  • Deferred Maintenance Increases Pump Failures

    If your facility has recently seen an upsurge in bearing failures on boiler feedwater (BFW) pumps, you are not the only plant experiencing these unnecessary and costly failures. The failure causes are often elusive, which is why plants have so many unresolved repeat failures.

  • Pre-Combustion Technologies: A Key Environmental Compliance Tool

    Arizona Public Service’s (APS) plan to close three older coal-fueled units at the Four Corners Power Plant in New Mexico and buy out Southern California Edison’s 48% share of the two remaining units is a creative means of surviving the U.S. Environmental Protection Agency’s (EPA) committed action against coal-fueled generation.

  • The Great Solar Storm of 2012?

    The 2009 blockbuster movie 2012 about a global cataclysm combined Hollywood special effects with supposed predictions by Nostradamus; a Mayan calendar that ends on December 21, 2012; and a very rare planetary alignment that supposedly occurs on the same day. Hollywood producers seldom let technical accuracy get in the way of a good story, but suppose, this one time, the story has an element of truth.

  • Readers Write

    In the September and October 2010 issues, POWER Contributing Editor David Daniels explored the causes and damage mechanisms of condenser tube leaks (“Taming Condenser Tube Leaks,” Part I and Part II). Dennis J. Schumerth, Valtimet’s director of business development, took issue with several of Daniels’ statements regarding the proper use of titanium condenser tubes. We have given Schumerth the opportunity to express his concerns and for Daniels to reply.

  • Increasing Generation Ramp Rate at Morgantown Generating Station’s Coal-Fired Units

    At Morgantown Generating Station, plant personnel used innovative methods to combine model predictive control with distributed control system–based process control algorithms to improve waterwall temperature control and main steam temperature control and to enhance unit ramp rate capability. The previous heat rate and NOx optimization performance gains were retained. Focusing beyond basic loops of feedwater, air, and O2, the project considered issues such as PID controller override configuration and limitations. The techniques used to overcome these challenges improved unit ramp rate capability beyond any previous unit performance.
