Cycling of High-Pressure Steam Power-Generating Units with Drum Boilers (EPRI CS, 2340)

Analyses and results of cyclic tests on 500-MW high-pressure power-generating unit with a drum-type boiler are presented. Descriptions of cycling problems and methods to reduce them are summarized, development of a new analytic model of transient boiler operation is reviewed, and details are provided of the cyclic testing program and correlation of test results with the transient boiler model. A suggested procedure for optimizing cycling operation of the test unit is outlined.
