Proper Valve Trim Extends Life of Boiler Feedwater Valves

Boiler feedwater valves operate under severe service conditions and are subject to premature failure from seat leakage, cavitation, particulates, and frequent cycling. However, once the type and root cause of

Controlling Boiler Level When Operating Conditions Change

The right level instrumentation is key to keeping boilers on an even keel. Guided-wave radar offers a critical combination of capabilities. If asked to make a short list of factors able to improve heat rate

Working with Peers Is Critical to Power System Reliability [PODCAST]

When conversations around the power industry turn to computer hacking, more often than not experts say it’s not a question of if, but rather, how systems have been compromised. William Doering, adjunct professor in the online Master’s in Business Administration program at Maryville University and a director with Guidehouse—a management consulting services provider—said he has participated […]

Severe Modulation in Feedwater-Control Valves Reveals Need for Periodic Calibration

Some combined cycle plants have two feedwater-control valves: a small startup valve with the extra cavitation protection needed during startup and low-load operations, and a larger main valve with the high flow capacity needed during full-load ops. This design is intended to yield a longer service life of these valves. However, as the plant ages, […]

DERMS Technology Part of Australia’s Push for Renewables

A new distributed energy resources management system (DERMS) is being deployed in Western Australia, designed to manage distributed energy resources (DERs) across nearly 1 million square miles, with a focus on

Making the Connection: Digitization Ramps Up Optimization

Power generators continue to expand their use of digital technologies. Data analytics, artificial intelligence, and machine learning are all part of a rapid transformation in how utilities are improving the

A Grim Gap: Cybersecurity of Level 1 Field Devices

Industrial control system cybersecurity is today largely focused on securing networks, and efforts largely ignore process control equipment that is crucial for plant safety and reliability, leaving it woefully
