Minimum Recommended Protection, Interlocking and Control for Fossil Fuel Unit-Connected Steam Station IV. Air and Fuel Systems

The various systems that make up a fossil fuel unit-connected steam station require minimum interlocking, control and accurate sensing of the process variables for starting them in a coordinated order to insure proper start-up. This paper becomes part of a set of companion papers that describe start-up and safe shut-down of the Boiler-Turbine-Generator unit.
