01-05: Cooling Tower #4, Fan FailureThe Chocolate Bayou Plant is a world class chemical plant located in Alvin, Texas about 40 miles south of Houston. The plant chemical processes are cooled by 3 mechanical draft cooling towers with a combined recirculation rate of 267,000 gpm. In March, Cooling Tower 4 experienced a catastrophic failure of the #8 fan. The root caused investigation indicated serious corrosion problems with fan equipment, reliability problems with vibration detection

A large outbreak of Legionnaires’ disease in the Bronx in 2015 prompted NYC to enact law and NYS to propose emergency regulations on the registration and maintenance of cooling towers

The relative effective of the oxidant (work value) must be taken into account to achieve automated control

An existing fan performance prediction code was used to identify desirable airfoil characteristics for large tapered/twisted blades

You have a better chance winning at roulette than protecting your cooling towers with mechanical vibration switches
