Fossil Plant Startup Advisor: Volume 1, Analytic startup evaluation technique: Final report
The concept of an analytical cost function to optimize drum boiler startup procedures is developed and an example is presented. Terms in the cost function include cyclic life expenditure of boiler and turbine components, fuel costs, load errors, maintenance costs, and auxiliary power costs. In addition, other factors such as water chemistry and acid deposition are discussed. The example shows a comparison of a variable pressure startup versus a constant pressure startup using the Commonwealth Edison Collins unit as the test case. Some sensitivity tests are also presented that show the cost impact of the two procedures when starting from different initial temperatures. A proposed application of the cost function concept as a startup advisor is described. The startup advisor can be used off-line or on-line. When used on-line, it can be used in either a monitoring mode or a predictive mode. A demonstration system is described based on a dynamic model of the Collins unit modified to include a turbine bypass system as well as a superheater bypass system. The system runs on an IBM PC or compatible and is operated manually using the keyboard. The purpose of the demonstration system was to show the significance of different startup configurations and operating procedures at several utility locations. 28 figs., 4 tabs.
