•Case Study: 770MAX Provides Reliable Multiparameter Monitoring For Cycle Chemistry
To assure reliable operation of aging power plants, on-line instrumentation must be upgraded periodically. The THORNTON 770MAX Multiparameter Analyzer/Transmitter, used with up to four analytical sensors with Smart Sensor technology, makes upgrades especially easy. Its compact size, its greater functionality and accuracy make the changeover a true upgrade.
AEP Appalachian Power Company Clinch River Station in Virginia, USA The AEP Appalachian Power Company Clinch River Station in Virginia has three coal-fired 235 MW units built in the early 1960s. They are highly efficient for plants of that vintage. Various modifications to those units have been implemented over the years to maintain that high performance. A recent change replaced the deteriorating sampling equipment and analytical instrumentation monitoring Unit #3.
770MAX combines with
Smart Sensor technology
Despite the use of other instrumentation
on the other two units, for this upgrade
the plant chemist chose the THORNTON
770MAX because of the Smart Sensor
technology, convenient menu-driven
operation and compact four-channel
design. The need to replace equipment
for conductivity, dissolved oxygen and
pH was matched very well by 770MAX
capabilities which allowed the measu–
rements to be configured in the most
straight-forward combinations.
