary of the background and experience of the Naval Boiler and Turbine Laboratory in the field of automatic control of marine steam power plants. It is intended to provide information to specification writers, ship designers, machinery suppliers, and control system contractors that will be of value to them in their task of establishing the detail requirements for automation system design in accordance with the best state-of-the-art design practices. Dis cussion of recommended practices, with examples of current problems, is presented for control systems for boiler water level, steam pressure, air flow, fuel flow, and auxiliary machinery and systems. General application of system design philosophies are discussed.
