97-09: On-Line Performance Monitoring of the 1300 MW Natural Draft CoolingAmerican Electric Power's past and current approach to determining and monitoring performance of natural draft cooling towers on coal fired generating units from 260 1300MW size will be discussed in the paper. The paper will focus on the Gavin Plant on line performance monitoring system approach with prior testing activities on AEP System cooling towers included from a historical perspective.

This paper describes a new Aseptrol ClO2 delivery system that is capable of at least two months of unattended operation in small-to-medium-size cooling systems up to 30

utilizing the most common sediment side stream filtration technologies

The most nearly correct approximation of airflow through a tower can be obtained by incrementally moving through the tower from air inlet to outlet while calculating mass flows

ATP and petri-films have long been the standard for microbial detection

forcing the 800 MW coal-fired generating unit out of service

should give the same results

the overhead condenser and a dollar cost which could easily pay for

This paper presents several cases where condenser performance monitoring tools quickly and accurately documented condenser performance changes and highlighted the value of making those changes

we must look into the basic mechanism of corrosion of metals and see how all these factors can in­fluence the basic reaction

while eliminating the fouling previously experienced due to inorganic loading

many design features must be considered to produce optimum performance

The occurance of fan stall appears to be a common factor in an increasing number of cooling tower thermal performance problems
