Valve Leak Detection and Monitoring
Aging plants, deteriorating valve performance, and increased demand for electric power require careful monitoring for any potential loss of efficiency and generation. This type of valve leakage is one of the largest and often most overlooked issues in nuclear, fossil, and CCGT power plants. Curtiss-Wright's Cycle Isolation Monitoring technology quickly detects valve leakage issues and estimates the leakage rate as well as the generation and heat rate impacts for each leaking valve. Available as an independent software solution or as a part of the FAMOS product suite, Curtiss-Wright's Cycle Isolation Monitoring module presents real-time data in a web-based platform that uses advanced temperature and stream calculations to quickly detect cycle isolation issues, then estimates leakage and heat rate impacts for each leaking valve. The module can also compare the cost of continued operation versus repair - allowing users to make informed decisions about the health and efficiency of their systems.
The Cycle Isolation Monitoring module calculates the net effects of valve leakages in terms of heat rate and/or generation losses, allowing power plants immediate insight to improve efficient plant operation.
Undetected valve leakage causes damage that increases the leak and the repair costs. By offering critical insight into valve performance, the Cycle Isolation Monitoring module allows power plants to balance MW losses against planned outages and determine the most effective maintenance scheduling based on their individual needs.
The Cycle Isolation Monitoring module uses downstream temperature data to create valve leak alerts. Additional tools allow users to set up automatic notifications, alarms, and reports that are delivered to users and captured in the historian.
Combining real-time data and web browser displays, the Cycle Isolation Monitoring module quickly detects valve leak issues and automatically estimates the leakage rate along with power generation and heat rate impacts for each leaking valve.
