New edition of POWER magazine is now available. In February 2013 issue, you can get latest information in the power generation industry such as layup practices for fossil plants, plant automation advancements, coordinated feedwater heater energy control and more. Here are feature articles for this month.
Coordinated Feedwater Heater Energy Control
The increased use of intermittent renewable energy sources and the shift to gas-fired combustion turbines places new burdens on the dispatch of many coal-fired units. Steam units must now operate at very low minimum load while maintaining the ability to ramp up and down quickly. High-pressure feedwater heater energy control can improve the system response of such coal-fired units.
Plant Automation Advancements: The Australian Experience
Many recent utility greenfield and rehabilitation power projects have incorporated plant automation, with the goal of reducing the number of operators needed. The essential design principle is to specify control systems and field devices that will achieve the desired operational regime. Here’s how it’s done “Down Under.”
Too Dumb to Meter, Part 8
As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the 14th and 15th chapters, “A Man, a Plan, a Canal” and “The End of the Exploding Game,” the final two chapters of “Eddie Teller’s Exploding Ambitions” section.
A Moderating Tone from the EPA on 316(b)?
Final water intake structure rules from the EPA expected this June suggest the agency may be listening to industry and even moderating its tone. Stretch goals as part of the Section 316(b) rule are likely, but overall the rule may prove more reasonable than many expected.
Thermocouple Response Time Study for Steam Temperature Control, Part II
Mismatched or poorly maintained temperature sensors and thermowells can cause an often-unrecognized error in steam temperature measurement. The problem is often recognized only when sluggish steam temperature response times are noticed. Recent tests suggest some simple ways to resolve the problem.
Getting Distributed Energy Resources Right
Rick Tempchin, executive director, Retail Energy Services for the Edison Electric Institute, talks about the impact of distributed energy resources on utilities and their customers.
Sediment Pond Effluent pH Control
Many power plants have sediment retention ponds that require control of pH for the effluent. The following guidelines for fossil plant sediment pond pH control will help you design a robust system while staying within budget.
