Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...

Learning the basics can ease loop tuning frustration and ensure stability. During plant operations, it seems that tuning control loops is an ongoing task, which can be a continual frustration to ...

Integrated slug-flow optimization can mitigate flow problems in a wide range of both offshore and onshore operating conditions. Slug flow is one of the most common flow states in horizontal and ...

Flow is controlled by either throttling or diverting it. Flow is controlled by either throttling or diverting it. Throttling involves reducing orifice size until all of the flow cannot pass through ...

Off-highway construction machinery can exponentially benefit from a simple system upgrade to improve efficiency and overall ...

Compressible fluid flow through control valves will inevitably cause some form of flow-induced vibration in the fluid system. Identifying the type and cause of the vibration requires detective work.

Optimizing any cooling plant for minimal energy consumption is a demanding science. In many cases, minimizing chiller plant energy consumption requires modifications to the plant design, including ...

Choked flow in control valves is a subject of serious concern for industrial users. The term is usually associated with destructive process conditions that can damage valve internals or expose ...

Valves and actuators are critical in almost every aspect of power plant operations. They are used in a wide range of applications, including pollution control, feed water, cooling water, chemical ...

Many power plants use older control valve technologies that do not address the severe nature of today’s power plant operations. The older design valves require constant maintenance and their ...

Piezo elements are electromechanical transducers that convert mechanical forces (pressure, tensile stress or acceleration) into voltages. The inverse piezoelectric effect, precisely the opposite, ...
