Boiler steam drum level control is critical in electrical power generation. Too high a level can mean water aspirating into the steam lines and causing damage to the turbine generator blades downstream. Too low a level can cause the boiler to dry and overheat. In a Power magazine article, Controlling Boiler Level When Operating Conditions […]
Some processes, such as oil & gas production, not only have to measure liquid levels but sometimes must measure sediment levels that can come along in the production stream and settle in vessels and tanks. This quick, 2:38 “How To” YouTube video, How Does the Rosemount Sand Switch Functionality Work?, shows how to change the […]
Common in the Life Sciences and Food & Beverage industries are clean-in-place (CIP) operations to effectively clean the interior surfaces of production process piping, vessels and other inline assets before the next batch is run. This short, 2:10 YouTube video, Effective Conductivity Measurement in Clean-in-Place Applications, highlights the importance of extremely tight measurement and control […]
When you hear discussions about “the cloud” you often also hear about “the edge” where higher resolution processing can be performed. For manufacturers and producers, this edge may extend to the instrumentation itself measuring and controlling the process. In a Control Engineering IIoT for Engineers supplement article, Extend edge data gathering with multivariable instruments, Emerson’s […]
A NACE International paper, HRSG Tube Failures: Prediction, Diagnosis and Corrective Actions highlights the challenge of these failures: Many HRSGs were originally designed for base load operation. Recent economic factors have led to drastically increased cycling of many units. This has exacerbated the rate of failures. These leaks can lead to forced outages that create […]
