COVER STORY: ASSET MANAGEMENT
18 Layup Practices for Fossil Plants
Electric Power Research Institute (EPRI) research confirms that improper layup practices
are a major contributor to boiler tube failures and to steam turbine pitting and
cracking-a major cause of reduced plant reliability and availability. To help you
avoid such problems at your plant, adopt the best practices that EPRI has identified.
SPECIAL REPORTS
INSTRUMENTATION & CONTROL
26 Plant Automation Advancements: The Australian Experience
One operator controlling two units-without even being in the control room? Some
may find the idea alarming, but it's a mode made possible, and safe, by careful design
of control automation systems, including alarms.
32 Coordinated Feedwater Heater Energy Control
By delivering increased power generation and reducing NOx emissions, feedwater
heater energy control can be a vital component of a multivariable boiler, load generation,
emissions, and steam temperature control system. Comparative operating
scenarios are presented.
36 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.
