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

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 ...

They work in harsh environments, and they get little or no recognition. But their impact on power plant efficiency can be significant. Valves and actuators are critical in almost every aspect of power ...

Plasma synthetic jet actuators (PSJAs) represent a cutting‐edge approach to active flow control by utilising pulsed plasma discharges to generate high‐speed jets. These devices have garnered ...

Plant engineers at Eskom’s Majuba Power Station in South Africa have been continuously looking for ways to improve efficiency and reliability. The six-unit, 4,000-MW, supercritical coal-fired plant ...

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, ...

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