HVAC Control in the New Millenniumbutton to initiate the following automatic actions:• purge the furnace,• perform comprehensive header leak tests on all the fuels,• open the trip valves,• bring the first igniter and burner on-line, and• bring the furnace up with additional burners as needed.A saturated steam curve ignition run-up is used and burners are bypassedthat fail to go into service. If a boiler is cold, it is pre-warmed,firing it at a level according to the cold-boiler-run-up steam curve. Theseactions speed the process of responding to load demands. The burnermanagement system has algorithms that assist in the required configurations.ReferencesFuller, James L., Robotics: Introduction, Programming, and Projects, Merrill,an Imprint of Macmillan Publishing Company: New York, 1991.Harvey, Charles and Peter Wise, “New BMS and DCS Provide Reliableand Responsive Power Plant Automation,” Instrumentation & ControlSystems, Vol. 72 No. 11, November 1999, pp. 59-61.Redman, Jim, “Upgrades Enhance Capability,” Industrial Computing, Vol.18 No. 5, April 1999, pp. 22-25.Rinehart, R.R., “Model-based Control,” Instrument Engineers’ Handbook,3rd Edition, Chilton Book Company: Radnor, PA, 1995.Riorda, Michael, “The Incredible Shrinking Transistor,” Technology Review,Vol. 100 No. 8, November/December 1997, pp. 48-50.Zink, John C., Ph.D., P.E., “Power Plants Merge Information and ControlSystems,” Instrumentation & Control Systems, Vol. 72 No. 11, November1999, pp. 55-57.©2001 by The Fairmont Press, Inc.
