Thermal power plants for peak-load and emergency service

摘要

The paper discusses first the operating conditions and distinguishes between the different classes of service' to be furnished by stand-by plants. Subsequent sections deal with the choice of fuel, and the fields of application of oil-engine and steam plants. It is shown that only steam plants are suitable for large outputs, to which the greater part of the paper is accordingly devoted, explaining the particular requirements affectingthe auxiliary supply, the arrangement of the stations, and the turbine and boiler design, and describing the means and types of equipment which have been evolved to meet those requirements. Finally, three short sections deal respectively with instantaneous stand-by steam plants, automatic stand-by steam plants, and various recent installations of special interest.
