efficiency

Most readers will receive this issue while they are experiencing Northern Hemisphere winter, with its colder temperatures and higher energy bills, so it’s fitting that several articles address efficiency. You’ll find discussions of combined heat and power (CHP) as well as a refresher on the various ways to enhance thermal unit efficiency and thereby improve […]

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).
