Point Level Capacitance Switch for Fly Ash Hopper Measurement
If you’re the person tasked with controlling the level of fly ash in collection hoppers, you know how difficult the application can be. What at first looks like a simple measurement quickly proves to be much more demanding in actual execution. The first problem is the environment inside the collection hoppers, which is extremely challenging […]

Gaining Control with Electraulic Actuators
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 was experiencing an efficiency decrease of 5% to 7%, which plant engineers determined was caused by poor performance of the actuators on their condensate level control valves (CLCVs).
