Valve Temperature Monitoring at a Steam Power Plant
Challenge
Engineers operating a steam power plant need to monitor the temperature of all the valves to identify possible energy losses and to schedule repairs.
Solution
To allow for quicker, more frequent, and more efficient scanning of target valve population tailpipe temperatures, a series of FlexPower Thermocouple Nodes and FlexPower Battery Supply Modules are installed.
Temperature measurements of the valves and pipes are measured and wirelessly transmitted to a DXM100 Wireless Controller mounted in a central location. The DXM100 gathers the data and transfers the data to a SCADA system that monitors and graphically displays the temperature data.
Temperature trend data is used to identify steam plant energy losses and repairable valve leakage–related heat rate degradation factors.
