TP14-20: Premature Failure of Open and Closed Recirculating Cooling Water and Fire Water Systems Piping and Equipment: Are You Responsible? Treatment Control

TP14-20: Premature Failure of Open and Closed Recirculating Cooling Water and Fire Water Systems Piping and Equipment: Are You Responsible? Treatment ControlIn recent years there have been a relatively large number of unexpected, premature failures of system water piping associated with HVAC, Process Cooling, and Fire Water systems in modern buildings designed for commercial, residential, health care, governmental, and manufacturing occupancy. Facilities designed to provide long term service life are failing due to severe corrosion resulting in complete penetration of circulating water piping as a result

the fill media

Particularly

Molybdate-based chemicals have been used as corrosion inhibitors in cooling tower systems for several years

one of the two seven cell mechanical draft cooling towers serving American Electric Power's (AEP) 780 MW Conesville Unit 4 suddenly collapsed into the cold water basin

A third phase

The paper also discusses practical applications of the model to cooling tower plumes

Due to its unique property of polymers

a great deal of care is taken in establishing the program and the necessary controls

The test report is described

their reasons

To prevent calcium scaling

This paper takes a look at four issues associated with the transition between the cooling tower and the pump intake
